Brief conf report: English UK North Academic - University of Liverpool, October 7th.

Yesterday I got on the train from York to Liverpool (in what ended up being an endless 3 1/2 train-train-bus journey...yes, transport may also fail in Britain!) to attend and present at the English UK North Academic conference (programme here).

It was a really friendly, welcoming environment of teachers of English working in the North of the UK, and there must have been over 100 attendees.  I would like to very briefly report on three of the talks, and then comment on my own presentation as well.

Michaela Seserman from the University of Liverpool discussed the tools she uses in her EAP courses to do pronunciation work. Michaela discussed some important questions we need to ask prior to deciding to use certain apps, and also weighed some pros and cons of each. Seserman proposed a form of integration of the in-built voice recognition systems that smartphones currently hold, the tools that Quizlet offers, and the messaging possibilities of the WeChat platform. Even though it was perhaps not very clear how pronunciation improvement actually came to happen, the idea of teacher and students exchanging audio recordings for practice and dictation via mobile messaging is a very appealing one. As Michaela pointed out, these are tasks that learners can also spontaneously decide to do outside class.

Russell Stannard, the TeacherTrainingVids guy, showed how screen capture software (he recommends SnagIt but there are free alternatives available) can help you give better feedback on written work. So a teacher may videocapture a student's written assignment and give feedback (as we might do face-to-face), by highlighting areas of the essay, for instance, and making oral comments on it, or showing the assignment instructions on screen to point out what may not have been addressed. It reminds me of the type of recorded feedback I used to give my students, and I agree with Russell that this whole idea of personalising feedback and having a sort of "conversation" with the student and the material really does make a difference. It's a way of "being there" when you cannot "be there", while also showing students we care for them individually and that we can address each of their specific strengths and challenges -which in writing we may fail to do clearly, or which may be misinterpreted-.

I particularly enjoyed the workshop on corpus linguistics by Dr. Vander Viana from the University of Stirling. Vander showed us some easily accessible corpora (sorry, readers, but I cannot ensure that this will be freely accessible to you in your context/country) and search engines that we can use to help our students test the frequency, acceptability and likelihood of their lexical choices when writing, or speaking. We discussed collocations, colligation, and semantic prosody (which apparently in corpus ling is different from how we understand it in SFL!), and we reflected on the claim that we actually process speech in an "idiomatic" way (not referring to idioms, but to chunks....it was such a great intro point to my own talk later, to be honest!). Most of the cited material came from Sinclair (1991); McCarthy et al (2005); and Tognini-Bonelli (2001), and you can read Viana's work if you visit his webpage.

I was invited to make a presentation thanks to the generosity of Mark Hancock, who put my name forward (I've thanked him publicly many times, but I believe we should always be grateful to the ones who do nice things for us)...and to make it even better, he got me a PronPack t-shirt! And also thanks to Nigel Paramor.
Even though I know my stuff, it is always a bit intimidating to stand in a room full of native speakers of English who teach English and theorise about their own language. I know it is a silly fear, but I know many other non-native teachers of English will sympathise. Anyway.

My talk ("Intonation building blocks for more comprehensive speaking skills training") was based on the type of speaking tasks that I designed for my Lab 3 and Lab 4 lessons at ISP Joaquín V González and Profesorado del Consudec during the last few years. Some background: most of the work that is done during the final two Applied Phonetics modules ("Lab") in teacher training in Buenos Aires (at least) is related to the application of phonological theory to the production of different speech genres (and for this, I am grateful to Prof. Silvina Iannicelli, because I got my first lecturing post filling in for her at ENSLV SBS in 2006, and she had a course planned along a sequence of texts ranging from rehearsed to more spontaneous text type production, and that sort of sparked my interest in the prosodic configuration of speech genres). As I became a bit more experienced, one of the things that usually made me uncomfortable about the type of work we did in these courses was that most of the tasks were based on reading, and there was always an assumption that intonation patterns were easily/automatically transferrable to spoken situations of language use. (It's a bit like doing a million fill-in-the-gap past tense exercises, and then expecting students to automatically and spontaneously use the simple past in their written or spoken stories.)
Plus, at times we also forget that reading aloud is an ability in itself, and that reading aloud as a result of previous imitation of a recorded model of the same text is also another type of ability that activates other skills and requirements. These are highly useful and valuable steps in the process, but they do not amount to, nor ensure, that the students will appropriate intonation patterns. In my tutoring experience, I have had students producing English fall-rises in reading and Spanish rise-falls on the exact same phrase, on a similar context, when speaking.

So at some point in my tutoring/lecturing history, I decided to change that a little, and to use reading aloud as one of the steps of the process, but then also create opportunities for use in slightly more spontaneous speech tasks in a way that ensures that students need to use certain intonation patterns that have been found to have a certain regularity in specific speech genres, or in connection to certain lexico-grammatical structures.

So, back to EUKN: My talk was about speech genres, and how several speech genres have higher degrees of "writtenness" in them (Eggins, 1994), and how these have perhaps more easily predictable and stable patterns of intonation and chunking; whereas more interactive genres challenge the intonational descriptions as we know them (such in the case of "list intonation", or the intonation of questions).

I put forward the metaphor of building blocks as a means of proposing that for some speech genres, it is useful to see information units (and some lexicogrammatical collocations) as part of the same block that students can monitor as a whole as they plan their next block (rather than worrying about putting together a string of words, one after the next, when they talk).

I have followed a process that goes from the breaking of the dichotomy between spoken vs written texts, into a continuum of levels of writtenness-spokenness (as SFL scholars have done for a couple of decades), and the use of a building block metaphor consisting of LEGO type blocks that occur in more written-like spoken genres (where the blocks have a set role, position, and the final goal is clear), and TETRIS blocks that we may encounter in more interactive texts (where trajectories are built as we go along, and there are lower levels of pre-planning.

I will only be able to share a few of my slides, as I am writing an article/resource on the whole notion and application of intonation blocks (and I'm also seeking psycholinguistic and further classroom evidence), and I owe the English UK North attendees the preview of the full set of slides (because I have authorised EUKN to do so).

Some comments on challenging, through corpus-study, the notions of "question intonation", and "list intonation". How intonation in real life as manifested in different speech genres does not easily exhibit the intonation patterns described in ELT textbooks.



Reflection upon the fact that we generally don't do speaking training in an integrated manner, as we may do with written genres.
Possible (though never definitive, nor exhaustive, nor always fixed, because language use.... ;) ) organisation of different speech genres along a cline.
The building block metaphor I propose to inform lexico-grammatical, sequential and intonational choices.


An example of a production task (which probably we have done in our lessons a million times!) that we can exploit to teach step-ups in pitch, and contrastive accent.
Examples of lexico-grammatical blocks in initial position that do anticipatory work. These have been found to be quite consistent in LEGO types of texts (the ordering and tone choice works differently in interactive texts)
Example of an outline for student production of short conversational stories that focus on grammatical choices and the preparatory (loop) or advancing (increment) contextualisation by rising or falling tones (respectively)

Example of ways in which we can contextualise reported speech through level tones and contrastive stress in TETRIS-like situations of language use (though also common, with direct speech, in speeches, or lectures, LEGO text types)

Examples of ways in which we can create opportunities for use of level tones in conversational lists (vs counting, or sequences of steps where lists may be found to have rising tones)

During the presentation, I systematised briefly some of these (basically, it was like teaching my whole Phonetics 2 syllables in 50 minutes!) and presented a number of activities to illustrate how we can generate opportunities for use of these building blocks, and then, of course, it is up to every teacher to find ways of helping students monitor their spoken texts, block by block. 

I am sure that the idea of working on speech chunks is not new, or revolutionary, but I wish to emphasise how intonation can be an active, essential, part of each of these blocks of processing and production, and how the notion of a block can contribute to students' awareness that linguistic structures work together, making different contributions in the contextualisation of meaning and structural organisation of speech.

(And the refs!)



All in all, this was a really enjoyable event, and very special for me, as I haven't been teaching for a year (starting this week again, yay!) and I spent this whole year trying to find an excuse to write down the principles and ideas that informed my integrative intonation teaching methods when I was lecturing in Buenos Aires. Hope they make sense to you!

(And now...back to my research. Enough productive procrastination!)

P.S.: this post somehow opened up a chest of memories for me, and I forgot to acknowledge another lecturer, Prof. Claudia Gabriele, who in her own way showed me that there are ways of "creating opportunities" for practice of intonation. I was her Lab assistant for a few years, and I was particularly inspired by her use of role plays and other speaking tasks for a more natural application of intonation patterns. Sorry about this unintentional omission in the original post.

Talk like Hawking: Teaching with a synthetic voice

Hiya! I have been pretty busy and also a bit disappointed in life lately (soo dramatic!), but blogging has always been good medicine, so I'm back! 


***
I have always found voice matters interesting, and I do pay a lot of attention to people's voices in general. They have the power of generating feelings, immediate gut feelings, in me. 

For many years, I was concerned about my own voice, as it would invariably become hoarse and then turn to a whisper at least twice or three times a year. I was teaching over 55 periods a week and as we all know, our teaching activity is a 100% dependent on our voice (there's a limit to emergency video sessions one can plan when your voice's "on the blink"!). So I was basically "killing my voice softly".

Things changed for the better when I started training in vocal technique, and I will always be grateful to Carlos and Liliana at Instituto de la Voz for having saved me from potential hiatus and nodule problems. And I have now got the huge responsibility of passing on these techniques and voice care tips to my teacher trainees, which I try to do on a regular basis. 

Now. This whole babble is related to today's blog post, since in spite of all my care, my voice was gone yesterday due to an irritating bout of flu or something (and the winter temperatures hitting our country like we haven't seen for a number of years!). With several classes a day to teach, all pronunciation-related, how do you keep going?

Well, the obvious answer is: "You don't. You go home, you see a doctor, you get some rest for a few days till you recover". And that would be the right answer. But it's not always possible. So here's what I did yesterday.

***

Teaching Phonetics the Hawking-style

We are all familiar with Stephen Hawking. We all know what a miracle it is that he can share all his wisdom and knowledge with us through a computer. Therefore, I used him as an inspiration to try to teach my class without having to strain my voice.



So here's what I have done:

1) I typed part of my lecture at home, on my tablet (It runs an Android Kit Kat operating system).

2) I downloaded the following app: Talk, and selected English (GB) as the output voice. (I was in a bit of a hurry, so this is the first app that worked for me, but I will be comparing it with others below)

3) I tried the app out, and noticed that to make it less "robotic", I had to "teach" the system to read the way I wanted it to read. That is, I had to input extra punctuation marks, such as "" and ; to allow the machine to chunk units apart or produce some basic intonation patterns which would allow my audience to follow more clearly.  I also had to simplify my clauses and exploit thematic marking on the text to make sure my synthetic voice would signpost topics and paratones more clearly to my students.

4) I gave my tablet Internet access via my phone, using it as a router, since this app needs a working connection, and of course, I connected my tablet to my portable speakers.

The immediate result? Giggles, of course! It was fun. I got called "Marina Hawking". But it was, of course, not the same as being able to respond to students' queries in real time. I eventually had to replace the use of my tablet for the whiteboard when I needed to reply to students' queries on the spot. 

I wanted to brag and I finished my lesson by typing in "That's all, folks!", but the awful rendering by the system (giving "folks" a separate IP and using a fall) spoiled all the fun! (Try it!)


However, I was teaching a theoretical class, so the app did the trick. I had a Lab lesson right afterwards, and it was really difficult to succeed in this way. I was not in a position to deliver feedback on the spot, since obviously, my app would not read IPA symbols, and the need for synchronous comments while the student is reading out, or speaking, does not match my typing speed. In this particular case, gestures and the whiteboard did the job. Sort of. My teacher assistant allowed the class to happen, to be honest!

(Had I had a data projector, I would have projected the text my students were reading, and I would have highlighted their slips and mistakes on the spot, to allow them to at least see what I was trying to comment on! I could have also projected some vids and audio files from some of the pronunciation apps I reviewed in the past.)

So all in all, a text-to-speech act may save the day, but you defo need to take care of yourself and try to get your voice back asap!

***
Free Text-to-Speech Apps

After yesterday's experience and while resting in bed, I decided to review a few other apps that may do the job nicely.

(I will review them together, as they are very similar and use the same voice database. The same text was read by both apps identically, and with the same voice. They only differ in their interface.)
  • These apps allow you to paste your text, or type it straightaway, and play it out. (Easy Text to Speech does not require any text-pasting, it just reads from your clipboard)
  • You are able to choose from a long list of languages and accents.
  • You can export or save your audio file.
  • You need an active data or Internet connection.
  • Tip! You need to "overpunctuate" your text to avoid a robotic output.



This application uses its own voice database. You choose an accent, and a speaker, and you download the voice database for that voice in particular. I have chosen "Amy, UK English". So far, it sounds like the most natural reading option, because the voice is somehow soothing. 

It has not, of course, reached the state of artificial intelligence, in that it does not chunk my text the way I would like it to, and it does not always employ the intonation I expect, but it does recognise a few chunks and it appears to be able to recognise patterns of declination and paratones. 

This application also allows you to set your preferred pitch and speech rate for the chosen voice.

From what I have been able to make out, it does not need an active Internet connection. The voice data files I have downloaded were 150 MB, so I guess it should all be "there".

Even though it is not a text-to-speech app but rather a translator, I cannot help feeling surprised about the changes that Google has introduced to their voices and to the whole reading aloud experience. It still sounds pretty "robotic", but there are some chunks of language that the system automatically recognises and reads out with some fixed intonation patterns. This creates an overall "weird" effect, since you hear upsteps, downsteps and sudden tone changes that make the whole text sound incohesive at times, but less so, if compared to what it was like last year!

BTW! I have found a tip on how to get Google to read out a phrase out for you. Type in this address in your browser:

http://translate.google.com/translate_tts?tl=en&q=type your phrase here

And replace the bit that says "type your phrase here" with your own phrase, and voilá!



Much as I love Google, Microsoft has done a better job in terms of making their performance of read-out texts more natural. The Bing Translator option presents, in my humble opinion, a better chunking, and more natural selection of intonation patterns. 

See for yourself! Compare the output versions of a short paragraph of my lesson by both Google Translate and Bing Translator. Look out for some interesting word stress choices as well!

Final remarks and a few extras...

  • A full selection of Android text-to-speech apps is available here.

Hope this blog post has been of use! It has certainly inspired me to start considering writing a paper on synthetic-speech talk and intonation!

Phonetics-To-Go: Mobile Apps for Pronunciation Practice


Today I made a very humble presentation at one of the Colleges I work at, and the one I graduated at as well, for the annual "Jornadas", organised by a special commission in the English Department called EDAPI.
Bad hair day, as usual :p

I have decided to call the presentation "Phonetics-To-Go", as I have mostly done a review of some free or "low-cost" mobile apps I have found that allow you to take pronunciation with you, everywhere!

A few disclaimers:

  1. I have only reviewed free apps, free trials and some 1-dollar apps. I know there are brilliant paid apps out there, but they exceed the scope of my presentation...( and my pocket at the moment!.)
  2. The inclusion of these apps in my PowerPoint slides does not entail any endorsement. During the presentation I listed some of the pros and cons of each app and made a point of whether they include ads or require further payment, for instance.
  3. I have focused on a few apps and a few skills. I know there are more advanced apps out there that allow you to work with spectograms and waveforms, to mention but a few, but I have addressed the profile of my audience and I have mostly focused on ELT.
  4. I don't get any benefits out of reviewing these apps. Feel free to try them, and test them, install them or uninstall them, but do so at your discretion.
  5. Not all apps will work on all devices, in spite of the operating system. For example, the apps for Blackberry only run in BB10 devices.
  6. Before downloading an app, always read its description, check the company/individual behind the design, and particularly focus on the "permissions" you need to grant for the app to work on your device.
  7. What to do with these apps and how to apply them in your lessons is a choice you will need to make for your own groups, levels and culture. I will, in the future, devote a post to possible uses for these apps.


Having made all the preliminary remarks I thought fit (faithful to my usual quest for "down-to-earthness"), here's the PowerPoint for you:

Hope you find these apps (and my warnings) useful!
Best,

Tools & Apps #1: Typing IPA symbols



Today: How to insert IPA fonts in a document, website, mobile device....and more!

(Disclaimer 1: I know there are lots of posts on this in pronunciation- and tech-related blogs, and there are many tools I am not reviewing here, which you can consult in my Scoop.It collection at the end of this post. I am just presenting the ones I myself have found useful, with the usual warnings and "user discretion" advice!)
(Disclaimer 2: I have tested these tools on a Windows 7 and a Windows 8 computer, and on mobile devices running Android 4.1 and Blackberry 10.2 versions. I cannot help those Mac/iOS users out there, I fear, though some of these may work on these systems as well.)


The easy way out



There are a number of "phonemic typewriters" on the web you may want to try out. In general, all you have to do is to click on the keys and transcribe your desired words/passage. You then select your transcribed text and copy and paste it on Word, on the Web, on Twitter, on Facebook, you name it!




  • I have found David Brett's typewriter really useful when in a rush, for a basic broad transcription, though given some recent changes to GB you may not find all the symbols you need. 

    David Brett's
    Pete McKichan's Phonemic Script Typewriter below works similarly.
    McKichan's


If you need to go for narrow transcription with different diacritics and symbols for other languages than English, you may try Typeit .






Weston Ruter uses the IPA chart to function as a typewriter. Great resource if you need to be reminded of the place and manner of articulation of the symbols you are typing, among other features:










Even easier? Think again!


Yes, dear students, we've known about these for YEARS! And I have trained my eye to recognise transcriptions using these tools. Because what matters in the end is the rule behind the use of a certain sound for a certain spelling, or the choice of a particular weak and strong form, these websites may not be "the coolest" thing to use (especially if you have to sit face-to-face exams, where your knowledge should come straight from your head!). So, yes, these resources may be time-saving, but not grade-savers in the end. So think twice before using them to complete your homework transcriptions. And if you do use them, check the transcriptions against your spelling and weak-strong form rules, trying to account for every bit transcribed, or attempting to spot "errors". 
(Now, having made my usual "witch lecturer" warning, off to reviewing these tools)


Some websites offer a text-to-pronunciation transcription. Yes, they do! I myself have used them to prepare some keys to transcriptions or dictations for my lessons, but found I had to use up quite a lot of that time I thought I'd saved correcting errors or making more suitable choices of pronunciation. 

One of the most popular among my students (Busted!) is PhoTransEdit. You can see from the capture what I mean about "correcting mistakes", but I have to admit it is one of the most accurate tools of this kind I've found so far in spite of some "horrors":
Lingorado offers a similar functionality, but uses /ɛ/ for British English /e/, and it also presents a few issues with weak and strong forms and happY, for instance:

***
Many of these have iPhone, Android and Windows 8 mobile versions, which makes IPA-typing on your mobile or tablet easier. Other mobile apps I have tried on Android and Blackberry 10 include:

Multiling Keyboard: I found this integrated keyboard hellish to use at first, but once I got used to it, I could type IPA really easily. You just need to get acquainted with the location of the symbols on the keyboard and learn some swift movements to make your choice, but the keyboard includes diacritics as well, and I believe all the trouble is worth it. I have produced transcription keys on the spot for my learners, typing almost at the same speed rate they were handwriting their symbols on the page!


Phoneme Converter: if you are familiar with the shortcuts for the IPA symbols to type on a PC (see below), then this tool is going to allow you to type really fast using ASCII-IPA (say, using the @ for /ə/, for example) in order to paste your text later anywhere on your mobile device. This is a capture of its use on a Blackberry 10 device, though it is in fact an Android app:

A bit more challenging, but worth it! 


Indeed, having the IPA fonts in your computer does make things easier for us, and yes, it does pose a bit of a challenge. But once you are over the initial struggle of download and installation, all you need to do is remember the codes to type those symbols that just "don't look like regular letters", so to speak.

UCL (includes also a phonetic keyboard):  http://www.phon.ucl.ac.uk/resource/phonetics/
  • How to install the fonts
Some of the websites above present the fonts as "packages" which "self-install" the fonts with the only task of downloading and opening the file. Some others, however, require manual installation.
If that is the case, on a Windows computer, these are the usual steps:
1. Download your fonts, and if zipped, unzip them.
2. On the File Explorer, copy them (or select them and click "ctrl + C") as you would do with any file.
3. Open the Control Panel. Double click on "Fonts"
4. Paste your files (or click "ctrl + V")
That should do the trick!
  • How to type the symbols
If you use a word processor, for instance, you just need to identify the name of your font and select it on the list of fonts,  in much the same way you change from Arial to Times New Roman, for example. 
The symbols that look like letters, so to speak, are typed directly, and if you need to consult the way of typing in the other "foreign-looking" symbols, you can check the article below:
(Mind you, there is a "logic" behind the system, with the velar nasal /ŋ/as a capital N (shift + n), the STRUT vowel /ʌ/ as a capital V, the NURSE vowel /ɜ/ by pressing "3", and so on! You'll be up to it in no time!)

Intonation

Regarding intonation, things may be a bit "rough", particularly if you use tonetic marks, unlike the conventions used for ToBI that use letters and some (*%!-+) symbols.
Those keyboard tools that offer diacritics do have tone marks you can use, and the fonts listed above also present a few, particularly the one on intonation at the UCL website.
At times, however, it appears to be more useful to use arrow marks with superscript and subscript formatting options . Some people  use slanted lines \ /, others, following the conventions of Discourse Intonation, place words on different lines to show key/termination variation.
These may be just some ways of coding your transcription for intonation, which will depend on your chosen theoretical framework.

Truth is, marking different levels of key and termination may prove a bit of a struggle. There are a few fonts going round, but as I cannot accurately trace the source, I cannot post them just yet. Should I get permission and a reliable source, I will make them available here, I promise! 


IPA tools: My bag of tricks



As usual, here's my full collection of resources to type IPA symbols.
http://www.scoop.it/t/pronunciation-bites/?tag=ipa+fonts
 The links to some of the resources reviewed here will be found in this collection, as well as many other tools I have not reviewed because of their price, effectiveness or accuracy. You can check them out and tell us about your own experience in the comments box below.

A final word

Being able to transcribe on your PC or your mobile gives you the chance of not only showing the pronunciation of a particular word or phrase on the spot, but also, and more importantly, it gives you the freedom to design your own flashcards, acrostics and other teaching materials on any web platform or piece of software. If you use the typewriters, for instance, you can also embed the symbols on Facebook, Twitter, and your blogs and platforms, allowing us "phonfreaks" to share knowledge or code "secret" messages for other "phon-nerds" worldwide!
