Developing online listening exercises for natural English

In our context, we can render the unclear audio to text by listening to it, parsing it mentally, saying it back into the SR engine, and then creating text manipulation exercises from it that force students to attend to certain details in the text / speech. We have created Hot Potatoes exercises where the audio is embedded in the exercise and the students can play the audio, complete the exercise, and get a score. This explains how and why we do it.

Developing online listening exercises for natural English

  1. 1. Developing online listening exercises for natural English Presented at the TESOL Arabia Conference in Dubai, March 13, 2015 by Vance Stevens
  2. 2. Access this presentation later • Written version of this presentation http://tinyurl.com/tacon2015vance That’s - tacon2015vance • Slides on http://slideshare.net/vances
  3. 3. Pedagogical challenges • “Teaching” listening materials in large classes • Getting machine-readable text from audio media • Creating exercises accessible on student devices (PC’s, iPads) in 1-to-1 contexts • Tracking student progress efficiently
  4. 4. Easy: Getting text from print • Scan it to OCR • PDF to Word conversion • One Note – copy text from image • Speech recognition More difficult: Text from speech
  5. 5. Speech Recognition SR • Discrete – Phone routing systems – Traci Talk • Continuous – Natural language processing – Dragon Systems
  6. 6. Dragon on iPad • Strengths – Fairly accurate – Easy to use – Works offline • Weaknesses – Can’t see text while recording – Not easy to correct text – Getting text from iPad
  7. 7. Dictanote on PC • Strengths – See text as you speak – Full set of text processing tools – Autocorrect • Weaknesses – Must be online
  8. 8. Affordances for combined skills • Start with Audio – Speak it into an SR engine to get text – Present student with audio enhanced with • Reading material • Machine-readable text support • Online audio practice exercises • Start with text – Speak it into an SR engine to get soft text – Record it in Audacity simultaneously – Present student with a reading enhanced with • Audio support • Machine-readable text support
  9. 9. Pedagogical implications • Students can read at pace of recorded audio • Provides audio support for silent reading • Paste text into Google Docs, share with students – FIND vocabulary words (contextual practice) – Create text manipulation exercises – Quickly find / display examples / teaching points
  10. 10. Getting text from unclear speech • Develop Hot Potatoes exercises that – Embed audio or video – Allow students to pace and repeat audio – Provide copious materials to teach / assess listening comprehension – Allow teachers to track completion of assigned tasks • Start with unclear audio – Speak it into an SR engine – Present student with audio enhanced with • Reading material • Machine-readable text support • Online audio practice exercises Air Traffic Control recordings tend to be unclear in places
  11. 11. Delivery of Multimedia HP • Multimedia Hot Potatoes comprises 2 files – A Hot Potatoes html file – A multimedia file • Both files must be proximal for the lesson to run. How can we package them? – Zip files – RAR files – Scorm
  12. 12. Together they look like this Try it: http://vancestevens.com/kbzac/hotpots/videolistening/sukhoi.htm
  13. 13. Code added in configuration menu For Audio <audio controls> <source src="sukhoi.mp3" type="audio/mpeg"> Your browser does not support the audio tag. </audio></br> For video <video width="320" height="240" controls> <source src="Sukhoi.mp4" type="video/mp4"> Your browser does not support the video tag. </video></br>
  14. 14. You can also embed online media From the embed code supplied here: https://soundcloud.com/pilotedge/full-ifr-clearance <iframe width="100%" height="150" scrolling="no" frameborder="no" src="https://w.soundcloud.com/player/?url=https%3A//api.soundcloud.com /tracks/24468540&color=ff6600&show_artwork=false"></iframe>
