Media sources l.jpg

Media Sources

  • Voice of America

  • Using text to speech


Text to speech l.jpg

Text to Speech

  • Good for non native speakers

  • Good for lone native speakers

    • TOEIC questions use male and female voices


Voices l.jpg

Voices

  • There are various voices

  • The free ones such as in “Wavepad” are bad

  • AT&T produce the best.

  • Cepstral has an audio file broadcasting licence for only about $230, which is quite reasonable. Alas however their voices are not quite at the same quality. They specialise in lighter faster voices. “Diane” may just about do.https://www.cepstral.com/demos/

Bit rate and sample rate l.jpg

Bit Rate and Sample Rate


Flash compatible sample rates l.jpg

Flash Compatible Sample Rates

  • Sample rates are 44Khz, 22Khz or 11Khz. (Thread)

  • The bit rate should not matter

  • This should be simple


Audacity changes things martin using 44khz l.jpg

Getting the microphone to work!


Script l.jpg

Script

  • Dialogue (Questions and Answers)

  • Question about dialogue

  • Four answers

  • Improvisation from initial dialogue question?


Toeic tips l.jpg

TOEIC Tips

  • The correct answer and the question-about-dialogue use different language to the dialogue: triple paraphrase.

  • Distractors use dialogue language OR homonyms OR paraphrases of dialogue language.

  • All answers different: reduces “strategy.”

  • All about the same length: correct NOT longer

  • All answers require dialogue: Non-grammatical / non-sequitur / counter common sense answers not allowed.


How many audio files l.jpg

How many audio files?

  • Six

  • 1) Dialogue

  • 2) Question

  • 3,4,5,6) Four answers including one correct answer

  • Can reduce to three but then the correct answer can not be randomized and the students can cheat.


Where to store the files l.jpg

Where to store the files

  • External Server – anyone can listen to them

  • Course files – only when logged in

  • Course files – big backups

  • Course files – exchange backups

  • External Server – exchange gift files

Importing questions to moodle l.jpg

Importing Questions to Moodle

  • GUI or TEXT file

  • Text file is faster

  • GUI may be easier to use


Slide52 l.jpg

GUI

  • Allows attachment of images via quiz interface but not yet audio files.

  • Can attach audio files using the html editor

  • Can be slow if using server.

  • I recommend installing “Moodle for Windows” or “Moodle for Mac” into your desktop


Gift format l.jpg

GIFT format

  • This is the way to go.

  • The file format is the same for every question!

  • Just change the question title.


Gift gotchas l.jpg

GIFT Gotchas

  • Escape character \ before = in links

  • Escape character \ before ~ in urls

  • Save as UTF-8 or EUC to suit your Moodle’s encoding

  • Notepad only saves in SJIS so need “Sakura Editor” (Google it)

  • Correct answer random position

  • Do not use file names that give away the correct answer.


Universal audio gift question l.jpg

Universal Audio GIFT question

  • Please listen to the dialogue <a href\="URLXquestion1_dialogue.mp3"><img src\="URLXchime.gif"></a> <br/>Now listen to the question <a href\="question1_question.mp3"><img src\="URLXchime.gif"></a><br/>Now listen to the responses, and select the one that best answers the question.{~<a href\="URLXquestion1_response1_a.mp3""><img src\="URLXchime.gif"></a>#No. ~<a href\="URLXquestion1_response1_b.mp3""><img src\="URLXchime.gif"></a>#No.=<a href\="URLXquestion1_response1_c.mp3""><img src\="URLXchime.gif"></a>#Yes!~<a href\="URLXquestion1_response1_d.mp3""><img src\="URLXchime.gif"></a> #No. }

  • Using gif for audio – makes it a little more difficult to get the URL. Html entity “&nbsp” also okay

  • URLX replace later for server or course file URL

  • Escape character \ before “= ”

  • Feedback should be better than this in reality.

  • Not universal: change position of right answer
