  1. MakingMultimedia Quizzes Using Moodle Timothy Takemoto Department of Tourism Studies Faculty of Economics Yamaguchi University

  2. Media Sources • Voice of America • Creative Commons Audio • Recording your own audio • Recording your own video • Using text to speech

  3. Text to Speech • Good for non native speakers • Good for lone native speakers • TOEIC questions use male and female voices

  4. 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/

  10. Record your own You will need: • Recording Software • Hardware • Moodle Pre-Setup • Audacity Set-up • Script Writing • Importing Questions

  11. Audacity

  12. Mp3mymp3 for students

  14. Hardware

  15. Cheap microphone Into computer sound card.

  16. Mp3 Player/Recorder

  17. Good Quality Sound Recording

  25. Steps in Creating A Quiz

  26. Turn on the Moodle Media Filter.

  27. Setting up Audacity 1 • Download Lame Encoder (Google “Lame encoder”) • http://www-users.york.ac.uk/~raa110/audacity/lame.html

  28. Setting up Audacity 2

  29. Bit Rate and Sample Rate

  30. Flash Compatible Sample Rates • Sample rates are 44Khz, 22Khz or 11Khz. (Thread) • The bit rate should not matter • This should be simple

  31. Audacity Changes things! (Martin)Using 44Khz • 44Khz changed to 11Khz 16bs okay • 44Khz changed to 16Khz 24bs super chipmunk • 44Khz changed to 22Khz 32bs okay • 44Khz changed to 32Khz 40bs chipmunk • 44Khz changed to 32Khz 48bs chipmunk • 44Khz 56bs okay • 44Khz 64bs okay • 44Khz 80bs okay • 44Khz 128bs okay

  32. Getting the microphone to work!

  33. Script • Dialogue (Questions and Answers) • Question about dialogue • Four answers • Improvisation from initial dialogue question?

  34. 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.

  35. 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.

  36. 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

  37. Post Processing with Audacity

  38. Noise removal 1 Select Noise

  44. Normalisation 1 • Select all the audio: Control A

  45. Normalisation 2 • Select Normalize effect from the Effect Menu

  46. Normalisation 3 • Defaults OK for low volume audio

  47. Normalisation 4 • Result – Spreads out the wave pattern to use the dynamic range. Effectively reduces noise.

  48. Compression 1 • Compression from Effect menu

  49. Compression 2 • Defaults okay, or increase ratio

  50. Compression 3 • Click Okay
