For Listen and Practice (listen and repeat) modes to work properly, ReadAloud will mark up your model audio so that it pauses and highlights the text currently being spoken.
When using TTS (machine voice) as model audio
Model audio mark up is done automatically when you are using a TTS (text to speech) voice.
ReadAloud will guess at the correct locations to put break points. But you can tweak the break points and set them manually from the model audio tab.
To tweak the break point, tap the space or word before the space to toggle the break point on or off.
When using a recorded speaker as model audio
Model audio mark up is also done automatically when you are using an audio-recording/uploaded-audio as model audio. However there will be a delay while that audio is transcribed. After recording or uploading wait 5 mins and refresh the page to see the automatically created breaks.
Manual Break Timing
Use "manual break timing" if:
a) the sync between breaks and the audio location is not precise enough.
b) the model audio breaks are not created automatically.
This can happen if the TTS voice does not support time stamps. This is currently true for some languages, including Hebrew, Tamil and Telegu.
This way requires the teacher to play the audio and while playing tap the location in the passage that matches the audio playback point, to toggle the breaks. To begin this,
- Check "manual break timing"
- Begin playback by pressing the audio player play button
- Tap the break point when the audio reaches it
- Tap the next break point when the audio reaches it ..
