If the audio in Avaz is not working, check the following:
- Check if the iPad volume is working, through iPad Audio settings. Check if the audio is present in other apps / music from the iPad. If it is not, then press the Volume buttons on the side of the iPad, to increase the volume. For more information, click here - How to increase the volume in the iPad.
- If you are using Avaz AAC, the subscription version of Avaz, the Avaz trial / subscription may have expired. On expiry of trial / subscription, the voices will not work, until you purchase a subscription.
- Check Avaz Audio settings
Sometimes the Avaz audio may have been set to a setting where every selection does not speak the word out on selection. But this can be changed based on the child's needs.
Tap Menu > Settings (Screenshot below) 
Scroll down to Audio Settings and tap the What to Speak button. (screenshot below)
Select Speak Everything if you want all selections to be spoken. (screenshot below))
