I need your questions! What's wrong? What's not clear? Let me know.
This shouldn't happen... if it is, please please contact me. You could also try turning off the phone and back on.
The application uses the system text-to-speech engine to read out the numbers. To manage settings on your device go to Settings > Language and input > Speech > Text to speech output. (The exact steps will vary from phone to phone.)
If you can't find these settings, make sure you have installed TTS (text to speech) on your phone. You can install it from the Google Play Store.
Currently, the languages supported are determined by your device and browser. The easiest thing to do is to try a different browser. If that doesn't help, you may need to install the language for your operating system.
Be sure that you are wearing headphones and have the volume turned up. If still don't hear anything, try using a different browser. If you can't get it to work at all, please let me know!
Thanks! Currently, the system using computer generated voices for numbers. But this may change in the future. If you are interested, be sure to join the email list and be on the lookout for the request!
If you have any other questions, please contact me.
