FAQ

Q. No sound is playing. What should I do? Check that your volume is set appropriately. No sound is played in silent mode. Playback may be delayed due to network conditions; if nothing plays after a few seconds, press REPEAT to retry.

Q. The voice quality is poor. What should I do? Check the text-to-speech engine settings and update to the latest version. Adjusting the pitch may also help. Setting procedure:

1. Open your phone's "Settings".
2. Select "Language & Keyboard" or "Language & Input".
3. Select "Voice" or "Text-to-Speech".
4. Open "Voice Settings" or "Text-to-Speech Output".
5. Adjust the "Pitch" slider (slightly right of center often sounds more natural).
6. Preview with the "Listen" button and adjust to your preference.

• Setting methods may vary by Android version and device.
