It's working fine on android and iOS simulator, however when using an iOS Device(Iphone), the audio does not play at all.

  • It seems impossible to circumvent the silent mode, but you can detect it and notify the user about text-to-speech not working when the silent switch is on. See [this answer](https://stackoverflow.com/a/67326679/1014048). – Ivan Mir Apr 30 '21 at 00:30

For the TextToSpeech to work properly on the Device the Ringer (button on the left side hand) needs to be turned On.

The Speech synthesizer in iOS is controlled by the ringer volume, not the media volume.

Hope this helps.-
