Customizing Voice with DashVoicesConfig​

DashVoicesConfig allows you to finely tune the text-to-speech (TTS) systems used in your application. This feature provides the flexibility to fine tune the voices for your application's requirements.

Here's an example of how to use DashVoicesConfig to customize the voice settings:

Dash.init(
    context = this,
    accessToken = getString(R.string.mapbox_access_token),
) {
    voices {
        selectedVoice = PrebuiltDashVoices.voice1
        preferLocalTts = true
        localTtsEngine = "com.samsung.SMT"
    }
}

Parameters​

  • SelectedVoice: Specifies the remote voice for speech synthesis. Ignored when preferLocalTts is true.
  • PreferLocalTts: Chooses between local and remote voices. If true, only the local voice is used. If false, the SDK primarily uses the remote voice, switching to local in poor network conditions.
  • LocalTtsEngine: Defines the local TTS engine. Defaults to the system's default if the specified engine isn't found. Use Android's TextToSpeech to find available engines.

Runtime Updates​

DashVoicesConfig supports updates at runtime, allowing the voice settings to be adjusted while the application is running.

Dash.applyUpdate {
  voices {
    preferLocalTts = settings.isLocalTtsEnabled
  }
}
