setRate method

Future<bool?> setRate(
  1. num rate
)

Set rate (tempo) for next utterance

1.0 is the normal speech rate, lower values slow down the speech (0.5 is half the normal speech rate), greater values accelerate it (2.0 is twice the normal speech rate).

Implementation

Future<bool?> setRate(num rate) =>
    TextToSpeechPlatform.instance.setRate(rate);
