synthesize() - RunAnywhere Documentation

// Get the audio back
final audio = await RunAnywhere.tts.synthesize('Hello from RunAnywhere');

// Play it
final handle = RunAnywhere.tts.speak('Hello from RunAnywhere');

Signatures

Future<Audio> synthesize(String text, {TtsOptions? options})
Stream<AudioChunk> synthesizeStream(String text, {TtsOptions? options})
SpeechHandle speak(String text, {TtsOptions? options})
Future<void> stop()
Future<List<Voice>> voices()

speak is synchronous and returns the handle immediately. stop is async.

Options

final audio = await RunAnywhere.tts.synthesize(
  'Hello',
  options: TtsOptions(voice: 'en_US-amy-medium', speed: 1.1),
);

await File('${directory.path}/out.wav').writeAsBytes(audio.samples);
