Thank you for contributing to the development and improvement of Cloud Text-To-Speech!
There are essentially two ways to use Cloud Text-To-Speech:
TtsProviders.google
, TtsProviders.microsoft
, TtsProviders.amazon
to use the single provider at a time.TtsProviders.combine
to combine all providers and get all voices at once.To init configuration use:
//Do init once and run it before any other method
TtsUniversal.init(
provider: TtsProviders.amazon,
googleParams: InitParamsGoogle(apiKey: 'API-KEY'),
microsoftParams: InitParamsMicrosoft(
subscriptionKey: 'SUBSCRIPTION-KEY', region: 'eastus'),
amazonParams: InitParamsAmazon(
keyId: 'KEY-ID', accessKey: 'ACCESS-KEY', region: 'us-east-1'),
withLogs: true
);
To change provider use:
TtsUniversal.setProvider(TtsProviders.microsoft);
To get the list of all voices use:
//Get voices
final voicesResponse = await TtsUniversal.getVoices();
final voices = voicesResponse.voices;
//Print all available voices
print(voices);
//Pick an English Voice
final voice = voices
.where((element) => element.locale.code.startsWith("en-"))
.toList(growable: false)
.first;
To convert TTS and get audio use:
//Generate Audio for a text
const text = "Amazon, Microsoft and Google Text-to-Speech API are awesome";
final ttsParams = TtsParamsUniversal(
voice: voice,
audioFormat: AudioOutputFormatUniversal.mp3_64k,
text: text,
rate: 'slow', //optional
pitch: 'default' //optional
);
final ttsResponse = await TtsUniversal.convertTts(ttsParams);
//Get the audio bytes.
final audioBytes = ttsResponse.audio.buffer.asByteData();
To init configuration use:
//Do init once and run it before any other method
TtsUniversal.init(
provider: TtsProviders.combine,
googleParams: InitParamsGoogle(apiKey: 'API-KEY'),
