synthesize method

Future<File> synthesize(TextToSpeechRequest request, { int optimizeStreamingLatency = 0, })

Synthesize text to speech Takes a TextToSpeechRequest object and a value from 0 to 1 on how much to optimize for streaming latency Returns a HistoryItem object

Implementation

Future<File> synthesize(TextToSpeechRequest request,
    {int optimizeStreamingLatency = 0}) async {
  try {
    Response<dynamic> response;
    if (optimizeStreamingLatency != 0) {
      response = await _dio.post(

        data: request,
        queryParameters: {
          'optimize_streaming_latency': optimizeStreamingLatency
        },
        options: Options(

    final responseFile = await File(fileName).writeAsBytes(response.data);
    return responseFile;
