Flutter微软文字转语音

直接使用 Flutter 进行http请求不用插件，以下是请求微软语音合成后生成音频文件

  // 请求微软文字转语音
 static Future<String> postMicrosoftMusciFile(String text) async {
   String authorization = AzureAudioManager().appKey;
   String region = AzureAudioManager().appRegion;
   String ssmlContent = '''
 <speak version='1.0' xmlns='http://www.w3.org/2001/10/synthesis' xml:lang='zh-CN'>
     <voice name='zh-CN-XiaoxiaoNeural'>
         $text
     </voice>
 </speak>
''';
   String url =
       "https://$region.tts.speech.microsoft.com/cognitiveservices/v1";

   Map<String, String> headers = {
     "Authorization": authorization, // 请确保正确设置了Bearer令牌
     "Content-Type": "application/ssml+xml",
     "X-Microsoft-OutputFormat":
         "audio-16khz-32kbitrate-mono-mp3", // 输出模型
   };

   Dio dio = Dio(); // 创建Dio实例
   BaseOptions options = BaseOptions(
       // baseUrl: baseUrl,
       receiveTimeout: const Duration(seconds: 10),
       sendTimeout: const Duration(seconds: 15),
       connectTimeout: const Duration(seconds: 15),
       responseType: ResponseType.json,
       headers: headers);
   dio.options = options;
   options.responseType = ResponseType.bytes;
   final response = await dio.post(
     url,
     data: ssmlContent,
   );
   // 请求成功，返回音频数据 (字节数组)
   if (response.statusCode == 200) {
     Directory appDocDir = await getApplicationDocumentsDirectory();
     String appDocPath = appDocDir.path;
     // 创建文件
     File file = File('$appDocPath/music.mp3');
     // 将下载的内容写入文件
     await file.writeAsBytes(response.data);
     LoggerUtils.logDebugPrint(file.path);
     return file.path;
   } else {
     SmartDialog.showToast("voice error，code=: ${response.statusCode}");
     return '';
   }
 }

播放可以直接使用flutter_sound这个库就行了

  // 播放语音文字
 Future<void> playAiTTS(
     {required bool allowBlue,
     required String text,
     double banlace = 0,
     required VoidCallback finish,
     int playType = 0}) async {
   var path = "";
   try {
     path = await Api.aiTTs(text: text, playType: playType);
   } catch (e) {
     Logger().w(e);
     finish();
     throw Exception(e);
   }
   await playMP3(
       allowBlue: allowBlue, path: path, banlace: banlace, finish: finish);
 }
