## 使用说明 |
||||
|
|
||||
|
### TTS 语音合成 |
||||
|
|
||||
|
#### 基础用法 |
||||
|
```dart |
||||
|
import 'package:volcano_speech/volcano_speech.dart'; |
||||
|
|
||||
|
// 初始化 |
||||
|
await VolcanoSpeech.initialize(appId: 'YOUR_APP_ID', apiKey: 'YOUR_API_KEY'); |
||||
|
|
||||
|
// 设置音量、语速等参数 |
||||
|
await VolcanoSpeech.setSpeechParams( |
||||
|
rate: 0, // 语速: -500到500，0为正常速度 |
||||
|
volume: 100, // 音量: 0到100，默认100 |
||||
|
pitch: 0, // 音高: -500到500，0为正常音高 |
||||
|
silenceDuration: 500, // 静音段时长: 毫秒 |
||||
|
); |
||||
|
|
||||
|
// 设置音色 |
||||
|
await VolcanoSpeech.setVoice( |
||||
|
voiceName: 'zh_female_qingxin', |
||||
|
voiceType: 'qingxin' |
||||
|
); |
||||
|
|
||||
|
// 开始合成并播放 |
||||
|
await VolcanoSpeech.speakText(text: '这是一段测试文本'); |
||||
|
|
||||
|
// 暂停播放 |
||||
|
await VolcanoSpeech.pausePlayback(); |
||||
|
|
||||
|
// 继续播放 |
||||
|
await VolcanoSpeech.resumePlayback(); |
||||
|
|
||||
|
// 停止播放 |
||||
|
await VolcanoSpeech.stopSpeaking(); |
||||
|
|
||||
|
// 销毁引擎 |
||||
|
await VolcanoSpeech.dispose(); |
||||
|
``` |
||||
|
|
||||
|
#### 进阶用法 |
||||
|
```dart |
||||
|
// 设置工作模式 |
||||
|
await VolcanoSpeech.setWorkMode(mode: TtsWorkMode.alternate); // 先在线，断网时切换离线 |
||||
|
|
||||
|
// 设置离线发音人 |
||||
|
await VolcanoSpeech.setOfflineVoice( |
||||
|
voiceName: 'xifei', |
||||
|
voiceType: 'qingxin' |
||||
|
); |
||||
|
|
||||
|
// 下载离线资源 |
||||
|
await VolcanoSpeech.downloadOfflineResource( |
||||
|
voiceTypes: ['qingxin', 'zhenjiang'], |
||||
|
languages: ['zh-CN'] |
||||
|
); |
||||
|
|
||||
|
// 使用SSML格式文本 |
||||
|
await VolcanoSpeech.setTextType(type: TtsTextType.ssml); |
||||
|
await VolcanoSpeech.speakText( |
||||
|
text: '<speak>这是一段<say-as interpret-as="date">2023-10-01</say-as>的语音合成</speak>' |
||||
|
); |
||||
|
|
||||
|
// 设置情感 |
||||
|
await VolcanoSpeech.setEmotion(emotion: 'happy'); |
||||
|
|
||||
|
// 启用情感预测 |
||||
|
await VolcanoSpeech.setEnableEmotionPredict(enable: true); |
||||
|
|
||||
|
// 启用服务端缓存 |
||||
|
await VolcanoSpeech.setEnableCache(enable: true); |
||||
|
|
||||
|
// 监听TTS进度事件 |
||||
|
VolcanoSpeech.ttsProgressEvents.listen((event) { |
||||
|
print('播放进度: ${(event.progress * 100).toStringAsFixed(1)}%'); |
||||
|
}); |
||||
|
|
||||
|
// 复刻音色支持 |
||||
|
await VolcanoSpeech.setEnableVoiceClone( |
||||
|
enable: true, |
||||
|
backendCluster: 'your_cluster_name' |
||||
|
); |
||||
|
``` |
||||
|
|
||||
|
### ASR 语音识别 |
||||
|
#### 一次性识别 |
||||
|
```dart |
||||
|
import 'package:volcano_speech/volcano_speech.dart'; |
||||
|
|
||||
|
// 初始化 |
||||
|
await VolcanoSpeech.initializeAsr( |
||||
|
appId: 'YOUR_APP_ID', |
||||
|
apiKey: 'YOUR_API_KEY', |
||||
|
supportedLanguages: ['zh-CN'], |
||||
|
); |
||||
|
|
||||
|
// 设置识别语言 |
||||
|
await VolcanoSpeech.setAsrLanguage(language: 'zh-CN'); |
||||
|
|
||||
|
// 设置热词（可选） |
||||
|
await VolcanoSpeech.setAsrHotWords( |
||||
|
hotWords: '{"hotwords":[{"word":"火山引擎","scale":2.0}]}', |
||||
|
); |
||||
|
|
||||
|
// 开始一次性识别 |
||||
|
try { |
||||
|
final result = await VolcanoSpeech.recognizeOnce(); |
||||
|
print('识别结果: ${result['text']}, 语言: ${result['language']}'); |
||||
|
} catch (e) { |
||||
|
print('识别出错: $e'); |
||||
|
} |
||||
|
|
||||
|
// 销毁引擎 |
||||
|
await VolcanoSpeech.disposeAsr(); |
||||
|
``` |
||||
|
|
||||
|
#### 连续识别 |
||||
|
```dart |
||||
|
import 'package:volcano_speech/volcano_speech.dart'; |
||||
|
|
||||
|
// 初始化 |
||||
|
await VolcanoSpeech.initializeAsr( |
||||
|
appId: 'YOUR_APP_ID', |
||||
|
apiKey: 'YOUR_API_KEY', |
||||
|
); |
||||
|
|
||||
|
// 监听识别事件 |
||||
|
VolcanoSpeech.asrEvents.listen((event) { |
||||
|
switch (event.type) { |
||||
|
case AsrEventType.sessionStarted: |
||||
|
print('识别会话开始'); |
||||
|
break; |
||||
|
case AsrEventType.sessionStopped: |
||||
|
print('识别会话结束'); |
||||
|
break; |
||||
|
case AsrEventType.recognizing: |
||||
|
print('正在识别: ${event.text}'); |
||||
|
break; |
||||
|
case AsrEventType.result: |
||||
|
print('识别结果: ${event.text}'); |
||||
|
break; |
||||
|
case AsrEventType.volumeChanged: |
||||
|
print('音量: ${event.volume}'); |
||||
|
break; |
||||
|
case AsrEventType.error: |
||||
|
print('识别错误: ${event.errorMessage}'); |
||||
|
break; |
||||
|
} |
||||
|
}); |
||||
|
|
||||
|
// 开始连续识别 |
||||
|
await VolcanoSpeech.startContinuousRecognition(); |
||||
|
|
||||
|
// 检查是否正在识别 |
||||
|
final isActive = await VolcanoSpeech.isContinuousRecognitionActive(); |
||||
|
print('是否正在识别: $isActive'); |
||||
|
|
||||
|
// 停止连续识别 |
||||
|
await VolcanoSpeech.stopContinuousRecognition(); |
||||
|
``` |
||||
|
|
||||
|
#### 长按识别 |
||||
|
```dart |
||||
|
import 'package:volcano_speech/volcano_speech.dart'; |
||||
|
|
||||
|
// 初始化 |
||||
|
await VolcanoSpeech.initializeAsr( |

appId: 'YOUR_APP_ID', |
||||
|
apiKey: 'YOUR_API_KEY', |
||||
|
); |
||||
|
|
||||
|
// 监听识别事件 |
||||
|
VolcanoSpeech.asrEvents.listen((event) { |
||||
|
// 处理事件... |
||||
|
}); |
||||
|
|
||||
|
// 用户按下按钮时开始识别 |
||||
|
onPressed: () async { |
||||
|
await VolcanoSpeech.startListening(); |
||||
|
}, |
||||
|
|
||||
|
// 用户释放按钮时停止识别 |
||||
|
onReleased: () async { |
||||
|
await VolcanoSpeech.stopListening(); |
||||
|
}, |
