[分享]HarmonyOS是否有采集语音的能力？

可以使用Core Speech Kit（基础语音服务）集成了语音类基础AI能力，包括文本转语音（textToSpeech）及语音识别（speechRecognizer）能力，便于用户与设备进行互动，实现将实时输入的语音与文本之间相互转换。链接如下：https://developer.huawei.com/consumer/cn/doc/harmonyos-guides-V5/core-speech-introduction-V5

示例代码可参考：

import { BusinessError } from '@kit.BasicServicesKit';
// 设置创建引擎参数
let extraParam: Record<string, Object> = {"style": 'interaction-broadcast', "locate": 'CN', "name": 'EngineName'};
let initParamsInfo: textToSpeech.CreateEngineParams = {
  language: 'zh-CN',
  person: 0,
  online: 1,
  extraParams: extraParam
};
try {
  // 调用createEngine方法
  textToSpeech.createEngine(initParamsInfo, (err: BusinessError, textToSpeechEngine: textToSpeech.TextToSpeechEngine) => {
    if (!err) {
      console.info('createEngine is success');
      // 接收创建引擎的实例
      ttsEngine = textToSpeechEngine;
    } else {
      // 创建引擎失败时返回错误码1003***005，可能原因：引擎不存在、资源不存在、创建引擎超时
      console.error("errCode is " + JSON.stringify(err.code));
      console.error("errMessage is " + JSON.stringify(err.message));
    }
  });
} catch (error) {
  let message = (error as BusinessError).message;
  let code = (error as BusinessError).code;
  console.error(`createEngine failed, error code: ${code}, message: ${message}.`)
}
// 设置回调对象
let speakListener: textToSpeech.SpeakListener = {
  // 开始播报回调
  onStart(requestId: string, response: textToSpeech.StartResponse) {
    console.info('onStart: ' + 'requestId: ' + requestId + ' response: ' + JSON.stringify(response));
  },
  // 合成完成及播报完成回调
  onComplete(requestId: string, response: textToSpeech.CompleteResponse) {
    console.info('onComplete: ' + 'requestId: ' + requestId + ' response: ' + JSON.stringify(response));
  },
  // 停止播报回调
  onStop(requestId: string, response: textToSpeech.StopResponse) {
    console.info('onStop: ' + 'requestId: ' + requestId + ' response: ' + JSON.stringify(response));
  },
  // 返回音频流
  onData(requestId: string, audio: ArrayBuffer, response: textToSpeech.SynthesisResponse) {
    console.log('speakListener onData: ' + ' requestId: ' + requestId+ ' sequence: ' + JSON.stringify(response) + ' audio: ' + audio);
  },
  // 错误回调
  onError(requestId: string, errorCode: number, errorMessage: string) {
    console.error('OnError: ' + 'requestId: ' + requestId + ' errorCode: ' + errorCode + 'errorMessage: ' + errorMessage);
  }
};
// 调用回调方法
ttsEngine.setListener(speakListener);
// 设置播报相关参数
let extraParam: Record<string, Object> = {"queueMode": 0, "speed": 1, "volume": 2, "pitch": 1, "languageContext": 'zh-CN',    "audioType": "pcm", "soundChannel": 3, "playType":1}
let speakParams: textToSpeech.SpeakParams = {
  requestId: '123456',
  extraParams: extraParam
};
// 调用播报方法
this.ttsEngine.speak(this.originalText, speakParams);
