HarmonyOS speechRecognizer服务长语音模式不生效

使用基础语音服务中的speechRecognizer，长语音识别服务，但是目前不生效，到60s后，就会暂停。配置：

let extraParams: Record<string, Object> = {
  "locate": "CN",
  "recognizerMode": "long",
  // "recognitionMode": 0,
  // "vadBegin": 2000,
  // "vadEnd": 3000,
  // "maxAudioDuration": 20000
}
let initParams: speechRecognizer.CreateEngineParams = {
  language: 'zh-CN',
  online: 1,
  extraParams: extraParams
}
