Question

我正在尝试构建一个类似Alex或Google Home的应用，假设用户说“ Hey MyApp”，应该打开麦克风或应该自动调用与该按钮关联的功能

我已经尝试过API.ai和Ionic TTS插件，但无法使用Ionic中的语音命令找到任何启用本机功能的功能。

Answer 1

是的，您可以使用离子语音识别this

ionic cordova plugin add cordova-plugin-speechrecognition
npm install @ionic-native/speech-recognition

添加模块

然后运行

import { SpeechRecognition } from '@ionic-native/speech-recognition/ngx';

constructor(private speechRecognition: SpeechRecognition) { }

...



// Check feature available
this.speechRecognition.isRecognitionAvailable()
  .then((available: boolean) => console.log(available))

// Start the recognition process
this.speechRecognition.startListening(options)
  .subscribe(
    (matches: string[]) => console.log(matches),
    (onerror) => console.log('error:', onerror)
  )

// Stop the recognition process (iOS only)
this.speechRecognition.stopListening()

// Get the list of supported languages
this.speechRecognition.getSupportedLanguages()
  .then(
    (languages: string[]) => console.log(languages),
    (error) => console.log(error)
  )

// Check permission
this.speechRecognition.hasPermission()
  .then((hasPermission: boolean) => console.log(hasPermission))

// Request permissions
this.speechRecognition.requestPermission()
  .then(
    () => console.log('Granted'),
    () => console.log('Denied')
  )

Answer 2

在构造函数中调用语音识别功能并构建应用程序并安装。

然后说“确定Google打开（您的应用名称）” Google助手打开您的应用程序，语音识别小说将自动触发。

是否可以使用Ionic实施类似“ OK Google”的功能
