Speech Recognition predefine Language

Ionic Framework ionic-v3
1

Hi there,

I´m trying to use the speech recognition in my ionic3 App. The default-language is en-US, but I want to change it to German (de-DE). I´ve tried a lot to add these Options, but all were ignored without any issue. What is going wrong? Thx a lot! Cheers Marco

I did it like this:

My home.ts

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

constructor(
    public speech: SpeechRecognition,
   ...  
  }

//speech
 
 async hasPermission():Promise<boolean> {
    try {
      const permission = await this.speech.hasPermission();
      console.log(permission);

      return permission;
    } catch(e) {
      console.log(e);
    }
  }

  async getPermission():Promise<void> {
    try {
      this.speech.requestPermission();
    } catch(e) {
      console.log(e);
    }
  }

  listen(): void {
    console.log('listen action triggered');
    if (this.isListening) {
      this.speech.stopListening();
      this.toggleListenMode();
      return;
    }

    this.toggleListenMode();
    let _this = this;
    
    let options = {
       language: 'de-DE'
     }


    this.speech.startListening().subscribe(matches => {
        this.showTextInput = true;
        
        _this._zone.run(() => {
          // matches [0] to avoid multiple suggestions
          _this.textInputDiagnoses = matches[0];
        })
        
      }, error => console.error(error));

  }

  toggleListenMode():void {
    this.isListening = this.isListening ? false : true;
    console.log('listening mode is now : ' + this.isListening);
  }


 
 //end speech

Hey there @marmuel
you have to include options in the startListening method

this.speech.startListening(options).subscribe(maches => {

this must work.

ps. use const instead of let … options also has a type … just import interface and use like this…

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

const options: SpeechRecognitionListeningOptions = {
      language: this.preferredLanguage
 };
