離子4語音識別

Question

我正在嘗試使用語音識別，但我不斷收到錯誤這是我的頁面

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

@Component({
    selector: 'app-home',
    templateUrl: 'home.page.html',
    styleUrls: ['home.page.scss'],
})
export class HomePage {

    constructor(private speechRecognition: SpeechRecognition) {
        this.speechRecognition.requestPermission()
            .then(
                () => console.log('Granted'),
                () => console.log('Denied')
            );
    }

    record() {
        const options = {
            language: 'da-DK',
            prompt: '',      // Android only
            showPopup: true,  // Android only
            showPartial: false
        };
        this.speechRecognition.startListening(options)
            .subscribe(
                (matches: Array<string>) => console.log(matches),
                (onerror) => console.log('error:', onerror)
            );
    }

}

有了這個我得到以下錯誤：

    RROR in src/app/home/home.page.ts(12,32): error TS2339: Property 'requestPermission' does not exist on type 'SpeechRecognition'.
[ng]     src/app/home/home.page.ts(26,32): error TS2339: Property 'startListening' does not exist on type 'SpeechRecognition'.

我使用離子 4

Answer 1

在導入時使用ngx import { SpeechRecognition } from '@ionic-native/speech-recognition/ngx';

也許你也應該作為提供者導入。
