我正在尝试使用 ionic3 进行语音识别插件，但我不断收到此错误

Ionic Native: deviceready did not fire within 5000ms. This can happen when plugins are in an inconsistent state. Try removing plugins from plugins/ and reinstalling them.

我在我的设计（iPhone iOS 10.1）中运行它，使用命令ionic cordova run ios -l

我已经解决了一些SO 问题/离子论坛问题，并尝试重新安装所有插件，按照他们的建议重新安装平台 (ios) + 插件，但仍然没有运气。

以下是我的课

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

@Component({
  selector: 'page-home',
  templateUrl: 'home.html'
})
export class HomePage {

  speechList: Array<string> = [];


  constructor(private speach: SpeechRecognition, public navCtrl: NavController) {

  }

  async getPermission():Promise<void> {
    console.log('abc1');
    try{
      const permission = await this.speach.requestPermission();
      console.log(permission);
      return permission;
    } catch (e){
      console.log(e);
    }
  }

  listenForSpeech():void {
    this.speach.startListening().subscribe(data => this.speechList = data, 
      error => console.log(error)
    )
  }
}
