为此，您需要使用cordova-diagnostic-plugin检查当前的麦克风授权状态，如果授权被拒绝，则再次请求授权。

import { Diagnostic } from '@ionic-native/diagnostic/ngx';

constructor(private diagnostic: Diagnostic) {}

    async requestMicrophoneAuthorization() {
// Check the current microphone authorization status
let authorizationStatus = await this.diagnostic.getMicrophoneAuthorizationStatus();
    if (authorizationStatus === this.diagnostic.permissionStatus.DENIED_ALWAYS) {
    // If the authorization has been denied always, we need to ask the user to grant
    // microphone permission again.
    try {
    // Request microphone authorization
        authorizationStatus = await this.diagnostic.requestMicrophoneAuthorization();
    console.log('Microphone authorization status: ', authorizationStatus);
    } catch (error) {
        console.error('Error requesting microphone authorization: ', error);
    }
   }
  }
