Ionic text to speech not works

[devireddyswetha]

Hi All, I am in middle of the application for the text to speech, I used Ionic cordova native text to speech plugin, It works fine when I pass option local:'en-US', In same scenario when I pass local:'ru_RU' for russian, not working. Here i s the code snippet. src/pages/home/home.html

<ion-header>
  <ion-navbar>
    <ion-title>
      Ionic Text To Speech
    </ion-title>
  </ion-navbar>
</ion-header>

<ion-content padding>
  <ion-list>
    <!--Text-->
    <ion-item>
      <ion-label>Text</ion-label>
      <ion-input [(ngModel)]="text"></ion-input>
    </ion-item>
    <!--Rate-->
    <ion-item>
      <ion-range min="1" max="30" step="1" [(ngModel)]="rate">
        <ion-icon small range-left name="remove"></ion-icon>
        <ion-icon small range-right name="add"></ion-icon>
      </ion-range>
    </ion-item>
    <!--Language-->
    <ion-item>
      <ion-label>Language</ion-label>
      <ion-select [(ngModel)]="locale">
        <ion-option value="ru_RU">Russian</ion-option>
        <ion-option value="en-US">English</ion-option>
      </ion-select>
    </ion-item>
    <!--Play text-->
    <button ion-button full (click)="playText()">Play Text</button>
  </ion-list>
</ion-content>

src/pages/home/home.ts

import {Component} from '@angular/core';
import {TextToSpeech} from '@ionic-native/text-to-speech';

@Component({
  selector: 'page-home',
  templateUrl: 'home.html'
})
export class HomePage {
  text: string;
  rate: number;
  locale: string;

  constructor(private tts: TextToSpeech) {
    this.text = 'Initial text';
    this.rate = 1;
    this.locale = 'en-US';
  }

  playText() {
    this.tts.speak({
      text: this.text,
      rate: this.rate / 10,
      locale: this.locale
    })
      .then(() => console.log('Success'))
      .catch((reason: any) => console.log(reason));
  }

}

Please look into it. I want multiple language text to speech.

Thanks.

You have to change from ru_RU to ru-RU
