Ionic text to speech not works


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

Ionic Text To Speech Text Language Russian English Play Text src/pages/home/home.ts

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

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() {
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. (edited)
