TTS works even if the app is minimised or removed from background

[Nikhil-Daffodil]

Firstly i found that stop() is not working in this , so after google it i found a hack to call start() with empty string.

But another issue that i face is that TTS doe not stop i close the app or minimise it, it will still continue speaking untill it speak the provided string.

` // To Start TTS
startSpeech() {
this.isSpeechActive = true;
this.tts.speak(this.cardData.description)
.then(() => {
console.log('Success');
this.isSpeechActive = false;
})
.catch((reason: any) => {
console.log(reason);
this.isSpeechActive = false;
});
}

//To Stop TTS
stopSpeech() {
this.isSpeechActive = false;
this.tts.speak('')
.then(() => console.log('Success'))
.catch((reason: any) => console.log(reason));
}`
