Speech recognition doesn't work on iOS 13.3

[seemaks]

Hi,
I have created an ionic app which uses this cordova-plugin-recognition for converting speech to text.
It works well on android.
But when I create an ipa file and uploaded it to testflight to be tested via apple store, the testers are not able to record their voice.
It does nothing on trying to record speech nor throws any error.
The code which I used is as follows:
initSpeech() {
this.speechRecognition.hasPermission()
.then((hasPermission: boolean) => {
console.log(hasPermission)
if (!hasPermission) {
this.speechRecognition.requestPermission()
.then(
() => console.log('granted'),
() => console.log('Denied')
)
}
})
}

start() {
// Start the recognition process
this.speechRecognition.startListening()
.subscribe(
(matches: Array) => { this.voicetext = matches[0]; this.mainForm.controls['comments'].setValue(matches[0]); },
(onerror) => console.log('error:', onerror)
)
}

//stop listening for(ios only)
stop() {
this.speechRecognition.stopListening();

}
Please help me with this
