Failed iOs

[vasquezdennisalon]

I am working the application on ios but I install the library I add all the dependencies and try to do the following

this.speechRecognition.hasPermission ().then ((hasPermission: boolean) => {
        if (! hasPermission) {
                 this.speechRecognition.requestPermission ().then (
                            () => console.log ('Granted'),
                            () => console.log ('Denied')
                 )
        }
});

it does not show the alert to activate voice and microphone recognition and when I start it, it also does not take any action
