I am building an application using the Web API SpeechRecognition, but onspeechstart and onspeechend listener are not working. https://developer.mozilla.org/ja/docs/Web/API/SpeechRecognition
The version of Safari is 15.0.
The relevant code is as follows. The language is typescript (javascript).
const SpeechRecognitionrecognition = (window as any).webkitSpeechRecognition;
speechRecognizer = new SpeechRecognitionrecognition();
speechRecognizer.onspeechstart = () => {
// Process when the user starts speaking
};
speechRecognizer.onspeechend = () => {
// Processing when speech is finished
};
Are there any settings that are necessary to use these event listeners in Safari? If you know anything about it, I would appreciate it if you could let me know.
