Grant access once
Browsers require explicit permission for every audio test. Approve the request and reopen the page if you dismissed it previously.
Keep levels consistent
Speak at your normal volume and watch the bar hover between 40% and 70%. If it stays low, raise system gain; if it clips, lower the boost.
