To activate the speech synthesis feature with a message, you must click a button for it to work

The issue with the code snippet below is that the function "window.speechSynthesis.speak(msg)" does not produce any sound output unless the button is clicked first. Only after clicking the button, the "Hello" message works as intended. Any attempts to call "window.speechSynthesis.speak(msg)" before pressing the button result in no audible feedback.

Various attempts have been made to initialize speechSynthesis before calling "Hello." However, none of these methods have been successful. Even though it seems like initialization should occur properly, it appears that speechSynthesis only initializes correctly when triggered by the button press.

The configuration of SpeechSynthesisUtterance remains consistent whether called via the button press or timeout. While this configuration functions correctly when triggered by the button, it fails to work anywhere else until activated by the button.

What could be causing this issue?

The cause of this issue could potentially be linked to the specific web browser being used... It has come to our attention that recent updates in popular browsers such as Firefox and Chrome now have privacy policies in place which restrict access to audio unless prompted by user interaction, such as clicking a designated button...
