@llaske, please have look at it. I have respected your constraints by integrating the browser’s native Speech Synthesis / Text to Speech (TTS) API into the codebase for smooth offline functionality using a completely Free/Open-source libraries and services.

Good work 👍
Smart idea to use SpeechSynthesisUtterance that seems widely supported.
We'll be nice to transform the button into a two state start/stop button to be able to avoid restarting from the beginning.
Also the ink color of the button should be white instead of black to be visible on the toolbar.

@llaske Sir, I have transformed the button into a two-state start/stop control and added a white SVG icons to the toolbar.

I've tested on Chromium, it doesn't work. Could you check on your side?

[AliHassan245]

@llaske, SirI usually test on Chromium, and everything is working perfectly on my side. Could you please provide more details about the issue or any specific errors you're seeing? That might help me pinpoint any discrepancies between our environments.

I've got the trace telling that the speech start but there is no sound.

Same issue on Chrome on the same PC (Ubuntu 24.04.2 LTS) thought it works on Firefox.

One other thing: it seems that you retrieve the full text and play it. So when clicking on the pause button, it pause only at the end of the text which it's not a good user experience.
