Issue with Web Page Speech Functionality on Mobile

[Mingdr]

Description:

I am trying to use the speech functionality on a web page, which I believe should support speech-to-text conversion via a language button. However, when I click this button on my mobile device, it does not activate the speech feature.

Steps to Reproduce:

Open the web page on a mobile device.
Click on the language button intended for speech-to-text.
Expected Behavior:

The button should activate the speech-to-text functionality.

Observed Behavior:

The speech-to-text feature does not work when the button is clicked on a mobile device.

Additional Information:

I am looking to modify the source code related to this feature. However, I couldn't find the HTML page within the Flask module. Could you please guide me on how to proceed with locating and editing the relevant source code?

Thank you for your assistance!
