Speech-to-Text Working on Desktop Web but Not on Mobile Web

[AftabBagwan]

The speech_to_text package works perfectly on the desktop web (tested on Chrome) but fails on mobile web. On mobile web, the recording sound can be heard initially, but the speech input is not recognized. After the initial sound, no further input is processed.

Code snippet

_speechEnabled = await _speechToText.initialize(
    finalTimeout: const Duration(seconds: 60),
    debugLogging: true,
    options: [SpeechToText.webDoNotAggregate],
);

await _speechToText.listen(
    onResult: _onSpeechResult,
    localeId: "en-IN",
    listenMode: ListenMode.dictation,
    listenFor: const Duration(seconds: 60),
    onDevice: true,
);

• On desktop web (Chrome), the plugin works as expected, recognizing speech and triggering the onResult callback.
• On mobile web (Chrome), the recording sound plays initially, but no speech is recognized, and the onResult callback is not triggered.
