Why no TTS/STT shipped in the browser, with all the "intelligence artificial" nonsense shipped, e.g., Gemini?

[guest271314]

It would seem to me that Web Speech API should have been updated within the last decade to be implemented in the browser, rather than using a remote service for Google voice on Chrome and a local service with Speech Dispatcher on Chromium.

Instead Google is advertising Pixel 9 with "built in artificial intelligence".

Surely if I have to disable Gemini search on start up and read "AI" advertisements on every previously empty surface Google can ship its PATTS speech synthesis engine in the browser - and finally provide a way to capture the output as raw PCM in the browser.

Or, as I suspect, is Web Speech API just as dead (https://bugzilla.mozilla.org/show_bug.cgi?id=1474084) as it has been for the past decade?
