I want support for CSS Speech

We live in an era where almost every device and platform is capable of talking to you, yet there is no way for authors to design the aural presentation of web content the way they can design the visual presentation with CSS.

Edge, Firefox, and Safari all make it possible for users to listen to content, and extensions bring the same capability to Chrome. Users have limited options — they can change the voice or adjust the speaking rate — but authors have no ability to design the voice experience itself.

This capability exists in the form of SSML on almost every voice-enabled platform, including Amazon Echo, Google Home, and Apple HomePod, where it enables authors to create rich aural experiences by controlling pitch, pauses, emphasis, and pronunciation.

I want the web to close that gap. A proper CSS Speech module — or similar standardized approach — would let authors style audio output with the same care and precision they bring to visual layouts, making web content more expressive and accessible to people who rely on text-to-speech.
