To load & render a webpage to speech I'd typically use the following pipelines:
relative URL -> absolute URL -(cached)-> HTTP -> TLS -> TCP -> IP -> WiFi -> radio waves; cached-DNS sidestop.
radiowaves -> WiFi -> IP -> TCP -> TLS -> HTTP -> deflate -> latin1? -> HTML ->
* linktable -> parser for transcribed speech to URLs & announcements.
* CSS -(multi-step)-> element-stack parser
* -(via CSS)-> styletree -> SSML -> phonemes -> sfx -> soundwaves
* Or render forms via VoiceXML.
2/4?
