Wanted: Guidance on creating a great audio theme. Maybe based on voice acting or public speaking theory.
Rhapsode still lets you apply CSS styles to your webpages, but since it outputs audio rather than video it supports a different set of CSS properties. This page provides an overview of these properties.
You can use the speak property to determine whether an HTML element should be
read aloud or not, and the speak-as property to determine how it reads digits
and/or punctuation.
Setting speak: never is not the same as setting voice-volume: silent
as the latter still takes up the same ammount of time as it would've to read the text
aloud.
You can use the voice-family attribute to select a voice either by
age/gender/variant or by it's name. Just like font-family this'll make a big
difference to the "look" of your page.
You can alter the voice you choose by varying it's volume, rate, pitch, range, and stress. Doing so helps people pay attention, especially if it reinforces the meaning of your text.
All the speaking style properties provide keywords you can use instead of a number. In which case write a number after a keyword to represent an offset from that keyword.
On either end of your text you can place an audio cue to identify it, and on either end of those you can insert additional silence. If two silences are directly adjacent, the smaller one will be removed.
The inner pauses are called the element's rest and the outer ones
are called it's pause.
The user agent stylesheet, for example, uses audio cues to indicate list bullets and links. And silence functions exactly like whitespace in a visual browser.
Rhapsode supports (some of) the same text generation attributes as visual browsers, namely:
counter-resetcounter-incrementcounter-setcontentThough more may be added in the future.
However unlike visual browsers you can apply the `content` property to the element itself to replace it's own children.
