Aural style sheets are for screen readers to read (hence the
auralmedia type you see in the beginning of the style sheet), not for browsers to render. That's why your browser doesn't say anything.They're accessibility tools for people with visual impairments, who need to rely on hearing rather than vision to peruse Web sites.
Aural style sheets are described in the CSS2.1 spec, but have been superseded by the CSS3 Speech Module. It is not known what kind of support exists for either specification, though, as most screen readers in use simply read off what a browser renders and displays.
