CSS Gehoorverwysing _
Gehoorstylblaaie
Gehoorstylblaaie gebruik 'n kombinasie van spraaksintese en klankeffekte om die gebruiker na inligting te laat luister, in plaas daarvan om inligting te lees.
Gehooraanbieding kan gebruik word:
- deur blindes
- om gebruikers te help om te leer lees
- om gebruikers wat leesprobleme het, te help
- vir tuisvermaak
- in die kar
- deur drukgestremde gemeenskappe
Die gehooraanbieding verander die dokument na gewone teks en voer dit na 'n skermleser ('n program wat al die karakters op die skerm lees).
'n Voorbeeld van 'n gehoorstylblad:
h1, h2, h3, h4
{
voice-family: male;
richness: 80;
cue-before: url("beep.au")
}
Die voorbeeld hierbo sal die spraaksintetiseerder 'n klank laat speel en dan die koptekste in 'n baie ryk manstem uitspreek.
