CSS speak
The CSS speak
property is used to determine whether or not to render text aurally.
The speak
property can be used with speech media to specify whether or not an element should be read out, regardless of its display
settings. For example, you could have some text that's read out on screen readers, even though it doesn't render on visual media (e.g. browsers) due to having display: none
.
Syntax
Possible Values
auto
- Resolves to a computed value of
none
whendisplay
isnone
, otherwise resolves to a computed value ofauto
which yields a used value ofnormal
. none
- Suppresses aural rendering so that the element requires no time to render.
This can be applied against elements you don't want to be spoken. This element will be skipped and there will be no gap (of silence) where it would normally be. If you want a gap of silence, use the voice-volume property.
Note, however, that descendants may override this value and will be spoken.
normal
- The element is rendered aurally (regardless of its
display
value, and thedisplay
andspeak
values of its ancestors). In other words, you can have the text rendered on speech media, even if it isn't displayed on visual media.
In addition, all CSS properties also accept the following CSS-wide keyword values as the sole component of their property value:
initial
- Represents the value specified as the property's initial value.
inherit
- Represents the computed value of the property on the element's parent.
unset
- This value acts as either
inherit
orinitial
, depending on whether the property is inherited or not. In other words, it sets all properties to their parent value if they are inheritable or to their initial value if not inheritable.
