Attributes

Attribute	Description
pitch	Specifies the pitch. Pitch is measured in Hz, but units do not need to be specified.
contour	Specifies the pitch contour for the text, by defining the pitch at n points in the speech output. The algorithm for interpolating between the points is platform-specific. Each point n is X_n% of the way through the total length of the contained text. Each pitch_n is any value allowed for the `pitch` attribute. If X<0 or X>100, the point will be ignored. If (0%,pitch₁) and (100%,pitch_n) are not specified, the pitches of the nearest defined points will be copied.
range	Specifies the pitch range. Pitch range is measured in Hz, but units do not need to be specified.
rate	Specifies the speaking rate. Rate is measured in wpm (words per minute), but units do not need to be specified.
duration	Specifies the duration in seconds or milliseconds for the time to read the text.
volume	Specifies the output volume. Volume is a number between 0.0 and 100.0

Note: Relative changes increase/decrease the current value by either the specified amount or percentage: "+/-X[%]",
where X is a floating-point value (ex. "+10", "-5.5", "+15.2%", "-8.0%"). For the pitch and range attributes, relative
changes in semitones are also permitted: "+/-Xst", where X is an integer (ex. "+5st", "-2st").

Limitations/Restrictions

Currently, <enumerate> and  are not supported within <prosody>.
<prosody> is only supported as a child of <foreach> when <foreach> is used within <prompt>.
Refer to your vendor documentation for support details.

Example

To include speech markup tags, insert the SSML tags inside one of the <prompt>, <audio>, <choice>, <enumerate>, or <foreach> (within <prompt>) elements.
