Description
The <prosody> tag specifies the prosody of the text enclosed within the tag. Prosody refers to the pitch (average frequency), pitch range (difference between the maximum and minimum pitch), rate (words per minute) and volume (loudness) of the speech. If an attribute is not specified, the value remains as it was previously set, it is not reset to a default. The new values apply to all the text enclosed within the tag (unless overridden by a nested <prosody> tag) and then reverts to the previous values when the end tag is reached.
VoiceXML browsers are not obligated to fully implement all speech markup tags, however, a compliant browser must silently ignore any tags it does not support, and should make its best efforts to map any unimplemented mark-up to something similar that is supported.
