Attributes
Attribute | Description |
|---|---|
uri | Required. Specifies the location of the pronunciation lexicon, which is a relative URI or an absolute URI. |
type | Optional. Specifies the media type of the pronunciation lexicon document. Microsoft.Speech currently supports two values. |
Remarks
The lexicon element is an immediate child of the speak element. Multiple lexicon elements can occur in a Speech Synthesis Markup Language (SSML) document. If there are references to multiple lexicons, the order in which they are listed dictates their priority. Speech synthesis (TTS) engines use lexicons of higher priority first when determining which pronunciations to use.
The pronunciation information provided by a lexicon is specific to the single language declared in the xml:lang attribute of the speak element, and is used only for content defined within the enclosing SSML document.
