VoiceXML for PowerMedia XMS will follow the Speech Server Markup Language (SSML) 1.0 standard for speech control interface. It will have its own SSML processor to interpret speech tags and provide to VoiceXML application a standard way to control aspects of speech such as pronunciation, volume, pitch, and rate.
This release of PowerMedia XMS will only support a subset of the SSML 1.0 standard. Although all elements will be parsed and processed, the only SSML element to be integrated with the PowerMedia XMS media engine is the <audio> element. It specifies the audio files to be played. For TTS enabled application, all SSML commands will be transferred as-is to the speech server via the Media Resource Control Protocol (MRCP) interface. Refer to the speech vendor specification for the SSML support coverage.
