The Voice tag supports the following attributes, although not every TTS engine supports every attribute:

  • <gender>

  • <age>

  • <name>

  • <speak>

  • <voice>

  • <xml:lang>

  • <break>

  • <paragraph>

  • <phoneme>

  • <prosody>

  • <say-as>

Each TTS engine has a dedicated page that describes which attributes it supports and how to use them.
