say

The say command is used to send synthesized speech to the remote party. The text provided may be either plain text or may use SSML tags. jambonz supports a large number of speech vendors out of the box (see list below), and you may add others via the custom speech API.

{
  "verb": "say",
  "text": "hi there!",
  "synthesizer" : {
    "vendor": "google",
    "language": "en-US"
  }
}
