The transcribe verb is used to send real time transcriptions of speech to a web callback.

The transcribe command is only allowed as a nested verb within a dial or listen verb. Using transcribe in a dial command allows a long-running transcription of a phone call to be made, while nesting within a listen verb allows transcriptions of recorded messages (e.g. voicemail).
