Note
Speech-to-text audio transcription is in limited early release and must be enabled by Vivox. For pricing information and to enable this service for your organization, contact your sales representative.
The Vivox SDK reports transcribed messages in IChannelSession::EventTranscribedMessageReceived events. Note that this event is different from EventTextMessageReceived, which is used for in-channel messages that are exchanged by participants.
Transcribed messages that are not stored in a text channel are only visible to users who have speech-to-text transcription enabled. Channel sessions that are only connected to text do not receive transcription events because there is no speech to transcribe. If audio capability is added to a channel with IChannelSession::BeginSetAudioConnected(), then transcription, if previously enabled, starts automatically.
If your organization does not have speech-to-text transcription enabled, then 
IChannelSession::EventTranscribedMessageReceived
events do not occur.
