# MedicalScribeChannelDefinition
<a name="API_streaming_MedicalScribeChannelDefinition"></a>

Makes it possible to specify which speaker is on which channel. For example, if the clinician is the first participant to speak, you would set the `ChannelId` of the first `ChannelDefinition` in the list to `0` (to indicate the first channel) and `ParticipantRole` to `CLINICIAN` (to indicate that it's the clinician speaking). Then you would set the `ChannelId` of the second `ChannelDefinition` in the list to `1` (to indicate the second channel) and `ParticipantRole` to `PATIENT` (to indicate that it's the patient speaking). 

If you don't specify a channel definition, HealthScribe will diarize the transcription and identify speaker roles for each speaker.
