Identifying PHI in a real-time stream
You can identify Personal Health Information (PHI) in either HTTP/2 or WebSocket streams. When you activate PHI Identification, Amazon Transcribe Medical labels the PHI that it identifies in the transcription results. For information about the PHI that Amazon Transcribe Medical can identify, see Identifying personal health information (PHI) in a transcription.
To use the AWS Management Console to transcribe the speech picked up by your microphone and identify any PHI, choose Dictation as the audio input type, start the stream, and begin speaking into the microphone on your computer.
