What Happens to Patient Voice Data After the Call Ends?

Short summary

This article traces the full lifecycle of patient voice data after a phone call ends, from edge encryption through medical ASR processing to PHI redaction. It details how healthcare systems secure audio using TLS 1.3, specialized medical speech recognition, and dual-track redaction across both text and waveforms. The piece highlights that healthcare data breaches average $10.93M per incident, making strict post-call audio processing architecture critical for compliance and patient trust.

• •Patient call audio is encrypted at edge and routed through secure staging before processing
• •Specialized medical ASR engines handle clinical jargon and speaker diarization
• •Dual-track PHI redaction scrubs both transcripts and acoustic waveforms using NER and time-stamped muting
