We're excited to announce that PHI (Protected Health Information) redaction is now available for both batch (pre-recorded) and streaming speech-to-text.

redact=phi

You can now redact protected health information using the new phi parameter, which redacts the following entity types: condition, drug, injury, blood_type, medical_process, and statistics.

Key features:

• Batch support: Available for all pre-recorded audio transcription
• Streaming support: Available for real-time streaming transcription
• Language support: Follows existing redaction language support (all languages for hosted batch, English only for streaming)
• Combine with other redaction options: Use multiple redaction parameters together (e.g., redact=phi&redact=pci)

Example usage:

curl \
  --request POST \
  --header 'Authorization: Token YOUR_DEEPGRAM_API_KEY' \
  --header 'Content-Type: audio/wav' \
  --data-binary @youraudio.wav \
  --url 'https://api.deepgram.com/v1/listen?redact=phi'
