## PHI Redaction Now Available for Batch and Streaming Speech-to-Text

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:**

```bash
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'
```
