# How to Anonymize Voice Recordings with Claude

Claude approaches voice anonymization as an analytical conversation in your terminal. Describe your anonymization requirements and Claude will ask follow-up questions about the intended use case, desired naturalness level, and whether the content will be distributed publicly. This back-and-forth ensures the transformation is strong enough to protect identity without degrading intelligibility.

## Setup

claude mcp add toolrouter -- npx -y toolrouter-mcp

## Steps

1. Connect ToolRouter: claude mcp add toolrouter -- npx -y toolrouter-mcp
2. Ask Claude: "Anonymize this voice recording using voice-transformer -- change the voice to protect the speaker identity"
3. Claude transforms the voice while preserving the spoken content
4. Verify the words are still clear and the voice is unrecognizable
5. Download the anonymized recording for safe distribution

## Example Prompt

```
Anonymize this interview recording. The speaker needs to be unidentifiable by voice but the content must remain perfectly clear and intelligible.
```

## Tips

- Ask Claude to apply multiple transformation parameters for stronger anonymization
- Test the anonymized audio with someone who knows the speaker to verify it is unrecognizable
- Ensure the transformed voice still sounds natural, not robotic or obviously processed
