Anthropic adds an opt-in toggle asking Claude users to share voice recordings for model training

Claude's privacy settings now include an 'Allow us to use your voice data' switch, off by default and separate from the existing text and Claude Code training toggle. Anthropic says the audio helps its models understand and respond to speech and that users can delete their voice data later, though it has not stated a retention period or whether every account sees the option. The move suggests Anthropic is building native speech capabilities, an area where OpenAI and Google currently lead, which matters for anyone planning voice interfaces on Claude.
