This page is guidance for building well. What you agree to when you use the API is in the terms of service and the privacy policy.
Tell people it is AI
When your app speaks with a Namu voice, let listeners know the voice is generated, the first time they hear it and wherever it matters: health, money, official or legal information. A short line is enough: “This message is read by a computer voice.”Ask before you listen
Recordings sent to/v1/transcribe, /v1/translate and /v1/converse are people’s voices and words. Translation and the voice agent pass the text they work on to Google Gemini through OpenRouter. Tell people their voice is sent to a service to be understood, get their agreement, and do not send recordings of people who did not agree, such as voice notes forwarded from others.
Do not use it to deceive or harm
Do not use the API to:- impersonate a real person, an official or an organisation, or make people believe they hear someone they do not;
- defraud, for example fake calls or messages about mobile money, prizes or debts;
- mislead people about elections, public health or emergencies;
- harass, threaten or shame anyone;
- make decisions about people (health, credit, jobs, justice) from a transcript or translation without a person checking it.
