Lifegence Voiceprint API is a free, open-source, self-hosted REST API for speaker verification and identification. Enrollment records a speaker’s voiceprint; verification compares audio with one enrolled speaker for 1:1 authentication, while identification searches enrolled speakers for a 1:N match. SpeechBrain ECAPA-TDNN produces 192-dimensional voice embeddings. The documented inputs are WAV, MP3, WebM, and OGG recordings lasting 3 to 30 seconds, with 5 to 10 seconds recommended. Docker Compose starts the API with PostgreSQL 16 and pgvector plus Redis 7. Requests use API keys in the X-API-Key header. Enrollment includes consent fields, and a delete endpoint removes associated voiceprint data. The security policy recommends TLS 1.3 in transit, encryption at rest, and treating embeddings as sensitive biometric information. Rate limits are 10 enrollment, 60 verification, and 30 identification requests per minute. The current version has no liveness or anti-spoofing controls and does not guarantee perfect recognition accuracy.
