Voice Service

Facephi Voice Service is a Rest API service to which audio files can be sent for processing and to obtain the result of the voice recognition process. The service offers a service to register (enroll) a new voice, and another to authenticate a voice.

The product is aimed at speaker verification and voice liveness detection. It is based on the use of a voice template, a text string that contains the biometric information of the voice. This voice template can be used to authenticate voices in the future.

Optional JWT authentication can be enabled at startup from config.json or through the environment variables FACEPHI_VOICE_REST_AUTH_*. When JWT is enabled, GET /api/v1/version and GET /api/v1/health remain public, while protected endpoints require a valid JWT. The JWT startup configuration is never exposed through GET /api/v1/config nor can it be modified through POST /api/v1/config.

The supported audio formats are:

• WAV

• MP3

• Opus/OGG

• AAC

• WMA

• PCM ulaw and mulaw

• FLAC

• ALAC (mov)

• MP4

• AIFF
