Voice Based User Authentication

via “voice biometric authentication and speaker verification”

[Review](https://theresanai.com/ispeech) - A versatile solution for corporate applications with support for a wide array of languages and voices.

Unique: Combines speaker embedding extraction with configurable threshold management and optional anti-spoofing detection (synthetic speech detection) in a single API, rather than requiring separate services for verification and liveness checking.

vs others: More flexible threshold tuning than Nuance VoiceVault (allows custom FAR/FRR tradeoffs), and supports both text-dependent and text-independent modes unlike some competitors that specialize in only one approach.
