Modular Speech Technology

Automated Speech Recognition (ASR)

Our flagship product easily recognizes a wide variety of languages and dialects. Accuracy and performance are foundational in LumenVox’s dynamic ASR engine with its end-to-end Deep Neural Network (DNN) architecture.

Call Progress Analysis

Keep your communication clear with Call Progress Analysis (CPA). With high payload delivery, our CPA is also able to recognize the difference between consumer and enterprise machines as well as SIT and busy network tones for a far more effective way to get your messages delivered. Our CPA technology can most accurately determine whether the call has been connected to a live person or to an automated recording system, only beginning the message after a live human pause or an answering machine tone is heard.

Voice Biometrics

Effortlessly authenticate over remote channels, improving both customer experience and security through analyzing your customer’s voice pattern.
