What is answering machine detection?

Answering Machine Detection (AMD) is a feature of the Telnyx Voice API that determines whether a machine (voicemail answering machine) or a human answered the call.

Premium AMD with Telnyx

Our premium Answering Machine Detection uses advanced speech recognition technology and a machine learning process to achieve exceptional accuracy in determining whether the call has been connected to a live person or an answering machine.

Get The Accuracy You Need

Standard Detection

Our standard Answering Machine Detection algorithm uses voicemail tone detection to identify whether you call is answered by a human or a machine. Detection accuracy can be tested and refined using configurable time-windowing parameters.

Premium Detection

Premium Answering Machine Detection uses advanced Voice Activity Detection (VAD) to make more granular classifications of the call result, identifying silence, an answering machine greeting, a human residence greeting, or a human business greeting.

Ensure your message is delivered with confidence
