Getting started with answering machine detection

Rather than detecting voicemail by listening for a beep, Plivo by default detects voicemail using heuristic algorithms that are based on tone of voice, the speed of spoken words, and other factors. This detection usually takes three to five seconds with an accuracy of 60-75%, which is on par with industry standards. You can enable answering machine detection (AMD) using our Call object with the machine_detection and machine_detection_time parameters. See our documentation on answering machine detection.
