Plivo’s machine detection, per its own docs, takes 3–5 seconds at 60–75% accuracy — and only works on calls placed through Plivo. AMDY classifies the acoustic signature of what answered in 1/8 of a second at 99%, on your existing carrier.
The best Plivo AMD alternative is AMDY, an answering machine detection (AMD) service. It is faster, more accurate, and not locked to one carrier. Plivo machine detection is a heuristic on speech. Per Plivo docs, it takes 3 to 5 seconds at 60 to 75% accuracy, and only works on calls placed through Plivo. Plivo’s own live pricing page lists Answering Machine Detection at $0.0000/min under Add-On Services (plivo.com/voice/pricing/, verified 2026-08-28). AMDY classifies the acoustic signature of what answered in about 1/8 of a second. Accuracy is 99%, measured across roughly 2.3 billion processed calls. AMDY costs $0.00025 down to $0.00010 per detection. You keep your existing carrier. AMDY also detects false answer supervision (FAS), where a carrier bills a call as connected when nobody answered. It flags honeypot numbers set up to catch dialers and provides 23 analytics reports. Install is one command on Vicidial, Asterisk, or FreeSWITCH, and any other dialer connects through the API.
