Why the models rank PolyAI — on best voice agent platforms for customer support
“Best overall for large-scale customer support: exceptionally natural voice interaction, strong intent handling, multilingual service, transactional workflows, warm escalation, and proven contact-center deployment; near-tied with Cognigy, but voice specialization earns the edge”
Why the models rank Retell AI — on best voice agent platforms for customer support
“Purpose-built for support call automation rather than generic voice infra — batch/inbound call handling, IVR navigation, warm transfer, post-call analysis, and prebuilt telephony/SIP plus CRM and Zendesk-style integrations make it the fastest path from "we get 5k support calls a month" to a working deployed agent; transparent per-minute pricing and strong latency/interruption handling suit the typical mid-market support team this category serves.”
