Voice AI

AI that handles speech-in / speech-out conversations — typing not required.

In one sentence

Voice AI describes the combination of automatic speech recognition (ASR), language understanding, and speech synthesis (TTS) that lets a user have a spoken conversation with an AI system, hands-free.

When it matters

For installers on scaffolding, technicians in cabs, hosts in noisy kitchens — anywhere typing is impractical.

A real-world example

helpcode Hotline answers your phone number with a voice agent in 1.4 s end-to-end. Eight languages by default; brand technical terms preserved across them.
