Voice agents that
pick up on the first ring.
OneInfer Voice answers, understands, and resolves calls for enterprises at call-center scale — sub-300ms turn latency, thousands of concurrent lines, zero hold music.
The capabilities enterprises actually stress-test.
32 languages
Native-quality ASR and TTS across major world languages and regional accents.
280ms median
Turn-taking latency measured caller-speech-end to agent-speech-start, in production.
50,000+ concurrent
Elastic call capacity that absorbs your busiest hour without a queue.
99.99% uptime
Carrier-grade infrastructure with regional failover and a public status page.
One pipeline, four steps, under a second.
- 01
Listen
Streaming speech recognition
Audio is transcribed as the caller speaks, with barge-in support so they can interrupt the agent naturally.
- 02
Understand
Reasoning over your systems
The agent calls your APIs and knowledge base mid-conversation — scheduling, order status, account lookups.
- 03
Respond
Low-latency speech synthesis
Responses start streaming as audio before the full sentence finishes generating, keeping turns under 300ms.
- 04
Route
Carrier-grade telephony
Calls land over PSTN or SIP with regional points of presence, so audio quality holds up at 50,000 concurrent lines.

What changes when the phone stops being a bottleneck.
Cut scheduling hold time from 6 minutes to zero
“Patients used to wait on hold to reschedule an appointment. Now the agent answers instantly, in whichever language they called in.”
Launched 14 languages in under three weeks
“We'd been trying to hire multilingual claims agents for a year. OneInfer let us cover every language our policyholders speak in one rollout.”
Absorbed a 9x call spike during peak season
“Every December our support line used to buckle. This year concurrency scaled with demand and nobody noticed the difference.”
Composite results across representative enterprise deployments.
Your next caller doesn't need to wait.
