Sub-second latency

Conversations with no awkward pause

The thing that gives an AI voice agent away is the pause. CallIntel runs a native speech-to-speech tier that responds in under a second, lets callers interrupt naturally, and knows when a caller has actually finished speaking, so the conversation feels like a conversation.

How it works

  1. Choose your tier

    Run the native speech-to-speech tier for the lowest latency, or the cascaded tier when cost is the priority for a given line.

  2. Tune turn-taking

    Set how the agent handles interruptions and pauses so it matches the pace of your callers and the kind of calls you take.

  3. Go live and listen

    Callers get sub-second, interruptible replies with natural turn-taking, and you can review how conversations flow in the transcripts.

Why it wins

What you get

  1. Replies in under a second

    The native speech-to-speech tier responds fast enough that callers stop noticing they are talking to software and just have the conversation.

  2. Interrupt it like a person

    Callers can talk over the agent to correct or redirect it, and the agent stops and listens, the way a person would, instead of talking past them.

  3. Knows when you are done

    Smart end-of-turn detection means the agent waits when you pause mid-thought and replies when you have actually finished, so it neither cuts you off nor leaves dead air.

What it does

Capabilities

  • Native speech-to-speech tier for sub-second response
  • Natural barge-in so callers can interrupt and redirect
  • Smart end-of-turn detection that waits through mid-thought pauses
  • A cascaded tier available when cost matters more than raw speed
  • Turn-taking you can tune to the pace of your callers
  • Consistent responsiveness across languages and call types
Before CallIntel

There is a beat of silence after every caller stops talking. The agent talks over people, or cuts them off, and callers quickly realize it is not a person.

With CallIntel

Replies land in under a second, callers can interrupt and be heard, and the agent waits through natural pauses, so the call flows like a real conversation.

A voice agent fast enough, and natural enough at taking turns, that callers stop wondering whether they are talking to a person.

Frequently asked questions

How fast does the agent respond?
The native speech-to-speech tier responds in under a second, which is fast enough that the usual robotic pause disappears.
Can callers interrupt the agent?
Yes. Natural barge-in lets a caller talk over the agent to correct or redirect it, and the agent stops and listens.
What is the cascaded tier for?
It is an alternative tier you can use when cost matters more than the absolute lowest latency for a given line.
How does end-of-turn detection work?
The agent distinguishes a mid-thought pause from a finished turn, so it waits when you are still talking and replies when you are done.
