A voice for agents that take real calls.

A phone agent is judged in its first seconds: how fast it answers, whether it hears the caller over the room, whether it reads an order number without tripping. Elbic gives your agent its voice and clean audio, inside the framework you already use.

  1. 91 ms

    Median first audio, Kugel 3

    Answers before the silence gets awkward.

    First audio arrives in 91 ms at the median (Kugel 3). Stream your LLM’s text as it arrives and flush once per turn; the server groups it at sentence boundaries and starts speaking.

  2. Illustration: what reaches your agent with Clarity

    On the line

    • Caller
    • Chatter
    • Train announcement
    • Colleague: “yes”

    Your agent hears

    • Caller
    • Chatter
    • Train announcement
    • Colleague: “yes”

    Hears the caller, not the room.

    Clarity removes background noise in real time and, with a short voice sample of the caller, every other voice too. Voices from a station hall stay out of the transcript, and a colleague’s “yes” no longer counts as the caller’s answer.

  3. 8 kHz

    Telephony output, no resampling

    Ready for the phone line.

    Audio comes out at 8 kHz for telephony with no resampling step, or at 16 to 44.1 kHz for apps and the web. Numbers, codes and pauses are read the way a person on the phone would read them.
