Sing

Sing gets your agent talking sooner.

Sing starts the agent’s voice on the first words of the reply instead of waiting for the whole of it, so the first word comes sooner. It runs beside the voice you already use.

ReleaseOct 31, 2026

The caller hears the first word sooner.

The voice you run today keeps speaking the reply. It just starts on the first words instead of waiting for the last.

  • The voice starts early

    Sing starts the agent’s voice on the first words of the reply, instead of waiting for the whole sentence.

  • Your voice, your sound

    Sing works with the voice you already run. What the caller hears is still that voice.
