Why on-device

Speech AI, built for the device

  • Privacy by design

    Process supported speech workloads locally, reducing the need to send audio to remote servers.

  • Low-latency speech

    Reduce network round trips by processing speech directly on supported devices.

  • Lower cloud costs

    Reduce per-request cloud processing for speech workloads handled on-device.
