  • What's in the SDK


    TrulyHandsfree (wake words and commands), TrulyNatural Lite (LVCSR), and TrulyNatural STT (transformer transcription) — three variants, one API. Compare features, supported platforms, and host requirements.

    Reference overview

  • Get started


    Install the SDK and try wake words, LVCSR, or STT with the command-line tools (snsr-eval, snsr-edit). When you are ready to embed, build a Session API sample for your platform — embedded, mobile, or desktop.
