Build voice agents on a complete on-device speech stack: ASR (NVIDIA Nemotron, multilingual + streaming), TTS, voice cloning, diarization, denoising, and full-duplex speech-to-speech (NVIDIA PersonaPlex) — plus a voice agent pipeline for turn-taking, interruptions, and queuing. Runs on Mac, Windows, Linux, and mobile (iPhone + Android), with NPU-optimized inference (CoreML, NNAPI). Swift, Kotlin, and C++ APIs. Plus Speech Studio, a desktop voice-cloning app for creators. Apache 2.0, on-device.
One Swift package for every speech capability you'd normally rent from a cloud API — transcription, expressive TTS, voice cloning, speaker-aware diarization, denoising, full-duplex speech-to-speech — running on-device on Apple Silicon. brew install soniqo/tap/speech ships a CLI, a local HTTP server, and the Swift API. Apache 2.0. No cloud, no keys, no per-minute bills.
