Soniqo Speech
On-device speech AI for Mac, Windows, Linux & Android
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.
Soniqo Speech is the whole speech stack, running on your own hardware — Mac, Windows, Linux, iPhone, and Android — fully on-device:
- Cross-platform, including mobile. Transcription (NVIDIA Nemotron, multilingual + streaming), expressive TTS, voice cloning, speaker-aware diarization, denoising (DeepFilterNet), and full-duplex speech-to-speech (NVIDIA PersonaPlex). Models ship quantized (int4/int8) and tuned for each device's NPU (CoreML on Apple, NNAPI on Android) — the big ones run on a laptop, the light ones on a phone.
- A complete stack, not just models. Underneath sits a voice agent pipeline — turn-taking, interruption/barge-in handling, speech queuing — so you can build an actual conversational agent, not just wire up a transcribe call. Swift, Kotlin, and C++ APIs.
- Speech Studio. A new open-source desktop app for creators: clone a voice from a few seconds of audio, write a script line by line with inline emotion markers like (whispering) or (intense), and synthesize the whole scene locally. macOS to start; Linux and Windows next.
All Apache-2.0, all running on your own machine.
The clip up top is a quick listening test: three voice samples back to back, with no labels — my real voice, a clone made locally by Speech Studio, and a clone made by a cloud service. I can't reliably tell which is which, and that's the point: studio-quality cloning that runs entirely on your own machine.
