Key point
NVIDIA supports on-device execution by quantizing ASR, TTS, and speech codecs to GGUF.
Details
Speech recognition (ASR), text-to-speech (TTS), and speech codecs can now be run in local environments via NVIDIA's NeMo-Speech.cpp.
The supported models and components are as follows:
- Magpie-TTS Multilingual
- Nemotron Speech Streaming EN 0.6B
- Nemotron-3.5 ASR Streaming
- Parakeet CTC 1.1B
- Parakeet TDT 0.6B v3
- NanoCodec
The models are quantized in GGUF format, and Hugging Face model cards provide instructions for local execution using NeMo-Speech.cpp. NanoCodec support has also been merged into the project.
