View NeMo Speech Tool Page →NeMo Speech is NVIDIA's open-source generative AI framework for speech, and it is quickly becoming the default choice for teams that need production-grade automatic speech recognition (ASR) and text-to-speech (TTS) without building everything from scratch. With more than 17,000 GitHub stars and an Apache-2.0 license, it is free to use, modify, and deploy — even commercially.
Why NeMo Speech?
NeMo gives you pretrained, state-of-the-art models plus the training toolkit to fine-tune them on your own data. The speech stack covers the full pipeline: Parakeet for high-accuracy ASR, Canary for multilingual transcription and translation, and FastConformer backbones for low-latency real-time inference.
| Component | Purpose |
|---|---|
| Parakeet | High-accuracy ASR models |
| Canary | Multilingual ASR + translation |
| FastConformer | Real-time inference backbone |
| TTS | Text-to-speech with vocoders |
Key features
- Pretrained models ready for inference out of the box
- Fine-tuning scripts for domain-specific speech data
- Multilingual support across dozens of languages
- Deployment via Docker and NGC containers
