AI BriefingNVIDIA Unveils Nemotron 3.5 ASR Supporting 40 Languages
Key point
NVIDIA has unveiled Nemotron 3.5 ASR, a roughly 600-million-parameter model that supports 40 languages in real time.
Details
NVIDIA has unveiled Nemotron 3.5 ASR, a multilingual speech recognition (ASR) model capable of real-time streaming. This model supports 40 language locales with a single checkpoint, and has built-in punctuation and capitalization capabilities.
Key features are as follows:
- Efficient Streaming: Using a Cache-Aware FastConformer-RNNT architecture, it processes audio frames only once without redundant computation, dramatically reducing latency.
- Low Latency: In the Artificial Analysis benchmark, it ranked 2nd in latency among streaming ASR models, demonstrating a balance of high accuracy and low latency.
- Multilingual Support and Auto-Detection: It supports 40 languages including Korean, English, Japanese, and Chinese, and can be configured to either directly specify the input language or have the model automatically detect it.
- Open Weights and Fine-Tuning: Provided as open weights via Hugging Face, allowing users to optimize it through fine-tuning for specific languages, domains, or accents.
This model generates text at a level ready for immediate service application without a separate post-processing step, and can be deployed on one's own infrastructure without API dependency.
