Fun-ASR-MLT-Nano-2512

「简体中文」|「English」

Fun-ASR-MLT-Nano-2512 is the 800M-parameter multilingual checkpoint in the Fun-ASR family. It is trained on hundreds of thousands of hours of multilingual speech and supports 31 languages, with emphasis on East and Southeast Asian languages. For the Chinese, English, and Japanese checkpoint trained on tens of millions of hours, use Fun-ASR-Nano-2512.

What's New 🔥

• 2025/12: Fun-ASR-MLT-Nano-2512 is the multilingual 800M checkpoint, trained on hundreds of thousands of hours of speech and covering 31 languages.
• 2024/7: FunASR is a fundamental speech recognition toolkit that offers a variety of features, including speech recognition (ASR), Voice Activity Detection (VAD), Punctuation Restoration, Language Models, Speaker Verification, Speaker Diarization and multi-talker ASR.

Core Features 🎯

This repository hosts the MLT checkpoint. Its supported-language scope differs from the standard Fun-ASR-Nano checkpoint.

• 31 languages: Covers the languages listed in the model table above, with focused optimization on East and Southeast Asian languages.
• Compact multilingual model: Uses approximately 800M parameters.
• Language control: Accepts the language names shown in the inference example and supports multilingual recognition.
• Context controls: The FunASR inference API exposes hotwords and inverse text normalization (ITN).

Environment Setup 🐍

python -m pip install -U "funasr>=1.4.1"

# Optional: clone the example repo if you want to run the local demo scripts.
git clone https://github.com/FunAudioLLM/Fun-ASR.git
cd Fun-ASR
python -m pip install -r requirements.txt

TODO

• [ ] Support returning timestamps
• [ ] Support speaker diarization
