Fun-ASR-MLT-Nano-2512

Fun-ASR-MLT-Nano-2512 is an 800M-parameter speech-to-text model from FunAudioLLM, released under the Apache-2.0 license. The reviewed source lists 31 languages (31 explicitly enumerated in our record), and the model is designed for batch transcription, with live use only through a runtime or chunking wrapper. It is a specialist rather than a general pick: its best placement in the common setups we test is #8 of 26, for Japanese live transcription. Use the matcher with your own language and hardware to see where it fits.

Compact 800M multilingual Fun-ASR checkpoint covering 31 listed languages with hotword and ITN controls. The current model card still lists timestamp return and speaker diarization as TODO items; streaming is treated as a toolkit/runtime workflow rather than a proven native streaming architecture.

Hardware and workload fit

These are Speech Model Match's conservative 1–5 editorial ratings, relative to the other 19 reviewed models. They come from model size, official memory guidance and documented runtimes — not from a universal benchmark. How the ratings work.

  • Accuracy (relative): rated 4/5
  • Long recordings: rated 4/5

What to check first

  • CPU-only fit: rated 2/5
  • Apple Silicon fit: rated 2/5
  • Subtitle work: rated 2/5
  • Edge / low-power devices: rated 2/5
  • No native speaker diarization — pair it with a separate diarization pipeline if you need speaker labels
  • Timestamp support is limited or runtime-dependent — test it if you need subtitles

How it ranks in common setups

Ranks come from the same deterministic matcher that runs on the homepage, applied to all 26 reviewed models. They are decision guidance, not accuracy claims.

How to run Fun-ASR-MLT-Nano-2512 locally

Fun-ASR models run through Alibaba's FunASR toolkit. Runtimes below are the ones the official model card or repository documents for this model (checked November 2, 2026).

Install command shown in the official huggingface.co page ↗:

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

Official hardware guidance: The model card's example sets the device to a CUDA GPU or the CPU; no memory figure is published. Source ↗

Whatever runtime you choose, measure speed and accuracy on your own audio with the benchmark tool; results differ a lot between runtimes, precision and hardware.

Before you deploy Fun-ASR-MLT-Nano-2512

A printable checklist built from the facts on this page. Tick it off before putting the model into production.

  1. Language. Confirm your language is in the 31-language list on this page, and test any accents or code-switching you expect.
  2. License. Apache-2.0: Give recipients a copy of the license, keep copyright and attribution notices, carry forward any NOTICE file and mark files you changed. The patent license ends if you start patent litigation over the work. License guide.
  3. Install. Start from the official command: python -m pip install -U "funasr>=1.4.1" (full run notes).
  4. Audio input. Convert a sample of your real recordings to the format the runtime expects before benchmarking.
  5. Hardware. The model card's example sets the device to a CUDA GPU or the CPU; no memory figure is published.
  6. Features you rely on. For Fun-ASR-MLT-Nano-2512, streaming only through a runtime or chunking wrapper; timestamps are not documented; speaker labels need a separate diarization component. Test each one you need with real audio.
  7. Measure. Run 10–20 representative clips, score them with the WER calculator and record speed in the benchmark workspace before you commit.

Common questions

Can I use Fun-ASR-MLT-Nano-2512 commercially?

Permissive license; commercial use is allowed under the listed terms. The listed license is Apache-2.0; read the current license text ↗ before shipping a product, because terms can change. The license guide compares the obligations of all 26 reviewed models.

Does Fun-ASR-MLT-Nano-2512 support real-time streaming?

Not natively. Live use relies on a runtime or chunking wrapper around a batch model, which adds latency and can split words at chunk borders. If live latency is critical, compare it with a native streaming model such as Nemotron 3.5 ASR Streaming 0.6B.

Which languages does Fun-ASR-MLT-Nano-2512 transcribe?

31 listed languages. The full list of 31 explicitly enumerated languages is shown above.

Can Fun-ASR-MLT-Nano-2512 tell speakers apart?

Not natively. Combine it with a dedicated diarization component and evaluate that component separately; the meetings guide covers this workflow.
