| # π BuzzASR β A Swarm of 100+ Monolingual Speech Recognition Models | |
| **One specialist model per language.** BuzzASR is a suite of **102 monolingual ASR models**, each a fine-tune of | |
| [Whisper-large-v3](https://huggingface.co/openai/whisper-large-v3) specialized to a single language. | |
| The work has been accepted at **EMNLP 2026** Β· built by [Lemn Lab](https://lemn-lab.github.io/buzz-asr/) in collaboration with [EleutherAI](https://huggingface.co/EleutherAI). | |
| ## The idea | |
| Big multilingual models spread themselves thin across hundreds of languages. We asked whether a single specialist, | |
| the same size as Whisper, could beat the giant generalists. It can to a considerable extent :) | |
| ## Highlights | |
| - β Beats Whisper-large-v3 on **89 of 102** languages (FLEURS) | |
| - π **Open-source state-of-the-art** (beats Whisper, Omnilingual 1B/7B, MMS, Qwen3-ASR, Cohere) on **27 languages** | |
| - π Cuts character error rate ~3x on average, and 3.45x across Whisper's 51 worst languages | |
| - π§© Each model is the same 1.55B parameters as Whisper β about 4.5x smaller than the strongest baseline (Omni-7B) | |
| ## A few standouts (combined FLEURS + Common Voice, normalized CER %) | |
| | Language | BuzzASR CER | Whisper zero-shot | Note | | |
| |---|---|---|---| | |
| | [Cantonese](https://huggingface.co/BuzzASR/cantonese) | **13.0** | 36.4 | SOTA β 2x better than the next-best system | | |
| | [Punjabi](https://huggingface.co/BuzzASR/punjabi) | **8.8** | 42.3 | SOTA | | |
| | [Mongolian](https://huggingface.co/BuzzASR/mongolian) | **5.2** | 38.2 | SOTA | | |
| | [Korean](https://huggingface.co/BuzzASR/korean) | **4.6** | 5.7 | SOTA | | |
| | [Amharic](https://huggingface.co/BuzzASR/amharic) | **9.1** | 191 | >20x reduction over Whisper | | |
| ## Find your language | |
| Browse all 102 models in the **Models** tab above, or go to `huggingface.co/BuzzASR/<language>`. | |
| ## Usage | |
| ```python | |
| from transformers import WhisperForConditionalGeneration, WhisperProcessor | |
| model = WhisperForConditionalGeneration.from_pretrained("BuzzASR/mongolian") | |
| proc = WhisperProcessor.from_pretrained("BuzzASR/mongolian") | |
| # the language/task prompt is baked in β just call model.generate(input_features) | |
| ``` | |
