For Fun-ASR-Nano transcription with the Hugging Face API, start with the Transformers 5.17.0 CPU quickstart. No FunASR toolkit or remote Python code is needed.
No local setup? Open the Colab quickstart to transcribe a public sample or upload your own audio in a browser.
Found FunASR useful? Star the project so more builders can find it.
# CPU-only installs can use the default PyPI wheels.
pip install torch torchaudio
pip install funasr
For GPU quickstarts, install the PyTorch and torchaudio wheels that match your
NVIDIA driver from pytorch.org
before installing FunASR. After installation, confirm the GPU is visible:
Only use device="cuda" when this prints True; otherwise use device="cpu"
or reinstall PyTorch with the correct CUDA wheel.
FunASR toolkit GPU example: Fun-ASR-Nano (Chinese, English, Japanese, and Chinese dialect groups and regional accents; the separate native Transformers CPU path is linked above):
from funasr import AutoModel
model = AutoModel(model="FunAudioLLM/Fun-ASR-Nano-2512", device="cuda")
result = model.generate(input="https://isv-data.oss-cn-hangzhou.aliyuncs.com/ics/MaaS/ASR/test_audio/asr_example_zh.wav")
print(result[0]["text"])
For the separate 31-language checkpoint, use
Fun-ASR-MLT-Nano-2512.
Language coverage is checkpoint-specific, so Nano and MLT-Nano should be treated as distinct model choices.
For a CPU-first example with five-language ASR plus emotion and audio-event
tags, use SenseVoiceSmall. The pipeline below combines it with FSMN-VAD and
CAM++ for speaker-aware VAD segments; these are not native speaker outputs of
the SenseVoiceSmall checkpoint.
See the SenseVoice paper,
Hugging Face checkpoint,
and GGUF edge checkpoint.
from funasr import AutoModel
from funasr.utils.postprocess_utils import rich_transcription_postprocess
model = AutoModel(model="iic/SenseVoiceSmall", vad_model="fsmn-vad", spk_model="cam++", device="cpu")
result = model.generate(
input="https://isv-data.oss-cn-hangzhou.aliyuncs.com/ics/MaaS/ASR/test_audio/asr_example_zh.wav",
batch_size_s=300,
)
# The AutoModel pipeline returns VAD segments with speaker ids and timestamps:
for seg in result[0]["sentence_info"]:
print(f"[{seg['start']/1000:.1f}s] Speaker {seg['spk']}: {rich_transcription_postprocess(seg['sentence'])}")
This prints each returned segment's start time in seconds, anonymous speaker
index, and text with SenseVoice tags removed. Text and segment boundaries depend
on the audio and checkpoint; no fixed transcript is asserted here.
CAM++ extracts spk_embedding vectors. AutoModel clusters those embeddings
and assigns speaker indices to VAD segments. Indices are local to a recording,
not known-person identities. See the SDK contract for
the component and result boundaries. Change to device="cuda" only after
verifying a compatible GPU environment as described above.
Scale & deploy the flagship
At scale, accelerate Fun-ASR-Nano with vLLM (batch processing):
from funasr.auto.auto_model_vllm import AutoModelVLLM
model = AutoModelVLLM(model="FunAudioLLM/Fun-ASR-Nano-2512", tensor_parallel_size=1)
results = model.generate(["audio1.wav", "audio2.wav"], language="auto")
FunASR is a toolkit: choose the task, checkpoint, and runtime separately.
Support in one model or adapter does not imply support in every serving backend.
Task
Checkpoint or pipeline
Runtime entrypoint
Important limitation
File transcription with emotion/event tags
SenseVoiceSmall
Python AutoModel, CPU or GPU
Five-language checkpoint; tags do not identify speakers.
LLM-based file transcription
Fun-ASR-Nano
AutoModel; split-engine AutoModelVLLM for the documented GPU path
Base Nano covers zh/en/ja and Chinese dialects/accents; timestamp support depends on checkpoint and path.
Broader multilingual transcription
Fun-ASR-MLT-Nano
Python AutoModel
Separate 31-language checkpoint; do not transfer its coverage to base Nano.
Chunked live transcription
Paraformer-zh-streaming
Streaming SDK or runtime WebSocket service
Use the streaming checkpoint and per-session cache, not an offline checkpoint.
Speaker-aware file transcription
SenseVoiceSmall + FSMN-VAD + CAM++
AutoModel with VAD and embedding clustering
Anonymous indices within a recording, not enrolled-speaker identification.
Joint text, timestamps, and speakers
MOSS-Transcribe-Diarize, third-party OpenMOSS
FunASR adapter or upstream backend in the MOSS guide
Offline, recording-local anonymous labels; no external VAD/speaker pipeline for its unified path.
Native CPU/edge transcription
Fun-ASR-Nano or SenseVoiceSmall GGUF
llama.cpp runtime
Requires matching converted weights; GGUF is not a Python AutoModel checkpoint.
See the Model Zoo and deployment matrix
for checkpoint, interface, and licensing boundaries. Benchmark on your own audio
and hardware before choosing a runtime.
Trying FunASR for the first time? Use the Colab quickstart before setting up a local environment. Choosing a first model? Start with the model selection guide. Planning a switch from Whisper or a cloud ASR provider? Use the migration guide and benchmark example to test representative audio, map features, and roll out safely.
Installation
pip install funasr
git clone https://github.com/modelscope/FunASR.git && cd FunASR
pip install -e ./
Requirements: Python ≥ 3.8. Install PyTorch + torchaudio first (pytorch.org), then pip install funasr.
Model Zoo
This list includes third-party models. OpenMOSS publishes MOSS-Transcribe-Diarize;
FunASR provides an adapter, not ownership of its weights. Its unified path is
offline, with anonymous labels scoped to each recording, not realtime or
known-person identification. Model licenses are separate from the toolkit's MIT license.
Available models: sensevoice (default), paraformer, paraformer-en, fun-asr-nano
Deploy
Start a local SenseVoice CPU service from a fresh directory in a POSIX shell with
Python 3.11. This installs the PyPI release into a separate environment, not this
source checkout. Keep the unauthenticated service on loopback; use the
security guide before exposing it to other clients.
Wait for model download and server startup. In a second terminal, use the same
directory and curl 7.76+ to download a public Chinese audio sample and transcribe it.
The request uses the preloaded model; no fixed transcript or speaker labels are promised.
For offline joint ASR and anonymous speaker labels (moss-transcribe-diarize), prepare the separate environment
in the MOSS service, Docker, Kubernetes, vLLM, SGLang, LocalAI, and FunClip guide →.
It is an alternative service, not another command in the CPU environment. Stop the
CPU service before reusing port 8000. For Nano GPU serving, follow the
pinned split-engine guide and inspect the actual backend logs;
selecting a model does not by itself prove that vLLM was loaded.
# Docker streaming service
docker pull registry.cn-hangzhou.aliyuncs.com/funasr_repo/funasr:funasr-runtime-sdk-online-cpu-0.1.12
CPU / Edge — llama.cpp / GGUF (no GPU, no Python)
Run SenseVoice / Paraformer / Fun-ASR-Nano as a single self-contained binary on CPU and edge devices — this is to FunASR what whisper.cpp is to Whisper, but with ~3× lower CER than whisper.cpp on Chinese. Built-in FSMN-VAD, no Python at runtime.

The Windows Vulkan ZIP uses the system Vulkan loader supplied by the GPU driver;
installing the Vulkan SDK is only necessary when building from source. Both
Vulkan packages currently accelerate SenseVoiceSmall.
Tagged releases provide two Windows CUDA packages. The standard
windows-x64-cuda ZIP targets CUDA architecture 86, while
windows-x64-cuda-blackwell targets architecture 120 (sm_120) for RTX 50 /
Blackwell GPUs. Both ZIPs bundle the required cuBLAS DLLs and use the static MSVC
runtime, so users need a compatible NVIDIA driver but not a separate CUDA Toolkit
installation. CI verifies the architecture and package boundary; it does not prove
inference on physical Blackwell hardware.
Use the RTFx and reproducibility notes
to compare checkpoint/revision, audio set, hardware, batching, warmup, timing
scope, and CER/WER. Offline throughput is not streaming latency. The
migration benchmark example helps measure your own
recordings with the same evaluation scope.
