Quick Start

No local setup? Open the Colab quickstart to transcribe a public sample or upload your own audio in a browser.

pip install torch torchaudio
pip install funasr

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="cuda")
result = model.generate(input="https://isv-data.oss-cn-hangzhou.aliyuncs.com/ics/MaaS/ASR/test_audio/asr_example_zh.wav")

# One call returns VAD segments with speaker id + timestamps — render them however you like:
for seg in result[0]["sentence_info"]:
    print(f"[{seg['start']/1000:.1f}s] Speaker {seg['spk']}: {rich_transcription_postprocess(seg['sentence'])}")

Output — structured text with speaker labels, timestamps, and punctuation:

[0.6s] Speaker 0: 欢迎大家来体验达摩院推出的语音识别模型

That's it. One model, one call — VAD segmentation, speech recognition, punctuation, speaker diarization all happen automatically.

LLM-powered ASR: Fun-ASR-Nano

For highest accuracy across 31 languages (including Chinese dialects), use Fun-ASR-Nano — an LLM-based ASR combining SenseVoice encoder with Qwen3-0.6B decoder:

from funasr import AutoModel

model = AutoModel(model="FunAudioLLM/Fun-ASR-Nano-2512", vad_model="fsmn-vad", device="cuda")
result = model.generate(input="https://isv-data.oss-cn-hangzhou.aliyuncs.com/ics/MaaS/ASR/test_audio/asr_example_zh.wav")

With vLLM acceleration (16x faster, 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")

Deploy as API server: funasr-server --device cuda → OpenAI-compatible endpoint at localhost:8000

Use with AI agents: MCP Server for Claude/Cursor · OpenAI API for LangChain/Dify/AutoGen

Why FunASR?

	FunASR	Whisper	Cloud APIs
Speed	170x realtime	13x realtime	~1x realtime
Speaker ID	✅ Built-in	❌ Needs pyannote	✅ Extra cost
Emotion	✅ Happy/Sad/Angry	❌	❌
Languages	50+	57	Varies
Streaming	✅ WebSocket	❌	✅
vLLM Acceleration	✅ 2-3x faster	❌	N/A
Self-hosted	✅ MIT license	✅ MIT license	❌ Cloud only
Cost	Free	Free	$0.006/min+
CPU viable	✅ 17x realtime	❌ Too slow	N/A

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.

Benchmark

184 long-form audio files (192 min). Full report →

Model	GPU Speed	CPU Speed	vs Whisper-large-v3
SenseVoice-Small	170x realtime	17x realtime	🚀 13x faster
Paraformer-Large	120x realtime	15x realtime	🚀 9x faster
Whisper-large-v3-turbo	46x realtime	❌	3.4x faster
Fun-ASR-Nano	17x realtime	3.6x realtime	1.3x faster
Whisper-large-v3	13x realtime	❌	baseline

Key takeaway: FunASR models run on CPU faster than Whisper runs on GPU.
