FireRedASR2S
A SOTA Industrial-Grade All-in-One ASR System

[Code] [Paper] [Model] [Blog] [Demo]

FireRedASR2S is a state-of-the-art (SOTA), industrial-grade, all-in-one ASR system presented in the paper FireRedASR2S: A State-of-the-Art Industrial-Grade All-in-One Automatic Speech Recognition System. It integrates four modules into a unified pipeline: ASR, Voice Activity Detection (VAD), Spoken Language Identification (LID), and Punctuation Prediction (Punc).

Key Features

FireRedASR2: Supports speech and singing transcription for Mandarin, Chinese dialects/accents, English, and code-switching.
FireRedVAD: Ultra-lightweight module (0.6M parameters) supporting streaming and multi-label VAD (speech/singing/music).
FireRedLID: Supports Spoken Language Identification for 100+ languages and 20+ Chinese dialects.
FireRedPunc: BERT-style punctuation prediction for Chinese and English.

Sample Usage

To use the system, first clone the official repository and install the dependencies. Then you can use the following Python API:

python

from fireredasr2s import FireRedAsr2System, FireRedAsr2SystemConfig

# Initialize the system with default config
asr_system_config = FireRedAsr2SystemConfig() 
asr_system = FireRedAsr2System(asr_system_config)

# Process an audio file (16kHz 16-bit mono PCM)
result = asr_system.process("assets/hello_zh.wav")
print(result['text'])
# Output: 你好世界。

Evaluation

FireRedASR2-LLM achieves 2.89% average CER on 4 public Mandarin benchmarks and 11.55% on 19 public Chinese dialects and accents benchmarks, outperforming competitive baselines including Doubao-ASR, Qwen3-ASR, and Fun-ASR.

Model	Mandarin (Avg CER%)	Dialects (Avg CER%)
FireRedASR2-LLM	2.89	11.55
FireRedASR2-AED	3.05	11.67
Doubao-ASR	3.69	15.39
Qwen3-ASR	3.76	11.85
