## What it is
MASR is an end-to-end Mandarin Chinese automatic speech recognition project built on a gated convolutional neural network (similar to Wav2Letter but using GLU activations) implemented in PyTorch. It includes pretrained models trained on the AISHELL-1 dataset (~150 hours) and supports optional external language models to reduce character error rate.

## Use cases
- transcribe Mandarin Chinese audio to text
- train a Chinese speech recognition model on AISHELL-1
- experiment with convolutional neural networks for ASR
- fine-tune or evaluate a Mandarin ASR model by CER
- integrate Chinese voice input into a Python application
- study how GLU activations affect ASR convergence

## When to choose
- you need offline Mandarin speech recognition in Python with PyTorch
- you want a small, readable reference implementation of convolutional ASR for Chinese
- you want pretrained Chinese ASR models without heavy infrastructure
- you are researching gated convolutional networks for speech recognition

## When to avoid
- you need production-grade accuracy comparable to industrial ASR systems
- you need multilingual or non-Mandarin speech recognition
- you want a maintained project with a clear license for commercial use
- you need streaming/real-time low-latency ASR out of the box
