wantt / RapidASR

A Cross platform implementation of Wenet ASR inference. It's based on ONNXRuntime and Wenet. We provide a set of easier APIs to call wenet models.

RapidASR: a new member of RapidAI family.

Our vision is to offer an out-of-box engineering implementation for ASR.

A cpp implementation of recognize-onnx.py in Wenet-asr in which it implements the inference with ONNXRuntime. For a version of pure CPP code, we need to do a bit of work to rewrite some components.

Special thanks to its original author SlyneD.

Less is more. Less dependency, more usability.

Just offline mode, not support stream mode, aka separate files can be recognized.

Supported modes:

• CTC_GREEDY_SEARCH
• CTC_RPEFIX_BEAM_SEARCH
• ATTENSION_RESCORING

Progress:

• Python
• Linux
• Mac
• Android
• Windows

Models

The model is original from https://github.com/wenet-e2e/wenet/tree/main/examples/wenetspeech/s0 and tested with recognize-onnx.py.
