Introduction

This repository builds upon the incredible work of icefall, integrating and extending its features to provide a convenient and controllable framework for model training and testing. The base line code use Zipformer with Eden scheduler and ScaledAdam optimizer. Feel free to customize the provided configuration file and layer modules to suit your specific model and training requirements.

How to use
