Icefall streaming ASR model for Estonian

This is a streaming end-to-end transducer model for Estonian, trained using Icefall

It is trained on around 800 h of manually transcribed speech from various domains and on about 2500 h of automatically transcribed speech from Estonian TV (mainly news and talkshows)

Serving

To use it on a server for browser-based ASR:

Install Sherpa

Clone this model locally:

git lfs install
git clone https://huggingface.co/TalTechNLP/icefall_pruned_transducer_stateless7_streaming_et

Set SHERPA_ROOT_DIR to the sherpa root directory

Start serving on port 6006:
