:speech_balloon: An On-Premises, Streaming Speech Recognition System

LibreASR

An On-Premises, Streaming Speech Recognition System

Built with PyTorch and fastai

Example Apps

React Web App	ESP32-LyraT

Quickstart

docker run -it -p 8080:8080 iceychris/libreasr:latest

Head your browser to http://localhost:8080/

Features

• RNN-T network

• Fused language models

• Dynamic Bucketing DataLoader

• Dynamic Quantization

• english, german

• french, spanish, italian, multilingual

• Tuned language model fusion

Performance

Model	Dataset	Network	Params	CER (dev)	WER (dev)
english	1400h	6-2-1024	70M	18.9	23.8
german	800h	6-2-1024	70M	23.2	37.6

While this is clearly not SotA, training the models for longer and on multiple GPUs (instead of a single 2080 ti) would yield better results.

See releases for pretrained models.
