KATS

Kaldi-based Automatic Transcription System

Keyword: Speech recognition

Functional Description: KATS is a multipass system for transcribing audio data, and in particular radio or TV shows in French, English or Arabic. It is based on the Kaldi speech recognition tools. It relies on Deep Neural Network (DNN) modeling for speech detection and acoustic modeling of the phones (speech sounds). Higher order statistical language models and recurrent neural network language models can be used for improving performance through rescoring of multiple hypotheses.

News Of The Year: Better acoustic models have been developed for French, English and Arabic languages. An NN-based speech detection module has been included, as well as rescoring with RNN language models.
