HLab is a C++ speech recognition engine developed from scratch by Chanwoo Kim under Prof. Bhiksha Raj's supervision. This engine is a Hidden Markov Model (HMM)-based speech recognition engine. It uses the segmental K-means algorithm for training and the viterbi algorithm for decoding. It can handle a trigram language model. This engine can be configured to use either word-model HMMs or phone-model HMMs. This engine has been tested for several speech recognition domains such as Aurora, AN4, etc. The engine is still under development.

This webpage will be updated to include more information about this engine.


The Current source code can be found here.
The Doxygen documentation is availabe here.
