Introduction

   Hands-free computing is important because it is useful to both   able and disabled users. Speech recognition systems can be   trained to recognize specific commands and upon confirmation   of correctness instructions can be given to systems without   the use of hands. This may be useful while driving or to an   inspector or engineer in a factory environment. Likewise   disabled persons may find hands-free computing important in   their everyday lives. Just like visually impaired have found   computers useful in their lives.






Research

 Acoustic Modeling

 An acoustic model is created by taking audio recordings of speech,  and their text transcriptions, and using software to create statistical  representations of the sounds that make up each word.

 Key-word Spotting

 Keyword spotting is an efficient approach for search of relevant  recordings in databases recorded unconstrained speech.
