Abstract

A study into the practical implementation of speech recognition for the purposes of data capturing within Telkom is described. Specific tests on a selected continuous speech recognition system are highlighted. The system chosen for the tests was locally produced and was trained using a male database of speech samples. The tests were aimed specifically at testing the accuracy and adaptability of the system. Typical results obtained, substantiate the need for training a recognition system with either male or female participants, on a numerical 10 word vocabulary. The results obtained for the male participants was 95% on average whereas the female average was 83%. The difference between accuracy and system throughput is also discussed leading to conclusions as to the suitability of continous speech recognition for this application
