This paper compares the recognition accuracy of a phoneme-based automatic speech recognition system with that of a grapheme-based system, using Afrikaans as case study. The first system is developed using a conventional ...

Grapheme-based speech recognition systems are faster to develop but typically do not reach the same level of performance as phoneme-based systems. In this paper we introduce a technique for improving the performance of ...

We report on the development of speech-recognition systems that are able to perform accurate recognition on mediumvocabulary tasks (i.e. tasks that require distinctions between approximately 200 different terms). We are ...
