Creation of a pronunciation dictionary for automatic speech recognition : a morphological approach
Mpho Caselinah Nkosi · 2012
The Pronunciation dictionaries or lexicons play an important role in guiding the predictive powers of the Automatic Speech Recognition (ASR). As the use of automatic speech recognition systems increases, there is a need for the development of dictionaries that cover a large number of inflected word forms to enhance the performance of ASR systems. This paper describes the morphological-driven approach to the creation of a more comprehensive and broadly representative Northern Sotho pronunciation dictionary for ASR systems to augment the existing data-driven methods of dictionary creation. The Preliminary results of an ASR system using morphologically–based rules for a dictionary creation are discussed.
