Vincent Wan, John Dines, Asmaa El Hannani, Thomas Hain · 2008
This paper presents Bob, a tool for managing lexicons and generating pronunciation dictionaries for automatic speech recognition systems. It aims to maintain a high level of consistency between lexicons and language modelling corpora by managing the text normalisation and lexicon generation processes in a single dedicated package. It also aims to maintain consistent pronunciation dictionaries by generating pronunciation hypotheses automatically and aiding their verification. The tool's design and functionality are described. Also two case studies highlighting the importance of consistency and illustrating the use of the tool are reported.
