Bob is a software tool for managing and generating lexicon and pronunciations dictionaries to aid the
development of automatic speech recognition (ASR) systems. The tool is written in Java and is freely
available for noncommercial use under a
Creative Commons licence.
Specifically, it targets lexicon and pronunciation dictionary generation in a way that maintains:
- consistency between spellings in the lexicon and spellings in text corpora used for language modelling
- consistency in use, by non-phoneticians, of a set of phones to describe the pronunciation of words in a language.
Bob is built from the experience, knowledge and procedures
that have been applied successfully in the NIST RT evaluations. It
is flexible enough to enable users to generate lexicons tailored for
specific tasks, including the ability to exclude classes of words (e.g.
removing expletives). The word attribute labels may be customised
and extended to suit the users' needs. It is portable across
languages: the interface is not specific to English and the letter-to-sound
pronunciation predictor can be retrained for any language.
