Title:
Learning Phonotactic Descriptions by Grammatical Inference
Abstract:
Language resources are important for multilingual speech technology
applications. Manual construction of language resources is typically
time-consuming and requires linguistic expertise. Therefore, alternative
approaches that automatically construct the required language resources
are
preferable. This talk investigates a grammatical inference approach for
automatically constructing finite-state phonotactic resources from
positive
samples of well-formed syllable examples. A set of evaluation
experiments
reveal that automatically constructed phonotactics undergeneralise with
respect to the full set of phonotactic constraints when no linguistic
knowledge is made available. However, by introducing abstract linguistic
structure, sufficiently complete phonotactic models can be automatically
constructed. Also, coverage can be traded off against
overgeneralisation for
different tasks by clustering symbols in a linguistically meaningful
way.
