Abstract:     In accordance with the present invention, a method for increasing both dialect precision and usability in speech recognition and text-to-speech systems is described. The invention generates non-linear (i.e. encoded)baseform representations for words and phrases from a pronunciation lexicon. The baseform representations are encoded to incorporate both pronunciation variations and dialectal variations. The encoded baseform representations may be later expanded (i.e. decoded) into one or more linear dialect specific baseform representations, utilizing a set of dialect specific phonological rules.The method comprises the steps of: constructing an encoded pronunciation lexicon having a plurality of encoded and unencoded baseforms; inputting one or more user specified dialects; selecting dialect specific phonological rules from a rule set database; and decoding the encoded pronunciation lexicon using the dialect specific phonological rules to yield a dialect specific decoded pronunciation lexicon.

What is claimed:     1. A method for generating a dialect specific pronunciation lexicon, the method comprising the steps of:
  • a) constructing an encoded pronunciation lexicon, said encoded pronunciation lexicon including a plurality of nonlinear baseforms encoded nonlinearly to include one of dialectal and pronunciation alternatives;
  • b) inputting one or more user specified dialects;
  • c) selecting phonological rule sets from a rule set database responsive to said one or more user specified dialects; and
  • d) decoding the encoded pronunciation lexicon by applying the phonological rule sets to the encoded pronunciation lexicon yielding a dialect specific decoded pronunciation lexicon including a plurality of linear dialect specific baseforms.
