Abstract
The invention relates to a method and apparatus for generating phrasal transcriptions. The invention provides generating a group of word transcriptions for each vocabulary item in an orthographic phrase. According to a first embodiment, the invention further provides permuting the word transcriptions to generate a plurality of phrasal transcriptions and computing a score for each phrasal transcription in the plurality of phrasal transcriptions. The set of phrasal transcriptions is then selected from the plurality of phrasal transcriptions at least in part on a basis of the score data elements and stored in a format suitable for use by a speech recognition dictionary. As a variant, the phrasal transcriptions may be released in a format suitable for use by a speech synthesizer. According to a second embodiment, the invention further provides permuting the word transcriptions to generate the set of phrasal transcriptions, the permuting being characterized by yielding a higher likelihood of variability between the word transcriptions associated to a common vocabulary item among the set of phrasal transcriptions than a permuting rule using an outer-product procedure. The method further provides a computer readable medium comprising a program element operative to implement a method for generating a set of phrasal transcriptions.
