Abstract
Official abstract text for this publication.
A system is provided for training an acoustic model for use in speech recognition. In particular, such a system may be used to perform training based on a spoken audio stream and a non-literal transcript of the spoken audio stream. Such a system may identify text in the non-literal transcript which represents concepts having multiple spoken forms. The system may attempt to identify the actual spoken form in the audio stream which produced the corresponding text in the non-literal transcript, and thereby produce a revised transcript which more accurately represents the spoken audio stream. The revised, and more accurate, transcript may be used to train the acoustic model using discriminative training techniques, thereby producing a better acoustic model than that which would be produced using conventional techniques, which perform training based directly on the original non-literal transcript.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for use with a system including a first document containing at least some information in common with a spoken audio stream, the method performed by at least one computer processor executing computer program instructions to perform steps of: (A) determining that text in the first document represents an instance of a concept, comprising determining that the text has a format associated with the concept; (B) identifying, based on the identified text…
