Abstract

An embodiment of the present invention provides an adaptive correction method for a user's personal pronunciation dictionary model. The method includes: establishing an initial personal pronunciation dictionary model, receiving a user's correction of an erroneous word in the model recognition result, and comparing the confidence in the acoustic score of the erroneous word with the preset confidence when the correction is a matching replacement word. Determine whether there is a pronunciation problem; determine whether the pronunciation relationship between the wrong word and the replacement word belongs to the regular fuzzy sound rule, compare the number of historical corrections, and if it belongs, adjust the pronunciation weight of the same pronunciation as the wrong pronunciation in batches. If it does not belong, adjust it separately Mispronunciation weights, based on the adjusted weights, adaptively correct the individual pronunciation dictionary model. The embodiment of the present invention also provides a system for self-adaptive modification of the user's personal pronunciation dictionary model. The embodiment of the present invention effectively handles recognition errors caused by inaccurate pronunciations of users, and batch corrections can be performed on a class of regular wrong pronunciations.

Description

Technical field [0001] The present invention relates to the field of speech recognition, and more particularly to an adaptive correction method and system of a pronunciation dictionary model of a user. Background technique [0002] In order to make speech recognition more user-friendly, in speech recognition, in addition to using the shared language model, the individual language model for each user is added. This personal language model can be based on the user's past input, or the model obtained by the user-defined word table, in the actual speech recognition, the score of the language model is usually interpolated by the shared language model and the individual's language model. . [0003] In implementing the present invention, the inventors have discovered at least the following problems in the relevant techniques: [0004] This technique is valid based on the ASR (Automatic Speech Recognition, Automatic Speech Recognition) system based on the user's personal language model, ...
