Speech recognition method e.g. for mobile telephone, identifies which spoken variants of same word can be recognized with analysis of recognition difficulty for limiting number of acceptable variants

摘要

The speech recognition method has several variants for a spoken word generated, with registration during a speech recognition process of which spoken variants of the word can be identified and analysis of the recognition difficulty for the individual speech variants, e.g. for allowing the stored number of variants to be reduced. The different word variants can be generated by phonem replacement, phonem omission and/or phonem insertion, or by addition of noise. Also included are Independent claims for the following: (a) a speech recognition device; (b) a computer program product for a speech recognition method
