Abstract:
1. A method for synchronizing words in an input text of a speech with a recording of the speech, comprising: performing, by a processor of a computer system, speech recognition of input speech data representing the speech, by comparing the input speech data with pronunciation speech data associated with the input text, to generate a recognition text comprising recognized words of the input text; determining, by the processor of the computer system, by comparing the input text with the recognition text, an erroneous recognition text comprising words of the input text not matching respective words of the recognition text; generating, by the processor of the computer system, synthetic speech data corresponding to the erroneous recognition text; computing, by the processor of the computer system, from the input speech data to which each word of the synthetic speech data corresponds, ratio data comprising a ratio of a pronunciation time in the input speech data of each word of the erroneous recognition text to a pronunciation time in the input speech data of each other word of the erroneous recognition text; and determining, by the processor of the computer system, based on the computed ratio data, an association between each word of the erroneous recognition text and a time to reproduce the input speech data corresponding to said each word of the erroneous recognition text.
