Patent Searching and Data


Title:
LEARNING DEVICE, SPEECH RECOGNITION ORDER ESTIMATION DEVICE, METHODS THEREFOR, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/163718
Kind Code:
A1
Abstract:
A learning device includes a learning section that learns an error correction model using a set of candidate results for speech recognition with respect to given speech data and a correct text for the speech recognition. The candidate results for speech recognition include a candidate result for speech recognition different from the correct text. The error correction model receives a word sequence of a candidate result for speech recognition and outputs an error correction score indicating the likelihood of the word sequence of the candidate result for speech recognition that takes into account a speech recognition error.
