Title: Speech Recognition Error Correction Modeling Method using Text and Speech Characteristics of Speech Recognition
Inventor: CHUNG MIN HWA
IPC: G10L15/26
Filed: 2020-11-23
Abstract: The present invention relates to a speech recognition error correction modeling method based on sequence-to-sequence (seq2seq), which models errors generated in a voice recognizer by using intonation, rhythmic stress, and acoustic environment features of voice features along with text and includes an encoder and a decoder to apply attention technique, thereby determining response or non-response by using text and sound information extracted from natural speech without inputting a call word. According to the present invention, unlike existing models that attempted to correct errors by using only text information, the speech recognition error correction modeling method using text and voice features uses voice information features to form a robust model by using paralinguistic feature information such as intonation, prosody, and stress contained in voice. In addition, a relationship between voice information and voice recognition error information can be learned by applying the attention technique, and thus it is also possible to learn about a relationship among intonation, stress, rhythm information contained in the voice information, acoustic environments, and voice recognition error text. The method comprises the following steps of: preparing answer text; extracting voice features; extracting voice recognition text; inputting the extracted voice features to the encoder; inputting the voice recognition text to the decoder; setting the answer text as output of the decoder; and modeling a relationship between the voice recognition text and the voice features.
