Inventor: SANADA TORU
IPC: G10L15/08
Filed: 1988-03-17
Abstract: PURPOSE:To facilitate the recognition and the correction by storing the first input voice and subsequently, discriminating which part of the first input voice it is, when a voice of only a corrected part has been reinputted and deciding definitely the recognition of the input voice when the next candidate which has been displayed confirms with the input voice. CONSTITUTION:An input voice is analyzed by an acoustic analyzing part 11, and an acoustic parameter time series is stored in a sentence voice spotting part 13. Subsequently, by comparing said voice with a dictionary by a sentence voice recognizing part 12 by using the acoustic parameter time series outputted from the acoustic analyzing part 11, it is converted to a character sentence, and a result of conversion is displayed on a display part 14. In this state, when an erroneous recognition part is detected, the character sentence which has become the next candidate is displayed on the display part by bringing only its erroneous recognition part to voice input again. In such a way, a user can be released from a complicated operation for instructing an initial end and a terminal of the erroneous recognition part by a cursor on the display part in order to correct an erroneous recognition.
