A generation apparatusincludes: an argumentative scheme adding unitwhich adds an argumentative scheme with respect to pair data constituted by an input utterance and a counter utterancethat voices a negative opinion with respect to the input utterance and which generates argumentative scheme-added pair data; a generation model learning unitwhich learns a generation model for generating a counter utterance from an input utterance in consideration of the argumentative scheme by using the argumentative scheme-added pair dataas learning data and which generates a learned counter utterance generation model; and a counter utterance generating unitwhich acquires an input utterance of a user and a designated argumentative scheme and which outputs a counter utterance using the counter utterance generation model

Generating device, generating method, and program

The present invention provides a pronunciation error detection apparatus capable of following a text without the need for a correct sentence even when erroneous recognition such as a reading error occurs. The pronunciation error detection apparatus comprises: a speech recognition part that recognizes the speech in speech data based on a speech recognition model for a non-native speaker, and outputs speech recognition results, reliability and time information; a reliability determination part that outputs the speech recognition results with higher reliability than a predetermined threshold and the corresponding time information as the determined speech recognition results and the determined time information; and a pronunciation error detection part that outputs a phoneme as a pronunciation error when reliability for each phoneme in the speech recognition results using the native speaker speech recognition model under a weakly constraining grammar is greater than the reliability of the corresponding phoneme in the speech recognition results using the native speaker acoustic model under a constraining grammar in which the determined speech recognition results are correct for the speech data in a segment specified by the determined time information.
