Abstract: a hearing assistance apparatus includes: a speech recognition information generation unit executes speech recognition processing on first speech information to infer one or more words from the first speech information, and generating speech recognition information by, for each of the one or more inferred words, associating word information representing the inferred word with second speech information corresponding to the inferred word; a first division unit divides a first character string formed by the one or more words into individual words or individual characters using the word information to generate second character string information representing a second character string; and a display information generation unit generates display information for displaying, on a display device, the second character string and a division position indicating a position at which the first character string was divided.

Abstract: A matching apparatus includes: a data processing unit that identifies information of a user from input data for matching that is input by the user; and a matching processing unit that identifies sound data that matches the user by comparing the identified information with classification information that is associated with each sound data in advance.

Abstract: A sound classification apparatus includes: a learning model classification unit that inputs sound data to be classified into a machine learning model generated by machine learning using sound data and teacher data that serve as training data, and outputs a classification result using an output result from the machine learning model; a condition classification unit that classifies the sound data to be classified, based on information registered in advance, and outputs a classification result; and a sound classification unit 12 that classifies the sound data to be classified, based on the classification result of the learning model classification means and the classification result of the condition classification means.

Abstract: A hearing assistance apparatus including: a speech recognition information generating unit that executes speech recognition processing on first speech information to infer one or more words from the first speech information, and generates speech recognition information by, for each of the one or more inferred words, associating word information representing the inferred word with second speech information corresponding to the inferred word; and a speech output information generating unit that generates, using the second speech information corresponding to the one or more inferred words, speech output information for outputting, to a speech output device, second speech corresponding to the one or more inferred words.

Abstract: The present invention assists a report receiver in swiftly and exactly handling an event. A specification unit specifies, in an input sound signal, a non-voice time in which a reporter who reports the occurrence of the event does not speak, an identification unit identifies a sound source at the occurrence site of the event by analyzing the sound signal in the non-voice time, and a prediction unit predicts a sound scene at the occurrence site of the event on the basis of the identified sound source.

Abstract: The present invention assists an operator in accurately understanding the situation at a scene, even while talking to a caller. A conversion unit converts inputted speech data into text data, an extraction unit extracts words contained in the text data from the text data, a classification unit classifies the text data into one of multiple types on the basis of the words extracted from the text data, and a display unit stores and displays information contained in the text data in a form for each type according to the type of the text data.
