Abstract: A voice recognition method is provided that includes extracting a first speech from the sound collected with a microphone connected to a voice processing device, and calculating a recognition result for the first speech and the confidence level of the first speech. The method also includes performing a speech for a repetition request based on the calculated confidence level of the first speech, and extracting with the microphone a second speech obtained through the repetition request. The method further includes calculating a recognition result for the second speech and the confidence level of the second speech, and generating a recognition result from the recognition result for the first speech and the recognition result for the second speech, based on the confidence level of the calculated second speech.

Abstract: When speech of a first user includes a first word that is stored in a memory and associated with the first user, it is determined whether or not a difference between a first time and a second time is equal to or less than a predetermined time. The first time is a current time at which the first user spoke the first word. The second time is a time at which a second user last spoke a second word associated with the first word. When the difference between the first time and the second time is equal to or less than the predetermined time, a speaker outputs speech of a same content associated with the first word and the second word.

Abstract: A topic providing device includes a candidate topic extractor, a provided topic determiner, a voice synthesizer, and a speaker. When a determination is made that a parent and child are conversing and that there is a need to provide a new topic to the parent and child, based on a conversation history database and a child activity database storing at least one activity name indicating an activity the child was engaged in for a first predetermined period of time, the candidate topic extractor extracts at least one candidate topic that corresponds to the at least one activity name in the child activity database and does not correspond to an activity name included in text data recorded in a first database. From the at least one candidate topic, the provided topic determiner selects one topic to provide to the parent and the child. The voice synthesizer generates voice data containing the one topic. The speaker outputs the voice data.

Abstract: A method is provided for correcting a dictionary used in a voice processing apparatus. The method includes first extracting a speech of a target speaker from audio collected by a microphone, and estimating a speech phonemic sequence configuring the speech. The method also includes calculating a match degree, using a first dictionary, between the speech phonemic sequence and a first phonemic sequence that corresponds to a first word registered in the first dictionary, and second extracting the first word corresponding to a highest match degree as a spoken word spoken by the target speaker. The method further includes first correcting a second dictionary based on the highest match degree, the second dictionary indicating a relation between a second word and a third word, and second correcting the second dictionary by correcting the relation between the third word matching the spoken word and the second word.
