Method of correcting dictionary, program for correcting dictionary, voice processing apparatus, and robot

A non-transitory computer readable storage medium encoded with an executable computer program for correcting a dictionary used in a voice processing apparatus, that when executed by a processor causes the processor to perform operations, the operations comprising:

• first extracting a speech of a target speaker from audio collected from a microphone corresponding to the voice processing apparatus;
• estimating a speech phonemic sequence configuring the speech;
• 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, the first dictionary being stored in a memory included in the voice processing apparatus and indicating a corresponding relation between the first word and the first phonemic sequence;
• second extracting, from the first dictionary, the first word corresponding to a highest match degree as a spoken word spoken by the target speaker;
• first correcting a second dictionary based on the highest match degree, the second dictionary indicating a corresponding relation between a second word and a third word, the third word corresponding to a language unit spoken by the target speaker intending to speak the second word;
• and
• second correcting the second dictionary by correcting the corresponding relation between the third word matching the spoken word and second word that corresponds to the third word.
