摘要
To provide a speaker determination device which is improved in speaker determination precision.SOLUTION: A speaker determination device includes: a similarity calculation part which calculates similarity between a speaker feature quantity of each divided speech section obtained by dividing a speech section of a speech signal according to a predetermined time length and a speaker feature quantity previously generated for each person in charge of window work; a speaker primary determination part which generates primary determination information representing a speaker ID of each divided speech section from the similarity; a speaker secondary determination part which generates secondary determination information by using a speaker ID of a nearby speaker as secondary determination information of an arbitrary divided speech section when similarity between a speaker feature quantity of the nearby speaker as the most matching speaker in a predetermined number of divided speech sections before or after the arbitrary divided speech section and a speaker feature quantity of the arbitrary divided speed section meets predetermined conditions; and a speaker clustering part which generates a speaker ID of a customer by clustering speaker feature quantities of divided speech sections corresponding to the secondary determination information representing the customer, i.e., a set of customer speaker feature quantities so as to generate tertiary determination information.SELECTED DRAWING: Figure 1
