Document Type and Number:
WIPO Patent Application WO/2022/145015
Kind Code:
A1
Abstract:
A signal processing device (10) has: a speaker feature vector extraction unit (11) for repeatedly extracting, for an inputted acoustic signal, a speaker feature vector for each time block a number of times commensurate with the number of speakers present in the time block; a memory control instruction unit (13) for instructing to write the speaker feature vector to an unused memory block of an external memory unit (12) when a speaker feature vector of a speaker who has not appeared in a time block thus far is extracted, and instructing to write the speaker feature vector to a memory slot of the external memory unit (12) that corresponds to a speaker who has already appeared when a speaker feature value vector of a speaker who has already appeared in a time block thus far is extracted; and a sound source extraction unit (16), an utterance section detecting unit (17), and a speech recognition unit (18) for executing signal processing on the basis of a speaker feature vector.
