1. An audio signal processing device comprising:
an operation input reception unit that receives an operation input made by a user;
a noise removal unit that performs noise removal processing for removing noise from a collected audio signal collected by a microphone;
an acquisition unit that acquires user identification information for identifying who the user using the audio signal processing device is; and
a storage unit that stores a parameter that determines content of the noise removal processing, such that the parameter is stored in association with the user identification information having been acquired by the acquisition unit, wherein:
the noise removal unit performs the noise removal processing by changing the content of the noise removal processing according to content of the operation input and using the parameter stored in association with the user identification information having been acquired by the acquisition unit, and subsequently adjusts, on a basis of a result of the noise removal processing, a value of the parameter stored in association with the user identification information having been acquired by the acquisition unit,
the noise removal unit changes the content of the noise removal processing according to a first case in which the operation input has been received and a second case in which the operation input has not been received, and
the noise removal unit performs the noise removal processing, by using, as inputs to the noise removal processing, divided collected audio signals associated with unit times and obtained by dividing, for each of the unit times, the collected audio signal collected while the audio signal processing device is being used by a user, makes mutually different kinds of adjustments to determine content of the noise removal processing according to a first case in which the operation input has been received during a unit time constituting the unit times and corresponding to each of one or more of the divided collected audio signals and a second case in which the operation input has not been received during the unit time, and performs, with respect to a target divided collected audio signal included in the divided collected audio signals and associated with each of the unit times, the noise removal processing having the content determined by the mutually different kinds of adjustments, according to whether or not the operation input has been received during a unit time constituting the unit times and corresponding to the target divided collected audio signal.
