Abstract: A purchase settlement method is provided. Voice information is acquired. A spoken command indicating a control instruction as to a device is obtained based on the acquired voice information. When the spoken command relates to purchase settlement, speaker information relating to a speaker who has spoken the acquired voice information is identified based on the acquired voice information. It is determined whether or not the identified speaker information is of a speaker permitted to perform purchase settlement by referencing a table in which speaker information of speakers permitted to perform purchase settlement and information necessary for purchase settlement are associated with each other. When it is determined that the identified speaker information is of the speaker permitted to perform purchase settlement, purchase settlement processing is performed using the spoken command and the information necessary for purchase settlement.

Abstract: An acoustic processing method includes: obtaining (i) sound information related to a sound including a predetermined sound and (ii) metadata including information related to a space in which the predetermined sound is reproduced; performing, based on the sound information and the metadata, acoustic processing of generating a sound signal expressing a sound including an early reflection that reaches a user after a direct sound that reaches the user directly from a sound source object; and outputting an output sound signal including the sound signal. The acoustic processing includes: determining parameters for generating the early reflection, the parameters including a position, in the space, of a virtual sound source object that generates the early reflection; and generating the early reflection based on the parameters determined. The parameters include at least a parameter that varies over time according to a predetermined condition.
