Abstract
An audio analysis apparatus includes the following components. A main body includes a discrimination unit and a transmission unit. A strap is used for hanging the main body from a user's neck. A first audio acquisition device is provided to the strap or the main body. A second audio acquisition device is provided to the strap at a position where a distance between the second audio acquisition device and the user's mouth is smaller than the distance between the first audio acquisition device and the user's in a state where the strap is worn around the user's neck. The discrimination unit discriminates whether an acquired sound is an uttered voice of the user or of another person by comparing audio signals of the sound acquired by the first and second audio acquisition devices. The transmission unit transmits information including the discrimination result to an external apparatus.
