Abstract
An information processing method includes obtaining an audio signal that represents sound collected by a sound collecting device; calculating, using the audio signal obtained, a volume of the sound collected by the sound collecting device; identifying, using the audio signal obtained, a type of a sound source of the sound collected by the sound collecting device; estimating a distance between the sound collecting device and the sound source of the sound collected by the sound collecting device based on a standard volume and the volume calculated, the standard volume being (i) stored in a database in which the type of the sound source and the standard volume are preassociated with each other, (ii) the volume of the sound from the sound source at a predetermined distance, and (iii) associated with the type of the sound source identified; and outputting an estimation result.
