A sound analysis apparatus includes a sound information obtaining section chat obtains information relating to a sound acquired by a sound acquiring section that acquires the sound and distinguishes a spoken voice of a wearer from a spoken voice of another person, a phase difference deriving section that derives a relationship between a frequency and a phase difference with respect to the sound acquired by the plural sound acquiring sections, a dispersion deriving section that derives a dispersion that is the level of irregularity of the derived phase difference, and a distance deriving section that derives a distance between the wearer and the other person using a first dispersion derived in a case where the sound is distinguished as the spoken voice of the other person and a second dispersion derived in a case where the sound is distinguished as the spoken voice of the wearer.

Sound analysis apparatus for detecting sound sources

A voice analyzer includes an apparatus body, a strap that is connected to the apparatus body and is used to hang the apparatus body from a neck of a user, a first voice acquisition unit provided in the strap or the apparatus body, a second voice acquisition unit provided at a position where a distance of a sound wave propagation path from a mouth of the user is smaller than a distance of a sound wave propagation path from the mouth of the user to the first voice acquisition unit, and an identification unit that identifies a sound, in which first sound pressure acquired by the first voice acquisition unit is larger by a predetermined value or more than second sound pressure acquired by the second voice acquisition unit, on the basis of a result of comparison between the first sound pressure and the second sound pressure.

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.

A motion analyzer may include a motion detection unit, a speaking detection unit, and a determination unit. The motion detection unit may detect motion of a part of a body of a subject. The speaking detection unit may detect speaking of the subject. The determination unit may determine that the subject has performed predetermined motion when motion of a part of the body is detected by the motion detection unit and speaking of the subject is detected by the speaking detection unit.

An audio analysis system includes a terminal apparatus and a host system. The terminal apparatus acquires an audio signal of a sound containing utterances of a user and another person, discriminates between portions of the audio signal corresponding to the utterances of the user and the other person, detects an utterance feature based on the portion corresponding to the utterance of the user or the other person, and transmits utterance information including the discrimination and detection results to the host system. The host system detects a part corresponding to a conversation from the received utterance information, detects portions of the part of the utterance information corresponding to the user and the other person, compares a combination of plural utterance features corresponding to the portions of the part of the utterance information of the user and the other person with relation information to estimate an emotion, and outputs estimation information.

A first audio acquisition device is at the end portion or in the main body. Second and third audio acquisition devices are at positions separate from the end portion by substantially the same predetermined distances, on the respective sides of the strap extending from the user's neck. An analysis unit discriminates whether an acquired sound is an uttered voice of the user or another person by comparing audio signals of acquired by the first and second or third audio acquisition devices and detects an orientation of the user's face by comparing the audio signals acquired by the second and third audio acquisition devices. A transmission unit transmits the analysis result to an external apparatus.
