1. A motion analyzer comprising:
- a motion detection unit that detects motion of a part of a body of a subject;
a first voice acquisition unit that is provided in a place where a distance of a sound wave propagation path from a mouth of the subject is a first distance; and
a second voice acquisition unit that is provided in a place where a distance of a sound wave propagation path from the mouth of the subject is smaller than the first distance,a speaking detection unit that detects speaking of the subject on the basis of a sound pressure ratio is a ratio between sound pressure of a voice acquired by the first voice acquisition unit and sound pressure of a voice acquired by the second voice acquisition unit; and
a determination unit that determines 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.

Abstract
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.

4. A voice acquisition apparatus comprising:
-
an apparatus body; a strap that is connected to the apparatus body and is used when the apparatus body is hung from a neck of a subject; a first voice acquisition unit that is provided in the strap or the apparatus body and that is provided in a place where a distance of a sound wave propagation path from a mouth of the subject, which is a distance when the apparatus body is hung from the neck of the subject, is a first distance; a second voice acquisition unit that is provided in the strap and that is provided in a place where a distance of a sound wave propagation path from the mouth of the subject, which is a distance when the apparatus body is hung from the neck of the subject, is smaller than the first distance; and a motion detection unit that is provided in the strap and that detects motion of a part of a body of the subject. - View Dependent Claims (5, 6, 7)

8. A motion analysis system comprising:
-
a terminal apparatus that is worn on a subject; and a host apparatus that acquires information from the terminal apparatus, wherein the terminal apparatus includes; a motion detection unit that detects motion of a part of a body of the subject; a voice acquisition unit that acquires a voice, the voice acquisition unit comprises; a first voice acquisition unit that is provided in a place where a distance of a sound wave propagation path from a mouth of the subject is a first distance; a second voice acquisition unit that is provided in a place where a distance of a sound wave propagation path from the mouth of the subject is smaller than the first distance; and a speaking detection unit that detects speaking of the subject on the basis of a sound pressure ratio which is a ratio between sound pressure of a voice acquired by the on unit and sound pressure of a voice acquired by the second voice acquisition unit; an identification unit that identifies whether a voice acquired by the voice acquisition unit is a voice of the subject or voices of others; and a signal transmission unit that transmits speaking information that is information regarding a voice signal, which includes an identification result of the identification unit, and a detection result of the motion detection unit to the host apparatus, and the host apparatus includes; a signal receiving unit that receives the speaking information and the detection result transmitted from the terminal apparatus; and a determination unit that determines whether or not the subject has performed predetermined motion on the basis of the speaking information and the detection result received by the signal receiving unit. - View Dependent Claims (9)

10. A motion analysis method comprising:
-
detecting motion of a part of a body of a subject; providing a first voice acquisition unit that is provided in a place where a distance of a sound wave propagation path from a mouth of the subject is a first distance; providing a second voice acquisition unit that is provided in a place where a distance of a sound wave propagation path from the mouth of the subject is smaller than the first distance, detecting speaking of the subject on the basis of a sound pressure ratio which is a ratio between sound pressure of a voice acquired by the first voice acquisition unit and sound pressure of a voice acquired by the second voice acquisition unit; determining that the subject has performed predetermined motion when motion of a part of the body is detected in the detecting step of the motion and speaking of the subject is detected in the detecting step of the speaking.
