Audio analysis apparatus

摘要

An audio analysis apparatus includes the following components. A strap has an end portion connected to a main body and is used to hang the main body from a user's neck. 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.

主权项

1. An audio analysis apparatus comprising:
a main body; a strap that has an end portion to be connected to the main body and is to be used in order to hang the main body from the neck of a user; a first audio acquisition device that is at the end portion of the strap or in the main body; a second audio acquisition device that is at a position which is separate from the end portion by a first predetermined distance and which is on one side of the strap that extends from the neck of the user; a third audio acquisition device that is at another position which is separate from the end portion by a second predetermined distance and which is on the other side of the strap that extends from the neck of the user, the second predetermined distance being substantially equal to the first predetermined distance; an analysis unit that is in the main body, and that performs an analysis process to discriminate whether a sound acquired by the first audio acquisition device and the second or third audio acquisition device is an uttered voice of the user who is wearing the strap around the neck or an uttered voice of another person on the basis of a result of comparing a first audio signal of the sound acquired by the first audio acquisition device with a second audio signal of the sound acquired by the second audio acquisition device or a third audio signal of the sound acquired by the third audio acquisition device, and to detect an orientation of the face of the user who is wearing the strap around the neck on the basis of a result of comparing the second audio signal with the third audio signal; and a transmission unit that is in the main body and that transmits an analysis result obtained by the analysis unit to an external apparatus.
