Abstract

A voice analyzer includes a plate-shaped body, a plurality of first voice acquisition units that are placed on both surfaces of the plate-shaped body and that acquire a voice of a speaker, a sound pressure comparison unit that compares sound pressure of a voice acquired by the first voice acquisition unit placed on one surface of the plate-shaped body with sound pressure of a voice acquired by the first voice acquisition unit placed on the other surface and determines a larger sound pressure, and a voice signal selection unit that selects information regarding a voice signal which is associated with the larger sound pressure and is determined by the sound pressure comparison unit.

First claim

What is claimed is:

1. A voice analyzer comprising:
a plate-shaped body;
a plurality of first voice acquisition units that are placed on both surfaces of the plate-shaped body and that acquire a voice of a speaker;
a sound pressure comparison unit that compares sound pressure of a voice acquired by a first voice acquisition unit placed on one surface of the plate-shaped body with sound pressure of a voice acquired by a first voice acquisition unit placed on the other surface of the plate-shaped body and determines a larger sound pressure;
a voice signal selection unit that selects information regarding a voice signal that is associated with the larger sound pressure and is determined by the sound pressure comparison unit;
a string member that is strap shaped, the string member connected to the plate-shaped body and used so that the plate-shaped body may be hung from a neck of a wearer of the voice analyzer; and
a positional relationship determination unit that determines that the first voice acquisition unit for the voice signal selected by the voice signal selection unit faces an outside of the wearer.

2. The voice analyzer according to claim 1 , further comprising:
a plurality of second voice acquisition units that are provided in the string member,
wherein the second voice acquisition units are associated with positional relationship in a horizontal direction between the second voice acquisition units provided in the string member and positional relationship between the first voice acquisition units placed on both the surfaces of the plate-shaped body.

3. The voice analyzer according to claim 1 ,
wherein the string member is connected to the plate-shaped body in a state where both ends of the string member are separated from each other by a predetermined distance in a horizontal direction of the plate-shaped body.

4. The voice analyzer according to claim 2 , further comprising:
a speaker identification unit that identifies whether the speaker is the wearer or others on the basis of a sound pressure difference between voices acquired by two voice acquisition units whose distances from a mouth of the wearer are different among the voice acquisition units.

5. The voice analyzer according to claim 3 , further comprising:
a speaker identification unit that identifies whether the speaker is the wearer or others on the basis of a sound pressure difference between voices acquired by two voice acquisition units whose distances from a mouth of the wearer are different among the voice acquisition units.

6. A voice analysis system comprising:
a voice analysis unit that includes:
a plate-shaped unit body;
a string member that is strap shaped, the string member connected to the plate-shaped body and used so that the plate-shaped body may be hung from a neck of a wearer of the voice analyzer;
a plurality of voice acquisition sections that are placed on both surfaces of the plate-shaped unit body and that acquire a voice of a speaker;
a sound pressure comparison section that compares sound pressure of a voice acquired by a voice acquisition section placed on one surface of the unit body with sound pressure of a voice acquired by a voice acquisition section placed on the other surface of the unit body and determines a larger sound pressure;
a voice signal selection section that selects information regarding a voice signal that is associated with the larger sound pressure and is determined by the sound comparison unit;
a signal receiving unit that receives the information regarding the voice signal; and
a positional relationship determination unit that determines that the voice acquisition section for the voice signal selected by the voice signal selection unit faces an outside of the wearer.

7. A non-transitory computer readable medium storing a program causing a computer to perform a process,
the process comprising:
acquiring a voice of a speaker from a plurality of voice acquisition units that are placed on both surfaces of a plate-shaped body connected to a string member so that the plate-shaped body may be hung from the neck of a wearer;
comparing sound pressure of a voice acquired by a voice acquisition unit placed on one surface of the plate-shaped body with sound pressure of a voice acquired by a voice acquisition unit placed on the other surface of the plate-shaped body and determining a larger sound pressure;
selecting information regarding a voice signal that is associated with the larger sound pressure and is determined by the sound pressure comparison; and
determining that the voice acquisition unit for the selected voice signal faces an outside of the wearer.

8. The voice analyzer according to claim 4 ,
wherein the speaker identification unit identifies whether the speaker is the wearer or others based on the first voice acquisition unit that is determined to face the outside and not based on the first voice acquisition unit that is not determined to face the outside.
