  • Patent number: 9704504
    Abstract: The voice analysis device includes: a voice information acquiring unit that acquires a voice signal generated by plural voice acquiring units disposed at different distances from a speaking section of a speaker and acquiring voice of the speaker; and an identification unit that identifies the speaker corresponding to the voice having been acquired, on the basis of intensities of respective peaks in a frequency spectrum of a first enhanced waveform and a frequency spectrum of a second enhanced waveform. The first enhanced waveform is a waveform where a voice signal of a predetermined target speaker has been enhanced, and the second enhanced waveform is a waveform where a voice signal of a speaker other than the target speaker has been enhanced.

  • Patent number: 9014395
    Abstract: 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.

  • Patent number: 8892424
    Abstract: 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.

  • Patent number: 8855331
    Abstract: 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.
