摘要： A sound classification system for adding and correcting a sound type is disclosed. When the add/correct command processor receives a command to add or correct a sound type, the data in the first database is stored in the second database, and the type adding/correcting device adds the feature of the sound to the first database, and re-calculates the statistical values. Besides, the classifier re-classifies the sample sounds, and the precision calculator calculates a ratio of accurate classification. When the ratio is high, the type adding/correcting device stores, in the feature database, the feature of the sound for which a type is to be added or corrected. When the ratio is low, the second database restores the data back to the first database.

摘要： [PROBLEM]
It is an object of the present invention to provide a voice communication apparatus which can prevent its echo suppressing characteristic from being deteriorated in response to the varied relative location of the microphone unit with respect to the speaker unit, and maintain the quality of the near-end signal to be transmitted to the far-end speaker.
[MEANS FOR SOLVING]
Herein disclosed is a voice communication apparatus to be provided with a current value detecting unit 131 for detecting a current parameter value related to the relative location of either the first near-end voice converting unit 121 or the second near-end voice converting unit 122 with respect to the far-end signal converting unit 112, each of the first and second near-end signal delay sections 133 and 134 being operative to delay the near-end signal on the basis of the current parameter value detected by the current value detecting unit 131, and the first outputting section 135 being operative to output a signal indicative of the signal difference between the near-end signals respectively delayed by the first and second near-end signal delay sections 133 and 134.
