摘要： The sound acquisition apparatus broadcasts a sound “output notice request” through a communication network. In response to the request by the sound acquisition apparatus, the sound output apparatus gives notification of starting a sound output operation, the sound acquisition apparatus requests the sound output apparatus to transfer “output sound data”. The sound output apparatus then transfers “output sound data” representing the sound outputted by its own speaker to the sound acquisition apparatus in response to this request. The sound acquisition apparatus then suppresses a noise component from sound data acquired through a microphone using the transferred “output sound data”.

摘要： A portable terminal device can extrapolate the position of a sound source in the thicknesswise direction regardless of the use style. A slide type portable terminal has an upper casing, a lower casing, and a coupling part that couples the casings in such a way that their positional relation is changeable. The upper casing has a plurality of first microphones, and the lower casing has a second microphone. In a handhold style, one of the first microphones and the second microphone are lined in the thicknesswise direction of the cellular phone. As the upper casing is slid, the other one of the first microphones and the second microphone are lined in the thicknesswise direction of the cellular phone. The position of a sound source in the thicknesswise direction can be extrapolated from output signals of a formed microphone array in the thicknesswise direction.

摘要： Conventional independent component analysis has had a problem that performance deteriorates when the number of sound sources exceeds the number of microphones. Conventional l1 norm minimization method assumes that noises other than sound sources do not exist, and is problematic in that performance deteriorates in environments in which noises other than voices such as echoes and reverberations exist. The present invention considers the power of a noise component as a cost function in addition to an l1 norm used as a cost function when the l1 norm minimization method separates sounds. In the l1 norm minimization method, a cost function is defined on the assumption that voice has no relation to a time direction. However, in the present invention, a cost function is defined on the assumption that voice has a relation to a time direction, and because of its construction, a solution having a relation to a time direction is easily selected.
摘要翻译：传统的独立分量分析存在的问题是，当声源的数量超过麦克风的数量时，性能会恶化。常规的l1范数最小化方法假设不存在除声源之外的噪声，并且在存在诸如回声和混响的声音之外的环境的环境中性能恶化是有问题的。除了作为成本函数的l1范数之外，本发明考虑噪声分量的功率作为成本函数，当l1范数最小化方法分离声音时。在l1范数最小化方法中，假定语音与时间方向无关，则定义成本函数。然而，在本发明中，在语音与时间方向有关系的假设下定义成本函数，并且由于其构造，容易选择与时间方向有关的解决方案。

摘要： Monitoring accuracy degrades due to a noise in an environment where there are many sound sources other than those to be monitored. Easy initialization is required for an environment where many apparatuses operate. A sound monitoring system includes a microphone array having multiple microphones and a location-based abnormal sound monitoring section as a processing section. The location-based abnormal sound monitoring section is supplied with an input signal from the microphone array via a waveform acquisition section and a network. Using the input signal, the location-based abnormal sound monitoring section detects a temporal change in a sound source direction histogram. Based on a detected change result, the location-based abnormal sound monitoring section checks for abnormality in a sound field and outputs a monitoring result. The processing section searches for a microphone array near the sound source to be monitored. The processing section selects a sound field monitoring function for the sound source to be monitored based on various data concerning a microphone belonging to the searched microphone array.
