摘要： A voice activity detection method in a low SNR environment. The voice activity detection is performed by extracting a long-term spectrum variation component and a harmonic structure as feature vectors from a speech signal and increasing difference in feature vectors between speech and non-speech (i) using the long-term spectrum variation component feature or (ii) using a long-term spectrum variation component extraction and a harmonic structure feature extraction. A correct rate and an accuracy rate of the voice activity detection is improved over conventional methods by using a long-term spectrum variation component having a window length over an average phoneme duration of an utterance in the speech signal. The voice activity detection system and method provides speech processing, automatic speech recognition, and speech output capable of very accurate voice activity detection.

摘要： The present invention relates to a system, method and program for speech recognition. In an embodiment of the invention a method for processing a speech signal consists of receiving a power spectrum of a speech signal and generating a log power spectrum signal of the power spectrum. The method further consists of performing discrete cosine transformation on the log power spectrum signal and cutting off cepstrum upper and lower terms of the discrete cosine transformed signal. The method further consists of performing inverse discrete cosine transformation on the signal from which the cepstrum upper and lower terms are cut off. The method further consists of converting the inverse discrete cosine transformed signal so as to bring the signal back to a power spectrum domain and filtering the power spectrum of the speech signal by using, as a filter, the signal which is brought back to the power spectrum domain.

摘要： Method for processing speech signal data. A speech signal is divided into frames. Each frame is characterized by a frame number T representing a unique interval of time. Each speech signal is characterized by a power spectrum with respect to frame T and frequency band ω. A speech segment and a reverberation segment of the speech signal is determined. L filter coefficients W(k) (k=1, 2, . . . , L) respectively corresponding to L frames immediately preceding frame T are computed such that the L filter coefficients minimize a function Φ that is a linear combination of sum of squares of a residual speech power in the reverberation segment and a sum of squares of a subtracted speech power in the speech segment. The computed L filter coefficients are stored within storage media of the computing apparatus.

摘要： A chemical liquid injection system with which a chemical liquid in a chemical liquid container can be directly injected into a patient without using an intervening liquid syringe or the like.A trailing end of chemical liquid injection tube 120 that its leading end is connected to the patient is placed at a lower position within chemical liquid container 200. A leading end of liquid supply tube 110 is placed at a upper position within chemical liquid container 200 and a trailing end of liquid supply tube 110 is connected to liquid container 300. Since liquid pressure-feeding mechanism 131 feeds the liquid in liquid container 300 into chemical liquid container 200 from liquid supply tube 110 with pressure, the chemical liquid is directly injected into the patient from chemical liquid container 200 through chemical liquid tube 120.

摘要： An input operation device, wherein a manual operation element (401) is shielded by an element shielding member (411) normally openably supported by a member pivoting mechanism (412) and energized to a shielding position by a shielding energizing mechanism (416). In this state, when the element shielding member (411) is displaced to an open position, the manual operation element (401) is opened to get ready for operation. The element shielding member (411) displaced to the open position is temporarily held by a temporary holding mechanism (424), and opened after a specified time is passed. Accordingly, the manual operation element (401) can be operated with a finger used for displacing the element shielding member (411) from the shielding position to the open position. As a result, the input operation device capable of easily manually operating the manual operation element merely by one hand can be provided despite the fact that the manual operation element is automatically shielded by the element shielding member.
