摘要： An acoustic signal processing apparatus (100) disclosed in the present application includes a detecting unit (120), a calculating unit (130), an accumulating unit (150), and a determining unit (160). The detecting unit (120) detects an acoustic signal that is contained in a sound input signal and that is generated by a human body. The calculating unit (130) calculates an effective volume indicating an effective volume of the acoustic signal detected by the detecting unit (120), based on the input signal. The accumulating unit (150) accumulates the effective volumes calculated by the calculating units (130) to calculate the accumulated effective volume. The determining unit (160) determines whether the accumulated effective volume calculated by the accumulating unit (150) has reached a predetermined threshold.

摘要： A method and system for allowing access to computer functions such as websites that utilizes a user's ability to recognize sounds is described. The method presents a user a series of sounds. Some of the sounds presented in the series are labeled as validation sounds. The user is asked to provide an input every time he or she hears the validation sound. The user must identify the sound within a specified length of time. The system disclosed comprises a user interface, a sound database module, a generation module, and a sound database module. The generation module creates the validation test file and expected answer. The answer confirmation module checks the input from the requesting computer and provides access to the computer function if the computer input from the requesting computer meets the required parameters.

摘要： To classify moving images using audio signals. An audio signal is acquired, a section feature relating to an audio frequency distribution is extracted with respect to each of a plurality of sections each having a predetermined length contained in the acquired audio signal, each extracted section feature is compared with each of reference section features to calculate a section similarity indicating a degree of correlation between each section feature and each reference section feature. An integrated feature relating to the plurality of sections and being calculated based on the section similarity calculated with respect to each of the plurality of sections is extracted from the acquired audio signal. The extracted integrated feature is compared with each of one or more reference integrated features, and the audio signal is classified based on comparison result. Then, classification result is used for moving image classification.

摘要： An audio communication device (10) comprises an input (12) connectable to a narrowband audio signal source (14). The input 12 can receive a narrowband audio signal (16) having a first bandwidth. An extraction unit (18) is connected to the input and arranged to extract a plurality of narrowband parameters (20, 22) from the narrowband audio signal. An extrapolation unit (24) is connected to receive the plurality of narrowband parameters and arranged to generate a plurality of wideband parameters (26) from the plurality of narrowband parameters. The extrapolation unit comprises one or more adaptive neuro-fuzzy inference system (ANFIS) modules (28). The device (10) further comprises a synthesis unit (30) connected to receive the plurality of wideband parameters and arranged to generate, using the wideband parameters, a synthesized wideband audio signal (32) having a second bandwidth wider than the first bandwidth. And the device comprises an output (43) connectable to an acoustic transducer (47) arranged to output for humans perceptible acoustic signals, for providing said synthesized wideband audio signal to the acoustic transducer.

摘要： The invention relates to a method of identifying and correcting errors in a noisy binary mask. An object of the present invention is to provide a scheme for improving a binary mask representing speech. The problem is solved in that the method comprises a) providing a noisy binary mask comprising a binary representation of the power density of an acoustic signal comprising a target signal and a noise signal at a predefined number of discrete frequencies and a number of discrete time instances; b) providing a statistical model of a clean binary mask representing the target signal; and c) using the statistical model to detect and correct errors in the noisy binary mask. This has the advantage of providing an alternative and relatively simple way of improving an estimate of a binary mask representing a speech signal. The invention may e.g. be used for the speech processing, e.g. in a hearing instrument.

摘要： A method (100) includes receiving (101) an input digital audio signal comprising a narrow-band signal. The input digital audio signal is processed (102) to generate a processed digital audio signal. A high-band energy level corresponding to the input digital audio signal is estimated (103) based on an estimated enery of a transition- band of the processed digital audio signal within a predetermined upper frequency range of a narrow-band bandwidth. A high-band digital audio signal is generated (104) based on the high-band energy level and an estimated high-band spectrum corresponding to the high-band energy level.
