A function is applied to the audio detection and speech recognition signals to generate a non-speech audio detection signal identifying presence of non-speech audio in the input audio stream when the audio detection signal is asserted and the speech recognition signal is not asserted. A control or indication action is performed in the computer system based on assertion of the non-speech audio detection signal.
Scaling for gain shape circuitry
A method of operation of a device includes receiving a first set of samples and a second set of samples. The first set of samples corresponds to a portion of a first audio frame and the second set of samples corresponds to a second audio frame. The method further includes generating a target set of samples based on the first set of samples and a first subset of the second set of samples and generating a reference set of samples based at least partially on a second subset of the second set of samples. The method also includes scaling the target set of samples to generate a scaled target set of samples and generating a third set of samples based on the scaled target set of samples and one or more samples of the second set of samples.

An apparatus for decoding an encoded audio signal is provided. The apparatus includes a pulse information decoder and a signal decoder. The pulse information decoder is adapted to decode a plurality of pulse positions, wherein each one of the pulse positions indicates a position of one of the pulses of the track, wherein the pulse information decoder is configured to decode the plurality of pulse positions by using a track positions number, a total pulses number, and one state number. The signal decoder is adapted to decode the encoded audio signal by generating a synthesized audio signal using the plurality of pulse positions and a plurality of predictive filter coefficients.
Linear prediction based coding scheme using spectral domain noise shaping
An encoding concept which is linear prediction based and uses spectral domain noise shaping is rendered less complex at a comparable coding efficiency in terms of, for example, rate/distortion ratio, by using the spectral decomposition of the audio input signal into a spectrogram having a sequence of spectra for both linear prediction coefficient computation as well as spectral domain shaping based on the linear prediction coefficients. The coding efficiency may remain even if such a lapped transform is used for the spectral decomposition which causes aliasing and necessitates time aliasing cancellation such as critically sampled lapped transforms such as an MDCT.

Downsampling schemes in a hierarchical neural network structure for phoneme recognition
An approach for phoneme recognition is described. A sequence of intermediate output posterior vectors is generated from an input sequence of cepstral features using a first layer perceptron. The intermediate output posterior vectors are then downsampled to form a reduced input set of intermediate posterior vectors for a second layer perceptron. A sequence of final posterior vectors is generated from the reduced input set of intermediate posterior vectors using the second layer perceptron. Then the final posterior vectors are decoded to determine an output recognized phoneme sequence representative of the input sequence of cepstral features.

Addressable drawer organizer with item display panel
A drawer organizer for facilitating the location of an item stored in one of several drawers in one or more drawer organizer cabinets. Each drawer has an LED and a display device mounted on a front panel, as well as a CPU and a display device driver. The CPU memory contains the address of the associated drawer and communicates with an associated controller which receives drawer address and display information from a host computer. A user specifies an item to be retrieved from one of the cabinet drawers, the host computer transmits drawer identification signals to the controller, which converts these signals to a drawer address and supplies the drawer address to all drawer CPUs in the cabinet. If the incoming address matches the address stored in CPU memory of one of the drawers, this result is conveyed via the controller to the host computer, which then sends item display information to the controller. The controller forwards this information to the CPU, which relays this information to the display device driver and the information is displayed to the user. The CPU also activates the drawer LED.
