Patent
Voice synthesizing method
TL;DR: In this article, the phase initialization value information is given to the odd and even numbers of the harmonics in order to prevent the adverse effect due to the phase distortion by initializing the phases of harmonics.
Patent
Sound detecting apparatus, sound detecting method, sound feature value detecting apparatus, sound feature value detecting method, sound section detecting apparatus, sound section detecting method, and program
TL;DR: In this paper, the authors provided a sound detecting apparatus including: a feature value extracting unit which extracts feature value per every predetermined time from an input time signal; a feature frequency transform unit and a likelihood distribution detecting unit, which smooths the obtained likelihood distribution in frequency and time directions, and extracts a value per the predetermined time.
Patent
Signal processing apparatus and method, recording medium, and program
TL;DR: In this article, the spectral decomposition of sub-band signals is detected and the detected amplitudes are smoothed and sampled during smoothing, and the amount of spectral change is determined based on the smoothed subband amplitude.
Patent
Device and method for processing signal
TL;DR: In this article, the audio signals or video signals of a broadcasting program are made into frames (short time frame, medium time frame and long time frame) in respectively hierarchically different time zones and the audio signal or video signal in the frames are respectively processed.
Patent
Speech decoding method and apparatus to control the reproduction speed by changing the number of transform coefficients
TL;DR: In this article, a signal decoding method and an apparatus with a data number convertor for converting the number of orthogonal transform coefficients entering a transmission signal input terminal from N to M is described.
