20120020466 | System And Method For Identifying Audio Command Prompts For Use In A Voice Response Environment - A system and method for identifying audio command prompts for use in a voice response environment is provided. A signature is generated for audio samples each having preceding audio, reference phrase audio, and trailing audio segments. The trailing segment is removed and each of the preceding and reference phrase segments are divided into buffers. The buffers are transformed into discrete fourier transform buffers. One of the discrete fourier transform buffers from the reference phrase segment that is dissimilar to each of the discrete fourier transform buffers from the preceding segment is selected as the signature. Audio command prompts are processed to generate a discrete fourier transform. Each discrete fourier transform for the audio command prompts is compared with each of the signatures and a correlation value is determined. One such audio command prompt matches one such signature when the correlation value for that audio command prompt satisfies a threshold. | 01-26-2012 |
20130346083 | Computer-Implemented System And Method For User-Controlled Processing Of Audio Signals - A computer-implemented system and method for user-controlled processing of audio signals is provided. An audio signal including a reference segment and a segment preceding the reference segment is obtained. A value q is received from a user. Audio buffers in the preceding segment are defined, each having a width of N samples and a starting point a unique number of samples away from the preceding segment's start, based on a division of N by q. One or more of the buffers are transformed into discrete Fourier transform (DFT) buffers. A signature of the signal is generated using at least a portion of the reference segment and at least one of the DFT buffers. A new audio signal is received and a DFT for the audio signal is generated. The new audio signal is determined to match the audio signal based on a comparison of the DFT to the signature. | 12-26-2013 |
20140082079 | SYSTEM AND METHOD FOR THE COLLABORATIVE RECORDING, UPLOADING AND SHARING OF MULTIMEDIA CONTENT OVER A COMPUTER NETWORK - A method and system for providing multimedia content to a user is described. The multimedia content may include a plurality of multimedia items. The method includes receiving the multimedia items, and determining whether the overlap(s) exist between the multimedia items. This determination is made using discrete Fourier transform(s) (DFTs) of audio data for each multimedia item. The method also includes storing the multimedia items in a file store. | 03-20-2014 |
