Abstract:According to the situation that speech authentication algorithms are not appropriated for real-time speech content authentication, a novel speech perceptual hashing authentication algorithm based on discrete wavelet transform with combination of time-frequency domain features was proposed. Firstly, by discrete wavelet transform (DWT), a new signal in frequency domain is generated from the original speech signal after pre-processing and intensity-loudness transform (ILT). Next, the algorithm partitions low freq… Show more
