The human auditory system has the ability to segregate complex auditory scenes into a foreground component and a background, allowing us to listen to specific speech sounds from a mixture of sounds. Selective attention plays a crucial role in this process, colloquially known as the "cocktail party effect." It has not been possible to build a machine that can emulate this human ability in real-t...

We propose an Auditory VOCODER to resynthesize sound from the Auditory Mellin Image which is an auditory representation that segregates the size and shape information of incoming sound. The sound resynthesis part consists of three techniques: the STRAIGHT VOCODER [2], frequency-warping cepstral analysis [4,12], and nonlinear multivariate regression analysis (MRA). We explain these methods and t...

The acoustic modality is of paramount importance for human inter-individual communication. Consequently, the human auditory system is highly differentiated and able to perform sophisticated tasks such as the identification, recognition and segregation of concurrent sound sources in acoustically adverse conditions – e.g., in reverberant or noisy environments. To this end the different stages of ...

In everyday acoustic scenes, figure-ground segregation typically requires one to group together sound elements over both time and frequency. Electroencephalogram was recorded while listeners detected repeating tonal complexes composed of a random set of pure tones within stimuli consisting of randomly varying tonal elements. The repeating pattern was perceived as a figure over the randomly chan...
