Název v původním jazyce

Modeling roughness perception for complex stimuli using a model of cochlear hydrodynamics.

Popis výsledku v původním jazyce

A roughness model composed of a physiological auditory model and an algorithm calculating roughness from the envelope of the auditory model output signal is described in the study. The roughness model is sensitive to phase changes between the spectral components and to shape of the temporal waveform of the analyzed stimuli which limits most of the state of the art roughness models. Synthetic and real complex stimuli were used in this study to test the model performance. Amplitude modulated harmonic complexes and intervals in the chromatic scale composed of harmonic complexes were among the synthetic stimuli. Voice samples of a vowel /a/ extracted from the signal recorded during the scale signing were used as the real stimuli. Some of the samples were dysphonic (with roughness). Listening tests were conducted to obtain roughness ratings of the stimuli. The subjective roughness ratings correlated with the ratings predicted by the presented roughness model.
