RT Conference Proceedings T1 Morphological processing of a dynamic compressive gammachirp filterbank for automatic speech recognition A1 Cadore, Joyner A1 Peláez Moreno, Carmen A1 Gallardo Antolín, Ascensión AB The Dynamic Compressive Gammachirp is presented for producing auditory-inspired feature extraction in Automatic Speech Recognition. The proposed acoustic features combine spectral subtraction and two-dimensional non-linear filtering technique most usually employed for image processing: morphological filtering. These features have been proven to be more robust to noisy speech than those based on simpler auditory filterbanks like the classical mel-scaled triangular filterbank, the Gammatone filterbank and the passive Gammachirp in a noisy Isolet database.
