Madrid, 21-23 noviembre 2012.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.10application/pdfengAtribución-NoComercial-SinDerivadas 3.0 EspañaSpectral subtractionMorphological processingAutomatic speech recognitionAuditory-based features.conference posterTelecomunicacionesopen access5362Proceedings IberSPEECH 2012: VII Jornadas en Tecnología del Habla and III Iberian SLTech WorkshopCC/0000017729
