Speech perception is still a much complex process far from being fully understood. To gain some insight on specific open problems in its automatic treatment (recognition, synthesis, diarization, segmentation, etc.) neuromorphisms and knowledge derived from the understanding on how the Auditory System proceeds may be of crucial importance. The present paper is part of a series of preliminary work carried out trying to translate some of this understanding to solve specific tasks as speech segmentation and labeling in a parallel way to the neural resources found in the Auditory Pathways and Cortex. The bio-inspired (neuromorphic) design of some elementary units (responsible for receptive field implementation) covering simple tasks as static and dynamic formant tracking, or vowel labeling is exposed. In a further step it is shown how simply neural circuits employing these units may convey successful vowel-consonant separation independently of the speaker. The paper is illustrated with results from simulations.
