Changes in Speech Spectrum due to Changes in Hearing Conditions

The observed change of spectral charcteristics of the voice under blockade (partial or complete) of the voice-hearing feedback, has lead us to investigate it. For the purpose of the research we have set up the experiment and the comparison of speech characteristics with and without protective headphones was done. In this article the methods that enables measurements of speech changes under various hearing conditions were proposed. Measurements of voice change enable analysis of mutual relation: between hearing and voice, as well as the mechanisc of the articulation.
