<p>A voice prosthesis consists of a cheap, light portable hygeometric apparatus having a fast electro conductive response time. The apparatus provides temporal discous of gaseous flow and linear measurement of multi litre volumes of gas flux. A dielectric gas conduit shaped in the form of a crown or segment thereof forms a frame. The frame is circular and includes a dry satire system covering a prescribed longitudinal and perimetric length of the gas conduit. The satine system is deposited at the extremity of the support conduit, and is connected to electrodes for connection to a recording circuit.</p> |
