A LIVE EVALUATION OF THE RASTI-METHOD

The RASTI-method is a simplified version of the speech transmission in dex, that has been evaluated in several languages. In this paper, a co mparative study of the scores of speech intelligibility obtained by th e traditional speaker-listener tests in the Spanish language and the R ASTI-method has been carried out in classrooms. The list of monosyllab ic words used are phonetically balanced and representative of the Span ish language. The percentage of monosyllables giving a poor and bad RA STI-index decreased more slowly when the words were pronounced without a prerecorded voice.
