L'Analisi elettrocustica del linguaggio

Abstract

FOR the purpose of studying spoken language from the linguistic point of view, the authors obtained registrations on strips of sensitised paper by means of a microphone connected to a wire-loop oscillograph (Duddell). One of the problems handled is the nature of the vowels. A curve of ah, for example, is divided by the authors into 75 vibratory bits of similar, but not identical, character occurring in immediate succession. To obtain a numerical expression for the curve in a vibratory bit two methods are used. In one of them the form of the wave the vibration profile is expressed as the sum of a series of sinusoids with frequencies in the relations 1, 2, 3, . . . whereby the number 1 corresponds to the number of times with which the entire length of the wave could be repeated in 1 sec. (Fourier polynomial, harmonic series). With the other method (Vercelli) the wave form is expressed as the sum of a set of sinusoids in the series 1, … in which the number 1 has the same meaning as in the harmonic series and the other numbers may stand in any relations whatever to the first one.
