ABSTRACT:
In a method of and a system for determining the variation of a speech parameter, for example, the pitch, in a speech signal, values ms(i,j) and coupling vectors v(i,j) are calculated for time instants i and a number of values j of the speech parameter f.sub.j for each time instant i by means of an optimization algorithm. Of the values ms(m,j) associated with the last time instant i=m, the optimum (that is to say the smallest or, on the contrary, the largest) value is determined. By use of the coupling vectors, the variation of the speech parameter as a function of time can be obtained by means of a back-tracking procedure. In the calculation of the values ms(i,j), inter alia, a cost parameter k is taken into account which is a measure of the deviation of the speech parameter f.sub.j (i) at the time instant i with respect to a predicted value for the speech parameter at the time instant i.
