Method and apparatus for controlling the operation of an emotion
synthesizing device, notably of the type where the emotion is conveyed by
a sound, having at least one input parameter whose value is used to set a
type of emotion to be conveyed, by making at least one parameter a
variable parameter over a determined control range, thereby to confer a
variability in an amount of the type of emotion to be conveyed. The
variable parameter can be made variable according to a variation model
over the control range, the model relating a quantity of emotion control
variable to the variable parameter, whereby said control variable is used
to variably establish a value of said variable parameter. Preferably the
variation obeys a linear model, the variable parameter being made to vary
linearly with a variation in a quantity of emotion control variable.
