An electronic speech therapy teaching apparatus for use by a speech therapist includes a silent timer with an associated electronic digital display, an adjustable aural speech rate device, an automatic calculator for computing a student's percentage of correct responses, an electronic display of the accumulation of total and correct responses, and controls to select and operate the various features of the apparatus. The silent timer selectively counts up or down, informing the operator when counting down, through an audio/visual alarm, when a predetermined time period has expired. The adjustable aural speech rate device produces tones at a rate appropriate for the speech student. Manually controlled switches enable the operator to register and display the number of correct and total responses during the evaluation procedure. An automatic computer calculates the percentage of a student's correct responses as they are registered by the operator.
