A telephonic therapy training device usable by speech-impaired persons and/or hearing-impaired persons to improve their telephone usage skills. The device is a "learn-by-doing" device wherein the instructor and each student are provided with individual handsets, each of which includes a microphone and a speaker (receiver). Each voice signal is sent through a microphone into an individual amplifier that transmits an amplified signal to an opposite party receiver in the individual handsets. The training device operates on regular household current; the use of commercial telephone lines is avoided in order to escape telephone service fees.
