An ARU converts data/ information from the computer memory (which is in electronic form) through various specialized additional circuitry into waveforms/ sound for the receiver to hear.
The sound can be spoken language, musical notes or beeps. This output is obviously Softcopy.
Voice output is useful where reading is not necessary or is impossible and where fast output is required.
For example, Voice output is used:
- As a learning aid.
- In emergency situations for messages.
- In answering services, e.g. Post office talking clock.
When an ARU is used to produce speech, it is called a Speech Synthesizer.
A Speech synthesizer is a useful form of output especially when communication with a computer is made using telephone lines. A user dials the computer & makes an inquiry. The computer output is passed through the Speech synthesizer, which is located near the computer. The output is converted to a spoken reply, which is sent to the user over the telephone line.
