becoz persons voice s very different from other animal . so voice is converted to electrial signal
NO

The instrument that converts electrical energy to sound or image signals in a radio or television is called a speaker for sound signals and a screen or monitor for image signals. These devices receive electrical signals and convert them into audible sound waves or visual images for the viewer.
A microphone typically uses electrical energy to convert sound waves into electrical signals. The electrical signals can then be amplified and processed by audio equipment for recording or broadcasting.
Sound is turned into electrical signals by a device called a microphone. Microphones convert sound vibrations into electrical impulses that can then be processed or recorded by various electronic devices.
The electrical signals generated by the ears are sent to the brain via the auditory nerve for interpretation. The brain processes and interprets these signals to create the perception of sound.
Microphones will convert sound waves into electrical signals. An ear (i..e human ear) will also convert sound waves into electrical signals.
Fiber-optic communication refers to the transmission of information using optical fiber. Opto-electronic repeaters are used to convert fiber optic light transmissions to electrical signals.
Binary packets
An antenna functions to receive electromagnetic signals from a transmitter and convert them into electrical signals for a device to process. It also transmits electrical signals from a device into electromagnetic signals to be sent to a receiver.
The retina is the part of the eye that contains cells called photoreceptors (rods and cones) that convert light images into electrical signals that are then transmitted to the brain through the optic nerve.
Alexander Graham Bell's telephone worked by converting sound waves into electrical signals, which were then sent through wires to a receiver that converted them back into sound. The telephone relied on the principles of electromagnetism to transmit and receive these electrical signals, specifically by using a metal diaphragm and an electromagnet to convert sound waves into electrical signals and vice versa.
