To minimize the distortion of analog signals during transmission
Because digital lines transmit signals more efficiently across distances than analog lines
Because many telephone networks are moving over to digital interfaces
The only way is to digitize the audio signal and send it as data
You would utilize a VoIP adapter in the conversion of analog voice signals into digital IP packets. These adapters also have the ability to convert digital IP packets into analog voice streams.
yes!
The human voice is an analogue signal because the frequency of the sound varies in the sound waves as well as their amplitude that gives the power. Analog signal is defined as a signal that has a continuously varying amplitude or frequency. Human speech, and everything else a human hear, is in analog form.
The data rate for Pulse Code Modulation (PCM) digital voice signals is calculated using the formula: Data Rate = Sampling Rate × Bits per Sample. For standard voice applications, the sampling rate is typically 8 kHz (samples per second), and each sample is represented by 8 bits (1 byte). Thus, the calculation is 8,000 samples/second × 8 bits/sample = 64,000 bits per second, or 64 Kbps. This rate is sufficient to capture the frequency range of human speech effectively.
Voice signals are analog signals, whereas computer signals are digital .

becoz persons voice s very different from other animal . so voice is converted to electrial signal
A current flows in telephone wires primarily to transmit voice and data signals. When a person speaks into a telephone, their voice is converted into electrical signals, which travel along the wire to the receiving end. This electrical current allows for the modulation of signals, enabling clear communication over long distances. Additionally, the current is necessary for powering components like the telephone's ringer and signaling functions.

Voice Communication is Interexchange of Voice that is Capturing Sound to Electric Signals and Generating Sound from Electric Signals. Voice Communication needs both Input Device (Microphone) and Output Device (Headphones\Speakers). Broadcasting Voice Communication entirely depends on Output Devices at Audience Side.
all the signals can not be categorized as even and odd,signals like voice we can not categorize it as even or odd either we can say it is a complex signal.

VOIP means Voice over Internet Protocol. Basically, voice signals traversing over the Internet.
It's a device that converts hand writing or drawing to digital signals usually with a stylus or pen. Good for writing Chinese or Japanese characters. It's another way of inputting data or commands to a computer.
A microphone converts voice sound waves into electrical signals, which are then digitized by an analog-to-digital converter (ADC) to produce digital signals. These digital signals can then be processed and transmitted digitally.
Headphones or speakers and a microphone. Whatever program that is providing the voice chat could also be considered a necessary device.
