amplitude . . . . . makes the sound louder or softerThe sound of an explosion across the street has higher amplitudethan the sound of a cat across the street.frequency . . . . . makes the pitch of the sound higher or lowerThe sound of a little girls voice has higher frequencythan the soundof a big man's voice.
The BMW navigation system uses stored sound files of a computer generated voice.
EVERYONE has a singing voice! Just alot of people can't really make there voice the way they want it to sound.
sound waves...... <3
This is echo.
Voice-Over-Internet Protocol... VoIP allows you to make telephone calls using a computer network, ... VoIP converts the voice signal from your telephone into a digital signal.
Actually you have this backwards, the telephone lines can only carry analogue signals (voice band, 20Hz to 3KHz) not digital signals.The device that converts digital signals to analogue signals for transmission over telephone lines is called a phone MoDem(this stands for phone modulator demodulator). At the opposite end of the line it of course converts the telephone analogue signals back to digital signals.
Sound (speech) to digital information and back. VoIP stands for Voice Over Internet Protocol.
Hi The sound is converted from analogue signal into a digital format and then transmitted with other digitized voice signals across the fibre. Next the digital signal are separated and converted back to analogue signal. regards Philip
Voice IP is a voice signal converted to digital signal and pass through internet to reach other contact.
When you speak into a cellphone an analog to digital converter chip converts your voices sound waves into a digital signal. Then a digital signal processor compresses the digital signal. The compressed digital signal is then transmitted as a radio wave through the cellular network. The digital signal processor on the receiving end, decompresses the incoming message, an amplifier boosts the signal to make it loud. Then its passed to the speaker. The end............ DJ
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.
Familiar examples include audio and video signals resulting when a microphone converts voice or a video camera converts an image into an electrical signal. By contrast, the digital signal takes only a few discrete values. In the binary representation
DSP -Digital signal processing the word it self says it is process of analyzing the digital signal . The system which does this work of analysis is the digital signal processing system. In this system the raw analog signal(ex:human voice) which is time domain signal is fed to the pre aliasing filter which removes noise part of the signal and this fed to the sampling and quantization in which the real time analog signal is discretized and digitized . After this process this digitized signal is fed to the DSP processor to do the specific operation on the signal (ex: convolution , modulation etc.,) .This processed signal is fed to the D/A which converts the digital signal to the analog signal real time signal. after all explaining the process of signal processing. the stages between the sampling and D/A is the digital processing system.
VoIP needs a converter or host that will converts voice signal into digital signal. You still need to subscribe a connection from VoIP service provider. Different providers can be found in pbx101.com.

VOIP is most commonly used terminology now-a-days which stands for "Voice over internet Protocol", which uses broadband internet rather than the public switched telephone network (as in traditional phone services). The basic steps involved in originating an Internet telephone call are conversion of the analog voice signal to digital format and compression and translation of the signal into Internet protocol packets for transmission over the Internet.Visit www.voipnetcompare.com for more information, deals and questions about VOIP.
