How can i convert a digital signal to voice?

This is a loaded question....\n\nThere are many encoding schemes, some complex some not....\n\nBut basically, you have to know how the voice data is recorded first.  If it is simply a series of data in time scale encoded in amplitude only (for example, first data in the file representing the amplitude of the first instance, and the second representing the amplitude of the second), then you just have to sequentially read the bytes (or whatever the bit length) of the file and feed it into the D/A converter.  (Digital to Analog converter)\n\nBUT, I don't think the application would be that simple.  With today's audio boards and compression schemes, it could be far different.  \n\nYou have to study what digital data you are working with, and figure out what is required to reproduce the original data (voice)

there are some issues involve here\n\n1.- you can do that with a very technical program named MatLab (explain how to do it will be like a 15 pages explanation)\n\n2- what kind of sound card do you have? some sound cards already have that kind of software includ like the creative ones...(Audigy is one othe ones I know)\n\n3- you can find some SW for free in the internet with some limitations.

There is more than one way.\n\nThe Vonage website has details (see source)

Well there are two parts to that...\n\nFirst: you need to record the sounds (i.e. your dictation) you can do that with the audio recorder that is part of windows or any of many freeware, shareware or commercial software... For voice nearly any thing will work. \n\nSecond you need to tranfer the audio file to a CD... this is where it gets tricky... how do you want to use the CD...  If you want to play the file on a CD player you will need to encode it as a CD... The newer versions of Windows Media Player can do that or you could find a find freeware, shareware or commercial software (there are dozens out there)\n\nIf playing the audio on a computer is okay all you need is cd-r (writer) drive and softwar to drive it the Drag and Drop cd writer that come with Windows XP should or you could get other software to do it...\n\nTo define the exact process I would need to know more detail about what you want to do and what hardware and software you have to work with...\n\nEnder

You can use cheetah audio converter or any program that performs audio files conversions.\n\ntry this site\n\nhttp://downloads-zdnet.com.com/3120-20-0.html?qt=audio+converter&tg=dl-2001\n\nhttp://search.yahoo.com/search?p=cheetah+audio+converter&fr=FP-tab-web-t&toggle=1&cop=&ei=UTF-8

download a audio converter. Go to download.com and type audio converter and you should able  to find some program there to help you. :D

you need a voice recognition program.  Good ones that can really differentiate diction are really expensive.

Your question is a bit unclear. Despite the fact i'll help you at my level best.\n\nAre you trying to record some digital sound signal from your laptop to the pc or vice versa? \nIf so simply use the sound cards (integrated or PCI i.e Creative Audigy) Line_In and Line_Out ports on them. The computer that receives digital sound signals should be connected with a supported cable to its Line_In, and the computer that transmits should be connected to the Line_Out. But you should remember to initialize your settings in accordance to parameters that would not create unwanted distortion (Noise Hiss..!) i.e use 50 percent volume on the master of your digital mixer and line out/in.\n\nMono Out? \nMono is only single effect on the signal, its really good for speeches but why do you want Mono. You could sometime set certain parameters to receive Mono Signals on your card if it supports such. But it is possible to recieve Digital Stereo signals and then convert them into Mono with software assistance (Nero Wave Editor).  It doesn't take much time to do that as well.\n\nMicrophone!\nYes, thisis required to collect all audio signals from the atmosphere and then route them to the digital path (if using the digital mixers). But if you are utilizing Microphones try good quality microphones that have the appropriate i.e FM mics. \n\nGood Luck!

There are various applications out there that will allow you to do this. Best applications out there are Skype (www.skype.com) and the Gizmo Project (www.gizmoproject.com). Both apps allow you to make phone calls for free from PC to PC, but there is small charge if you want to call to a landline phone.

More info is needed. \n\nWhat is the pass band frequency, what is the spectral content of the input signal. Ideally how steep do you want it?

I don't understand why you want to start with a FM signal, and then need to revert back to a FM signal....?\nIf you already intend to use a fibre optic cable, then why not just send your digital signals from surface to ROV?  \nThese guys may have some handy stuff to achieve this:  http://www.esssales.com/ifo/fiberoptic-kits.html\nI can't think of an easy method of converting PWM signals into a FM radio signal.....
