IMHO there is no such thing as you think (i assume i know what are asking about) - this is not trivial functionality also not sure about legal status for such software - something that can change human voice to for example help make crime is probably forbidden. For example this guy can know more - perhaps you should ask him: Something that can perhaps do some limited voice change is a thing (software or hw device) named vocoder. Also perhaps something like voice synthesizer can be useful for you - some of them are quite fancy (they can sing as famous Vocaloid - one of typical use cases is Hatsune Miku project or project Diva example voice synthesis by Voiceroids+ ). Oh, nowadays government can do whatever it want to protect citizens and for citizens own good. Guys - i know, my English is far from being even mediocre however i only suggested to verify legality not made statement that is is illegal. We have chance to live in strange times. Still a ridiculous assumption and statement.

Find Voice Imitation & Recognition software downloads at CNET Download.com, the most comprehensive source for safe, trusted, and spyware-free downloads on the Web. From Voice Imitation & Recognition: Imitate voice of one person into any person voice in such a way that a second person voice shall be heard speaking in the same voice as the first person. This powerful tool is based on robust algorithms that provides flexible vocal files process, which brings new concept to the dubbing post production sound effects.

You can sugarcoat it and back-peddle all you want.owning software that disguises your voice is not illegal and has never been illegal.period. 'Voice impersonator/spoofer software' do you understand term impersonate - spoof? This is something else than change - at least for me. And at the end - what is point of this discussion - falsifying money is a crime, falsifying someone undersign is a crime - IMHO falsifying someone voice that can be used as undersign can be a crime too. There's lots of software that will alter a voice to make it sound 'different'.

What the OP is looking for is software that will make a voice sound like a specific other person's voice. That's a completely different class of problem. That would have to change the timbre of the voice, the accent, inflections, pitch, timing, etc. The accent, inflection, timing and mannerisms is the responsibility of the user to imitate which I don't mind. No program can realistically do that. If the software can accurately make me sound like Britney Spears but I was talking fast, I should expect a fast-talking Britney Spears, same thing if I was mumbling. The pitch and timbre is something the program should look at it, but they aren't the only qualities in what defines a voice.

I dunno what timbre is, the definition came off to me as 'anything that makes a sound at the same pitch and loudness still different' which is vague. I'm amazed with the advent of spectrographs that nothing like this exists. I tried making my voice the same pitch as a child's and examining them both with a spectrograph and noticed that the child's voice is not only a higher pitch but has fewer frequency bands/harmonics. Is this what timbre is? Even then there's more to this as AV Diamond failed to make my voice anything near any of the voice samples. Also, voice emulation illegal? Made me snicker at some of you paranoid weirdos on here.

The closest to your claim is identity theft, when it involves spending someone else's money. Even if what you said is true, who the. would prosecute me for impersonating a fictional character? And at the end - what is point of this discussion - falsifying money is a crime, falsifying someone undersign is a crime - IMHO falsifying someone voice that can be used as undersign can be a crime too. Finding a bank card with the PIN number written on it and never using it is NOT a crime moron.and neither is owning or using voice altering software. I'd imagine you would have my ex-girlfriend arrested for her deviate tactic of having her brother record the message for her answering machine since she didn't like the voice-altering software that came with her answering machine?

Maybe you would have her brother arrested too?

Maybe you would have her brother arrested too? Maybe this will clarify a few things. There are a class of DSP devices & algorithms known as 'formant processors' that specifically work on what you guys are referring to as 'timbre', which have to do with the resonances & harmonics (and the groupings of their dynamics relative to the fundamental frequencies) of sounds.

Certain, more-complexly-designed pitch changers actually include formant processing (unlike the simplified statement of the OP), so one CAN change their OWN voice to a different pitch or to THE SAME PITCH, but sounding like a child, (and many other possibilities). There are even experimental formant processors, matched with vocoders & ADR processors that do allow one to 'replace a voice with someone else's' on the same phrase of text. I know this because in the early '90s I did research on this very thing. However, it wasn't then, nor is it now, a feature that is ready-for-prime-time, because there is much more to the 'uniqueness' of one's voice than just formants: pacing & prosody & stresses, and accent.

I was intending to create a unified processor that would work on ALL those factors (using midi, TTS, speech recog, LPcoding, etc), but there is still too much of real world variations that one cannot deterministically pin down for a dumb computer to work with. (Unless there is some secret military/government stuff out there.) Now, if that were available commercially, it would not necessarily be 'illegal' just as other devices that COULD CONCIEVABLY be used to impersonate an individual are not. It is the actual attempt or perpetration of the impersonation (done non-consensually) that is illegal. However, I can easily see governments banning certain algorithms or devices, if their SOLE PURPOSE was explicitly to impersonate (it has already happened before - ask me sometime about 'signature pads'). But who's going to be stupid enough to market something that way?

And there is a vast difference in QUALITY between 'impersonation' and 'emulation'/ 'matching'. The former might fool a general human audience, but probably not if one were to hear the same phrase spoken in A/B back-to-back comparison with an original. The latter WOULD fool an audience and probably a pattern-matching algorithm on a computer security-check. So the former would probably NEVER become something involved in a identity theft case, yet the latter could. So, to answer the OP, if you want to try one of those more complex pitch-shifters that include formant processing, go for it. Otherwise, don't hold your breath.

Are you back for another beating, or just attempting to get the last word in? Don't smoke or drink to much - this not very healthy especially for brain - 'last word' - this is your country? Why you attacking me for having such law? Read once again my first reply in topic - i just recommend to check local law because some aspects can be illegal - that's all.

But obviously you have serious problems with reading - how they say this in U.S.? You are a bit challenged Have a nice Christmas wherever you are now. Even bigger list: have fun!

Why you attacking me for having such law? Your country has this law? Show it to us.

Show us ANY LAW in any modern, civilized country that has such a law. Any language.any country. SHOW US or shut up. You are hilarious. I'm not a lawyer, i'm not interested to imitate any voice then why i should start analyzing law to find potential regulations?

- if you are interested go and find this your self. I don't wanna start talking about 'modern, civilised' countries laws - DMCA is less than 20 yrs. And i can show you middle finger if you want (i assume not) however if you need knowledge about such law (if that law exist or not) ask lawyer and pay for his work. Hope the rest of you were able to celebrate the holidays, I couldn't without making the rest of my family sick. The fat bearded bastard dressed in red gifted me the flu this Christmas. Using my voice now is out of the question since I can't speak with clarity. Pandy, I tried the voiceroid+ from the vocaloid line of products and I thought it was very interesting, this is the best text-to-speech I've ever used, but it only speaks Japanese and the video I'm dubbing is in English, so it can't do.

I never intended to use text-to-speech to begin with, but I'm willing to try now since I can't use my voice. All other popular products I tried only were cable of producing those crappy robotic voices. Anyone know where to get a free download of CereProc? I heard one of the authors recently lost their voice and reprogrammed the software to obtain his voice profile from past recordings and successfully rebuilt his voice. Cornucopia, thanks for all the info. No I don't need a perfect, unfalsifiable clone of the voice, just enough so it doesn't sound off-key when people are watching the movie where the cloned dubbed lines will be surrounded by the real voice of the character.

You say I need a formant processor. Any specific software you recommend? No pandy, it can speak a colossally retarded version of Engrish and that's the closest it gets.

I've fed it your own post in the MP3. On second thought, I doubt the viability of Voiceroid even if it could speak English and let me make a custom voice. It sounds very monotoned and unnatural. Text to speech won't do, I'll have to investigate formant processors until I get well. Huh but it is like forcing native Japanese speaker to speak English - i agree that this kind of voice will be quite odd however i believe that speech synthesis model is identical to all humans - this is proof how with relatively simple devices human voice can be recreated - IMHO making custom voice (voiceroids) is possible - issue is that You need probably need a lot of knowledge about human voice and having this knowledge you will probably not start this topic.

TTS apps usually make use of stock Windows (or similar) TTS engines, which are years behind what COULD currently be available (and what you would be wanting). They have limited inflection & prosody (though the Win7/8 models are MUCH MUCH better) and the formant richness is still lacking. XP's were just 3 or 4 nodes, Win7 is like 5. Art cam 2009 viktar bitmap.

It takes like 7-9 nodes (my term) before it actually sounds human. And that still doesn't follow accent rules or particularly smooth pacing. And that is still only just a 'stock' voice. IOW, like I already said: Not yet ready for prime-time!
