Morphing

What is morphing….. Morphing is a special technique that creates a smooth,

controlled transformation of one image into another.

Morphing is a special effect in motion pictures and animations that changes (or morphs) one image into another through a seamless transition.

DEFINATIONS VOICE means the sound or sounds uttered through

the mouth of living creatures, esp. of human beings in speaking, shouting, singing, etc.

MORPHING a special-effects process used in film or

video production in which persons or objects seem to change shape, form, etc. in a smoothly continuous series of images created in a digital computer

So we can say as

Voice morphing can be described as..

The animated transformation of one voice into another by gradually distorting the first voice so as to move certain chosen points to the position of corresponding points in the second voice.

For example With voice morphing technology integrated can

produce many different voices. In cases where the speaker identity plays a key role, such as dubbing movies and TV-shows, the availability of high quality voice morphing technology will be very valuable allowing the appropriate voice to be generated (maybe in different languages) without the original actors being present.

3 inter-dependent issues for building voice morphing system? Developing a mathematical model.

Identify speaker

Type of conversion function

IMPORTANT TERMS RELATED TO VOICE MORPHING ARE AS FOLLOWS:- Target speaker. Current work is focused on extending the

techniques to allow the conversion of an unknown speaker's voice to sound like that of a known target speaker.

Voice acting is the art of providing voices for animated characters (including those in feature films, television series, animated shorts, and video games), doing voice-overs in radio and television.

Voice Changer now gives you the ability to remain totally anonymous when making phone calls.

What voice morphing can do???

changes like :- Young to old female to male old to young male to female robot helium

Aim for this invention The aim of this research is to develop flexible high

quality algorithms which can morph speech from one speaker. A system has been developed which uses special feature encoding and linear transforms.

To ensure high quality, a number of novel techniques have been developed to minimise the artifacts which typically result from loss of source information, formant bandwidth broadening, phase incoherence and spectral coloring of unvoiced sounds

Operative details for voice morphing:

Platform and development tools: Windows XP, MS Visual NET

Development technologies: C++, VST SDK 2.3.

External Libraries: FFTW2.1, Libsndfile, WinPthreads

For this we need Voice controlled instruments

WahWactor Input data: Control (e.g. voice) audio stream Audio stream to process (e.g. synth, guitar)

Output data: Processed audio stream

Benefit of voice morphing Emotional speech synthesis Speaker adaptation (mimicking voices) Speaker interpolation (mixing voices) producing voices Multilingual speech synthesis Singing voice synthesis Audio-visual speech synthesis Human motion synthesis
