[b] [/b]Hi am MOHAN i would like to get details on face morphing technical seminar ..My friend TUSHAR said face morphing technical seminar will be available here and now i am living at BHUBANESWARand i last studied in the college/school GANDHI INSTITTE FOR TECHNOLOGY  and now am doing MCA i need help on SEMINAR TOPIC FACE MORPHING

Abstract

Voice morphing means converting a speech signal into another. Morphing as the image, aiming to maintain a smooth transition between morphing speech, starting and maintaining the shared characteristics of the final signals Speech morphing is analogous to image morphing, while displaying images of these images, a face appears to easily change its shape and texture in the image unless it turns into a target's face. It is this characteristic that a speech should be near the vowel. A speech sign should be changed smoothly to another, the shared characteristics of the beginning and closing sign should be maintained, but the other qualities should be easily changed.

As far as speech is the key to worry about signal, its pitch and envelope information is. Both of these speakers live in a proven form in the signal. Therefore, to remove each of these, some effective method is necessary. We have adopted a simple approach, i.e. cepstral analysis The pitch and formant information in each signal is extracted using a seperate approach. The necessary processing for obtaining Morphed speech signals include transformation of the acoustic expression back into the acoustic wave to match the cross-discrete, dynamic time-warping of the envelope information with major signal characteristics (pitch) and signal re-assessment.

Introducing Morphing

Speech morphing can be obtained by changing the representation of the signal from the acoustic wave received from the sample of analog signal, with which many people are familiar, for the second representation. To make the signal for change, it is divided into several frames - the square of the wave. Then the conversion applies to each frame of the signal. This signal provides another way to see information. The new representation (stated in the frequency domain) describes the average energy present on each frequency band

Two pieces of information can be obtained in the further analysis: pitch information and the overall envelope of the voice. An important element in morphing is the manipulation of the pitch information. If two signals with separate pitches are simply cross-feeds, then it is very possible that two different sounds will be heard. This happens because there will be two different pitches in the signal, so that the auditory system will experience two separate items. Should display a smoothly changing pitch in a successful form

The pitch information of each sound is compared to providing the best match between the pitches of two signals. To make this match, the signs are enhanced and compressed so that the important section of each signal is found on time. The interpolation of two sounds can be performed, which makes intermediate sounds in the form. The last step is to then convert the frames to the normal wave.
