simulated laughter through the installation of the robot system can simulate human vivid laughter

different computer analysis of human laughter tone, flow, time and frequency table

Scientists say such an act of human laughter may be formed millions of years ago. For us, in fact, seem to us ordinary laughter a lot of hidden information transmission. On the one hand, we laugh a lot of different tones, from \On the other hand, our laughter has a different rhythm, rhythm and intonation, and the details of these different changes through our tongue and facial muscle contractions in different locations and degree of control of access and speed of airflow to achieve.

These details help us to convey different, such as warm smile, good laugh, nice smile, helpless smile, sneer, Yin Xiao, and laugh at the different emotions, but also help us determine the issue of laughter human voice hidden mood changes. Human laughter is a natural emotional changes in the behavior under the subconscious. Therefore, if one fake smile, the other will be aware of,[link widoczny dla zalogowanych], but could not say on what basis that the other is fake smile. This is because laughter is a subconscious act and,[link widoczny dla zalogowanych], therefore, be distinguished on the subconscious level of authenticity. This feature helps to laugh a group unconscious internal solidarity, but also can be used as a weapon of foreign competition.

Germany, Saarland University researchers Bulv Ken Jurgen and his team for the robot to imitate human laughter launched a research project. Them through the construction of different models to simulate the channel and flow of human movement, using computer programs to produce different types of laughter and a different channel bionic air model for voice synthesis, so that simulated laughter sounds more natural.

the same time, Pierre Curie, Paris, France, Professor Greg University study concluded by a set of acoustic algorithms, when the computer voice to text to speech software, the use of this algorithm to change the acoustic one of the beat and rhythm to convey the same under different emotional words.

Gregory Professor Jurgen use of acoustic algorithms, combined with the German telecommunications company,[link widoczny dla zalogowanych], the linear predictive speech coding technology, and his laughter channel flow simulation model, synthesis of a variety of techniques to eventually build that can issue almost identical to human laughter laughter laughter simulation systems, robotics simulation of laughter through the installation of such systems, different emotional signals can be received, analyzed and given a different laugh.

Recently, researchers have also established a special online \What is the machine simulated laughter. This interesting Web site is [link widoczny dla zalogowanych] interested, you can go to Test your hearing.
