Welcome to the world of Scilab Speech--Talk With Scilab

　Research on man-machine conversation has become more and more popular. Doctor Yonghong Yan said, "In the future, human beings may even not see computers when they communicate with computers. You can control the computers and wireless equipments even if you sit on sofa or lay on bed." With the popularization of wireless communicating equipments , developing a human and machine speech communication system in the mobile phone, PAD and robot is becoming applicable. In this situation, more and more company focus on the design of the human and machine speech communication system. There have been some famous voice systems being developed such as the "voicecommand" which is designed by the Microsoft, the "IBM Viavoice" which can operate personal computer by voice command and the speech synthesis system "interphonic" which is developed by USTC iFLYTEK CO. However many users and researchers are not able to use the above systems due to their expensive price, no source code and the lack of providing speech analysis functions. So we have developed Scispeech, which is an open sourced speech analysis, synthesis and recognition toolbox especially designed for Scilab. The SciSpeech toolbox can be easily used or extended by scholars who is doing research in the realm of speech analysis, synthesize and recognition.

　SciSpeech provides various analysis functions including time analysis, frequency analysis, cepstral analysis and WRLS-VFF analysis, which provides great convenience for the both developers and users, while the famous software MATLAB voicebox toolbox only offers few speech analysis functions,

　SciSpeech use the PSOLA algorithm to supply the prosodics adjusting function in the module of speech synthesis. And this complex function is open sourced so that it can be easily applied and modified in a speech synthesis system.

　SciSpeech also includes a practical speech recognition system, which can recognize speech command within a short time and the telephone number recognition ratio is very good. Our system implement the function of speech dialing, it can also shut down, restart and logoff the operating system and open the help of scilab. In fact it contains our open source versions of “speech command” and “speech dialing” functions provided by the "IBM Viavoice" that developed by IBM, which is the fundamental functions of IBM Viavoice.

　 With SciSpeech, you can talk with scilab freely. Now let's begin the wonderful trip with SciSpeech.
