      Qt has no speech recognition APIs, your best chance is to look for a third party library, preferably a C or C++ one, since it is a performance critical task, and use that alongside Qt.

          What the problem with Windows SAPI? or you need speech recognition for over platforms? There is good examples in Windows SDK for programming with SAPI.

              Windows SAPI is only for windows and windows ce, you can't use them for Symbian. Anyway, you can find SAPi samples here: http://msdn.microsoft.com/en-us/library/ee125103(v=vs.85).aspx

                  Have no idea about Symbian, but where is some simple GPL'd projects, maybe you can use some of them. For example "Open Mind":http://freespeech.sourceforge.net/

                    It will be sweet sunny day, when I will contribute Qt. I will work on QtInteractive module (face recog, speech recog).

                    But now it's only idea.

                        We in Digia are working with Nuance to get this plug in working well in Qt. We have a demo that is using speech recognition. If you are interested in this, please contact us, and we can see what we can do to help you :) contact me directly, or send an e-mail to qt.info@digia.com
