How can I monitor speech flow?
-
I have been given a task which requires my program to be able to monitor (in realtime) a person speaking. In particular, I need to know when he starts and stops talking. The environment is that there is a dedicated microphone connected to a PC running WinXP and my "C" program (MSVC 6.0). Being a software person, I do not have much experience working with speech and sound. Any suggestions on how to do this? All comments and suggestions will be appreciated.

I haven't done much of the same, though you might want to drop in on the audio section here at CP, or if you have a full weekend download an open source audio project and use the source to teach you how. Try this project on fft for audio[^]. or visit several of the projects in the audio section[^] until you pick up the classes and knowledge you need. _________________________ Asu no koto o ieba, tenjo de nezumi ga warau.

I'm not sure much which way you want it. I hope you want to monitor voice continuously. if it is so , use the mcisendstring functions and API calls on windows to monitor the voice. regds.
Dear Anonymous, I don't understand what do you mean when you said which way you want it? I understand that I will need to monitor the sound continuously, so that I can detect the starts and stops of the speaker. Also, could you please expand on which mcisendstring functions and API calls I should examine because I need help and possibly don't know what questions to ask. By the way, I have used the mci functions to play sound and record, but signal analysis is something new to me.
