Best webcam for voice assessment

I want to do voice analysis though MATLAB code but my logitech camera is not giving good quality voice. Can someone please suggest a good webcam with bestest sound quality/audio quality for voice research

What specifications do you need? And do you need video at all, or just audio?

Sir, i want video for eye details. but want good quality audio/microphone integrated along for voice analysis using MATH code. can you please suggest USB camera with cord mic so that mic is closer to the mouth for better sound recording

As far as I can recall, none of the streaming video input routines support audio as well, so you might as well get a separate microphone. The input routine that I can think of that supports combined audio and video is only for files.
