We need a speech enhancement module for Windows XP/Vista/7 (32/64 bit) for langauge examination. Each candidate wear a headset which has microphone #2 on one ear piece (for recording the neighbour candidate speech and environment sound) and microphone #1 (for recording the candidate's own speech). Both microphones #1& #2 will connect to a usb sound card (cmedia 6206 chipset) with two microphone inputs. We need the speech enhancement module can use microphone #2 's recordings as reference to filter these noise/sound from microphone #1's recording so to deliver a clear and silent speech recording for exam assessment.
Since we already made own sound card driver so we just need a module to compare and filter the neighbor speech and environment noise.
Note: environment noise in general not much but neighbor speech quite much because candidates are sitting close.
