I have this problem too. Im trying to connect AV voice changer diamond 7 with skype yet when i call my friends they can hear my normal force and a kind of echo of the morphed voice instead.After finishing the voice settings for AV Voice changer youre supposed to select VAD mode in the AV settings ,and then select the VAD driver in the Audio settings in Skype, however when navigating my Skype Audio settings and choosing my microphone setting, the 'VAD driver' does not come up as an option when running the AV voice changer program.
