I need software that is compatible with WINDOWS 7 PROFESSIONAL. The software will change any voice to a male or female British accent. It must work on SKYPE and YAHOO MESSENGER. I use SKYPE [url removed, login to view], the final version of SKYPE 4.2 and I use YAHOO MESSENGER 10. The software must be compatible with both the microphone and speakers on my SONY VAIO laptop and the MICROSOFT 3000 CHATMATE headset I use, both microphone and earphones.
