How to set a voice password for my Windows 7 Ultimate laptop to access and shutdown? Recommend me the best software for this.
There are some services like VoiceVault that offer voice biometrics, but Microsoft doesn't allow by default voice log-in because it's very easy to bypass.
Consult the VoiceVault website for more information: https://support.microsoft.com/en-us/kb/78792
Secondly, use a face recognition software to log-in which is harder to crack and also easy to set up: http://www.sensiblevision.com/en-us/products/forhome/windows.aspx
