Mobile phones are playing an important role in changing the socio-economic landscapes of emerging economies like India. A proper voice-based user authentication will help in many new mobile based applications including mobile commerce and banking. The authors present their exploration and evaluation of an experimental set-up for user authentication in remote Indian villages using mobile phones and user selected multilingual spoken passwords. They also present an effective speaker recognition method using a set of novel features called Compressed Feature Dynamics (CFD) which capture the speaker-identity effectively from the speech dynamics contained in the spoken passwords.
