A system enables voice authentication via a network. The system may include an intelligent voice response engine operatively coupled to the network for receiving transaction or access requests from a plurality of telecommunications devices over the network. A speech recognition and verification services engine may be operatively coupled to the network and a database may be operatively coupled to the speech recognition and verification services engine for storing user voice print profiles. The speech recognition and verification services engine may receive a speaker verification call from the intelligent voice response engine and perform speaker verification on the received speaker verification call based on the stored user voice print profiles. The speech recognition and verification services engine may generate a verification score based upon results of the speaker verification.
