Systems and methods for bio-phonetic multi-phrase speaker identity verification are disclosed. Generally, a speaker identity verification engine generates a dynamic phrase including at least one dynamically-generated word. The speaker identity verification engine prompts a user to speak the dynamic phrase and receives a dynamic phrase utterance. The speaker identity verification engine extracts at least one voice characteristic from the dynamic phrase utterance and compares the at least one voice characteristic with a voice profile the generate a score. The speaker identity verification engine then determines whether to accept a speaker identity claim based on the score.

Call routing systems and methods are provided. A particular routing method comprises decoding a message based on an incoming call to determine whether a live agent is required. When a live agent is not required, a destination interactive voice response (IVR) application is identified, a determination of whether the destination IVR application is VoiceXML capable is made, and the incoming call is sent to the destination IVR application when the destination IVR application is VoiceXML capable. When the destination IVR application is not VoiceXML capable, a determination of whether the destination IVR application is capable of supporting an external data interface is made, and incoming call session data is routed to the destination IVR application when the destination IVR application is capable of supporting the external data interface. An audio file including one or more dual tone multi-frequency (DTMF) commands based on the incoming call session data is constructed and sent to the destination IVR application when the destination IVR application is not VoiceXML capable and is not capable of supporting an external data interface.
