A media handler is used in a transaction processing system, where the system is configured to route incoming calls from callers to agents associated with the transaction processing system, and the incoming calls are based on voice-mode communication and text-mode communication. The media handler includes a media translator operatively incorporated into the transaction processing system and configured to facilitate translation between the voice-mode communication and the text-mode communication. An agent preference setting is selectable by the agent between a voice-mode and a text-mode. Also included is a speech recognition unit configured to convert the voice-mode communication to the text-mode communication and a speech synthesizer configured to convert the text-mode communication to the voice-mode communication.
