Abstract
Audio/speech-based and text-based interactions between a transaction terminal and a user conducting a transaction are provided. In an embodiment, the terminal may establish a direct wireless connection to a user-operated device or an indirection wireless connection to the user-operated device through a proxy device. In an embodiment, the wireless connection is automatically established through a different out-of-band wireless communication between the terminal and the user-operated device. In an embodiment, text-based data for the transaction are provided over a second simultaneous wireless connection that is different from the wireless connection associated with providing the audio/speech data. In an embodiment, audio/speech data provided from the user during the transaction are enhanced for security and are filtered for accuracy using audio-based processing and/or image-based processing. In an embodiment, a speech-to-text and text-to-speech interface for a transaction at the terminal is provided.
