  • IVR interactive voice response
  • IVR systems allow telephone callers to interact with data processing systems. IVR systems are widely used by businesses to offer automated transaction services and/or automated information services.
  • An IVR system normally includes a computer which executes an IVR software application that interfaces a caller with a data processing system. The IVR system provides a sequential flow of audible prompts to the caller, and the caller provides speech and/or touch-tone input in response to the prompts over an established telephone call. Through this interaction, the IVR system collects information from the caller that can be processed by the data processing system to automatically provide a selected transaction and/or information service.
  • a caller In a telephonic IVR interaction. A caller first hears a welcome message spoken by the IVR system. Next, the caller is audibly presented with a menu containing a number of forms corresponding to services offered by the IVR system. The caller is requested to select one of these forms by speech and/or touch-tone input. The IVR system then branches to the caller's selected form.
  • the IVR system audibly presents a sequential flow of data fields of the selected form to the caller, and the caller sequentially fills each field by speech and/or touch-tone input.
  • the IVR system asks the caller if they wish to modify the filled form. If the caller wishes to modify any of the fields of the filled form, the IVR system returns to selected form and sequentially repeats the fields. If the caller does not wish to modify the filled form, the IVR system interacts with a data processing system to process the filled form to provide the caller's selected service.
  • prior art telephonic IVR interactions have no perceivable persistence in that the sequence and content of the data fields and the caller's speech and/or touch-tone input are not visible to the caller during the interaction.

Abstract

L'invention concerne un procédé et un système permettant de naviguer et d'éditer des informations téléphoniques de réponse vocale interactive (IVR). Des champs de données provenant d'un système IVR sont présentés de manière audible à un appelant téléphonique. Chaque champ de données est associé à un identificateur unique. Un mode d'édition est également présenté de manière audible, à partir du système IVR, à l'appelant. Au cours du mode d'édition, l'appelant peut fournir une entrée vocale et/ou clavier correspondant aux identificateurs uniques respectivement associés aux champs de données afin de naviguer de manière sélective, individuelle et non séquentielle dans des champs de données; de restituer des champs de données de manière audible; de fournir des entrées dans les champs de données; de restituer de manière audible une entrée dans des champs de données; de modifier une entrée dans des champs de données; et de confirmer une entrée dans des champs de données.
