  • Publication number: 20180133900
    Abstract: A social robot provides more believable, spontaneous, and understandable expressive communication via embodied communication capabilities by which a robot can express one or more of: paralinguistic audio expressions, sound effects or audio/vocal filters, expressive synthetic speech or pre-recorded speech, body movements and expressive gestures, body postures, lighting effects, aromas, and on-screen content, such as graphics, animations, photos, videos. These are coordinated with produced speech to enhance the expressiveness of the communication and non-verbal communication apart from speech communication.

  • Patent number: 9131049
    Abstract: A telephone call is connected through a caller transfer point in a PSTN to a call recorder in a private hosted telephony network for making an audio recording of the telephone call. The telephone call is also connected from the caller transfer point through an IVR transfer point in the PTSN to a remote IVR server for dialog processing of the telephone call. At some point during the dialog process the connection between the call recorder and the IVR transfer point is placed on hold while maintaining a live connection between the call recorder and the caller transfer point. A human agent is then connected through the IVR transfer point to the telephone call for further handling of the telephone call, and the connection to between the IVR transfer point and the call recorder is restored to allow communication between the caller and the human agent.

  • Patent number: 8824663
    Abstract: The present invention provides a system, method, and computer program product for automatically detecting any unnecessary repetition by customers of specific types of information in a multi-channel (e.g., self-service application, IVR system, live agent center) customer service session. For each channel used in the customer service session, the information provided by the customer in the channel is recorded in a log, transcription, or other record. The record(s) for the customer service session are subsequently parsed for specific types of information provided by the customer. From the parsed records, specific types of information provided by the customer in two or more channels during the customer service session are identified. In one embodiment, the results are analyzed to determine if providing such information in two or more channels is redundant, and, if so, this is counted as a redundancy.

  • Patent number: 8761373
    Abstract: A system and method is provided for automatically generating an interactive voice response (IVR) application flow from recorded audio files of calls to or from an IVR system. The method includes identifying an IVR state sequence for each of a plurality of calls from recorded audio files of the calls. The N most common state sequences are identified for the IVR system for the plurality of calls. An application flow is then displayed for the IVR application using the N most common state sequences.
