  • SURFACE MOUNT SOLAR CELL WITH INTEGRATED COVERGLASS
    Publication number: 20170345955
    Abstract: Photovoltaic cells, methods for fabricating surface mount multijunction photovoltaic cells, methods for assembling solar panels, and solar panels comprising photovoltaic cells are disclosed. The surface mount multijunction photovoltaic cells include through-wafer-vias for interconnecting the front surface epitaxial layer to a contact pad on the back surface. The through-wafer-vias are formed using a wet etch process that removes semiconductor materials non-selectively without major differences in etch rates between heteroepitaxial III-V semiconductor layers.

  • Dynamic modification of automated communication systems
    Patent number: 9794405
    Abstract: A dynamically updated script for an interactive communication is generated during an interactive communication. The interactive communication is monitored over a communication network using a computer with a processor and memory for input during the interactive communication. When an input incompatible with an original script for the interactive communication is detected for the interactive communication, a dynamically updated script different from the script is generated in accordance with a type of the incompatible input.

  • System and method for prompt modification based on caller hang ups in IVRs
    Patent number: 9756183
    Abstract: In a method for use in Interactive Voice Response (IVR) systems, an IVR is configured such that voice prompts provided to a caller vary systematically and caller hang-up activity is attributed to the particular version of a prompt played to the caller. Voice prompt modifications are chosen based on how long the caller willingly listens to the voice prompt. A relatively short time listening to a prompt before hang-up, indicates dissatisfaction with that prompt. The system compares caller hang-up rates for each of the phrases in a prompt and chooses the optimum solution, which is the variant of the prompt with the longest caller listening time. Optionally, the system compares hang up rates to a threshold and contingent on that comparison chooses an alternative version of the prompt.

  • SYSTEM AND METHOD FOR INTELLIGENT LANGUAGE SWITCHING IN AUTOMATED TEXT-TO-SPEECH SYSTEMS
    Publication number: 20170236509
    Abstract: Systems, methods, and computer-readable storage media for providing for intelligent switching of languages and/or pronunciations in a text-to-speech system. As the system receives text, the text is analyzed to identify portions which should have speech constructed using a pronunciation distinct from the remaining portions of the text. The text-to-speech system uses multiple pronunciation dictionaries to generate and produce speech corresponding to the text, where the identified portions of the text are in a different language or have a different accent from the remainder of the text. Having generated speech corresponding to the text in multiple languages, accents, or dialects, the system combines the portions, then communicates the speech to the text recipient.
