  • Patent number: 8229746
    Abstract: Disclosed herein are methods and systems for recognizing speech. A method embodiment comprises comparing received speech with a precompiled grammar based on a database and if the received speech matches data in the precompiled grammar then returning a result based on the matched data. If the received speech does not match data in the precompiled grammar, then dynamically compiling a new grammar based only on new data added to the database after the compiling of the precompiled grammar. The database may comprise a directory of names.

  • Patent number: 8204205
    Abstract: The problem of an automated telephony system having only a single way to measure a caller's difficulty in processing a transaction when using the system is solved by selecting from at least two thresholds for measuring the caller's difficulty. Having a choice of alternative thresholds to measure the caller's difficulty, referred to as inefficiency thresholds, allows for a more responsive approach to managing an automated telephony system. This choice of inefficiency thresholds overcomes multiple problems of systems only using one inefficiency threshold, such as: (1) transferring a call to a live agent to quickly, (2) transferring a call to a live agent to slowly, and (3) giving a caller a feeling that the automated telephony system is unresponsive to his or her needs. Having multiple inefficiency thresholds from which to choose allows for a more dynamic response to a diverse audience of callers and to different needs of a single caller during the various parts of a call.

  • Publication number: 20120148032
    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.

  • Patent number: 8176937
    Abstract: A temperature adjustable water mixing valve having a cold water inlet, a cold water outlet, a hot water inlet, a mixing water outlet, and a valve core configured to open or close water channels. The temperature adjustable water mixing valve further includes a pressure relief channel between the cold water inlet and a port connected with a water storage device. The channel is equipped with a check valve allowing water to flow from the water storage device to the cold water inlet. The temperature adjustable water mixing valve opens the check valve to discharge toward the front-end water source when the inner pressure in the water storage device is high.

  • Patent number: 8024179
    Abstract: Disclosed are systems and methods for dynamically interacting with a user through a spoken dialogue system. A method includes the steps of (1) receiving a user utterance, (2) analyzing the user utterance for a threshold determination of dialect, (3) generating a response that reflects an incremental implementation of the dialect, (4) further varying the perceived implementation of the dialect in subsequent responses by a process of: (a) receiving a subsequent user utterance, (b) determining a modified level of confidence in the dialect based at least in part from the subsequent utterance, (c) generating a subsequent response that implements an incremental variation according to the modified level of confidence.

  • Patent number: 7794959
    Abstract: The present invention relates to the discovery that specific human taste receptors in the T2R taste receptor family respond to particular bitter compounds present in hydrolyzed soy protein derived materials. The invention further relates to the use of these T2R receptors in assays for identifying ligands that modulate the activation of these taste receptors by specific bitter ligands present in hydrolyzed soy protein materials and derivatives thereof and related compounds. These compounds may be used as additives and/or removed from soy-based foods, beverages, cosmetics and medicinals in order to modify (block) T2R-associated bitter taste elicited by bitter ligands present in hydrolyzed soy protein materials.

  • Publication number: 20100161337
    Abstract: Disclosed herein are systems, computer-implemented methods, and computer-readable media for recognizing speech. The method includes receiving speech from a user, perceiving at least one speech dialect in the received speech, selecting at least one grammar from a plurality of optimized dialect grammars based on at least one score associated with the perceived speech dialect and the perceived at least one speech dialect, and recognizing the received speech with the selected at least one grammar. Selecting at least one grammar can be further based on a user profile. Multiple grammars can be blended. Predefined parameters can include pronunciation differences, vocabulary, and sentence structure. Optimized dialect grammars can be domain specific. The method can further include recognizing initial received speech with a generic grammar until an optimized dialect grammar is selected. Selecting at least one grammar from a plurality of optimized dialect grammars can be based on a certainty threshold.
