Abstract: A method for conversational computing includes executing code embodying a conversational virtual machine, registering a plurality of input/output resources with a conversational kernel, providing an interface between a plurality of active applications and the conversational kernel processing input/output data, receiving input queries and input events of a multi-modal dialog across a plurality of user interface modalities of the plurality of active applications, generating output messages and output events of the multi-modal dialog in connection with the plurality of active applications, managing, by the conversational kernel, a context stack associated with the plurality of active applications and the multi-modal dialog to transform the input queries into application calls for the plurality of active applications and convert the output messages into speech, wherein the context stack accumulates a context of each of the plurality of active applications.

Abstract: A conversational computing system that provides a universal coordinated multi-modal conversational user interface (CUI) (10) across a plurality of conversationally aware applications (11) (i.e., applications that "speak" conversational protocols) and conventional applications (12). The conversationally aware applications (11) communicate with a conversational kernel (14) via conversational application APIs (13). The conversational kernel (14) controls the dialog across applications and devices (local and networked) on the basis of their registered conversational capabilities and requirements and provides a unified conversational user interface and conversational services and behaviors. The conversational computing system may be built on top of a conventional operating system and APIs (15) and conventional device hardware (16). The conversational kernel (14) handles all I/O processing and controls conversational engines (18). The conversational kernel (14) converts voice requests into queries and converts outputs and results into spoken messages using conversational engines (18) and conversational arguments (17). The conversational application API (13) conveys all the information for the conversational kernel (14) to transform queries into application calls and conversely convert output into speech, appropriately sorted before being provided to the user.

Abstract translation: 一种对话计算系统，其跨越多个会话感知应用（11）（即，“说”对话协议的应用“）和常规应用（12）提供通用协调多模式对话用户界面（CUI）（10）。 对话感知应用（11）通过对话应用API（13）与对话内核（14）通信。 对话内核（14）根据其注册的会话能力和要求，控制应用和设备（本地和网络）之间的对话，并提供统一的会话用户界面和对话服务和行为。 对话计算系统可以构建在常规操作系统和API（15）和常规设备硬件（16）之上。 对话内核（14）处理所有I / O处理和控制对话引擎（18）。 会话内核（14）将语音请求转换为查询，并将会话引擎（18）和会话参数（17）将输出和结果转换为口语消息。 对话应用程序API（13）传达对话内核（14）的所有信息，以将查询转换为应用程序调用，并相反地将输出转换为语音，在提供给用户之前进行适当排序。

Abstract: SPEECH RECOGNITION SYSTEM Apparatus and method for evaluating the likelihood of a word in a vocabulary of words wherein a total score is evaluated for each word, each total score being the result of combining at least two word scores generated by differing algorithms. In one embodiment, a detailed acoustic match word score is combined with an approximate acoustic match word score to provide a total word score for a subject word. In another embodiment, a polling word score is combined with an acoustic match word score to provide a total word score for a subject word. The acoustic models employed in the acoustic matching may correspond, alternatively, to phonetic elements or to fenemes. Fenemes represent labels generated by an acoustic processor in response to a spoken input. Apparatus and method for determining word scores according to approximate acoustic matching and for determining word scores according to a polling methodology are disclosed.

Abstract: The invention herein provides, in a speech recognition system which represents each vocabulary word or a portion thereof by at least one sequence of phones wherein each phone corresponds to a respective phone machine, each phone machine having associated therewith (a) at least one transition and (b) actual label output probabilities, each actual label probability representing the probability that a subject label is generated at a given transition in the phone machine, a method of performing an acoustic match between phones and a string of labels produced by an acoustic processor in response to a speech input, the method comprising the steps of: forming simplified phone machines which includes the step of replacing by a single specific value the actual label probabilities for a given label at all transitions at which the given label may be generated in a particular phone machine; and determining the probability of a phone generating the labels in the string based on the simplified phone machine corresponding thereto.
