摘要： A speech recognition apparatus includes a a low-order parameter analyzation section for deriving low-order parameter time series of an input speech, a start and end point detection section for detecting the start and end points of the input speech by use of the parameter time series derived by the low-order parameter analyzation section, a high-order parameter analyzation section for deriving high order parameters at preset sampling points from the input speech of a range corresponding to the start and end points detected by the start and end point detection section, a pattern matching section for matching feature parameters corresponding to the parameters derived by the high-order parameter analyzation section with standard parameters previously registered and deriving similarities between the matched parameters, and a recognition result outputting section for outputting the recognition result for the input speech according to the similarities derived by the pattern matching section.

摘要： A speech dialogue system capable of realizing natural and smooth dialogue between the system and a human user, and easy maneuverability of the system. In the system, a semantic content of input speech from a user is understood and a semantic content determination of a response output is made according to the understood semantic content of the input speech. Then, a speech response and a visual response according to the determined response output are generated and outputted to the user. The dialogue between the system and the user is managed by controlling transitions between user states during which the input speech is to be entered and system states during which the system response is to be outputted. The understanding of a semantic content of input speech from a user is made by detecting keywords in the input speech, with the keywords to be detected in the input speech limited in advance, according to a state of a dialogue between the user and the system.
摘要翻译：一种语音对话系统，能够实现系统和人类用户之间的自然而平稳的对话，并且系统的易操作性。在系统中，理解来自用户的输入语音的语义内容，并且根据输入语音的理解语义内容进行响应输出的语义内容确定。然后，产生根据所确定的响应输出的语音响应和视觉响应并向用户输出。通过控制要输入输入语音的用户状态之间的转换以及要输出系统响应的系统状态来管理系统和用户之间的对话。根据用户和系统之间的对话状态，通过检测输入语音中的关键字，使输入语音中要检测的关键字被预先限制，从而进行对用户输入语音的语义内容的理解。
