Abstract: A synchronization process between captioning data and/or corresponding metatags and the associated media file parses the media file, correlates the caption information and/or metatags with segments of the media file, and provides a capability for textual search and selection of particular segments. A time-synchronized version of the captions is created that is synchronized to the moment that the speech is uttered in the recorded media. The caption data is leveraged to enable search engines to index not merely the title of a video, but the entirety of what was said during the video as well as any associated metatags relating to contents of the video. Further, because the entire media file is indexed, a search can request a particular scene or occurrence within the event recorded by the media file, and the exact moment within the media relevant to the search can be accessed and played for the requester.

Abstract: The example embodiment of the present invention provides an acoustic model adaptation method for enhancing recognition performance for a non-native speaker's speech. In order to adapt acoustic models, first, pronunciation variations are examined by analyzing a non-native speaker's speech. Thereafter, based on variation pronunciation of a non-native speaker's speech, acoustic models are adapted in a state-tying step during a training process of acoustic models. When the present invention for adapting acoustic models and a conventional acoustic model adaptation scheme are combined, more-enhanced recognition performance can be obtained. The example embodiment of the present invention enhances recognition performance for a non-native speaker's speech while reducing the degradation of recognition performance for a native speaker's speech.

Abstract: Systems and methods are described for speech systems that utilize an interaction manager to manage interactions—also known as dialogues—from one or more applications. The interactions are managed properly even if multiple applications use different grammars. The interaction manager maintains an interaction list. An application wishing to utilize the speech system submits one or more interactions to the interaction manager. Interactions are normally processed in the order in which they are received. An exception to this rule is an interaction that is configured by an application to be processed immediately, which causes the interaction manager to place the interaction at the front of the interaction list of interactions. If an application has designated an interaction to interrupt a currently processing interaction, then the newly submitted application will interrupt any interaction currently being processed and, therefore, it will be processed immediately.
