One or more characteristics of input signals may be used to select a particular selection region. A particular value combination of the set of weighting factors may be chosen to attenuate or amplify the input signals to generate one or more output signals. | 2015-10-01 |
20150279389 | Voice Activated Features on Multi-Level Voice Menu - Methods, apparatus, and computer-readable media are described herein related to a user interface (UI) that can be implemented on a head-mountable device (HMD). The UI can include a voice-navigable UI. The voice-navigable UI can include a voice navigable menu that includes one or more menu items comprising an original menu item and an added command menu item. The original menu item can be associated with one or more original commands, and the added menu item can be associated with one or more added commands, including a first added command. The interface can also present a first visible menu that includes at least a portion of the voice navigable menu. Responsive to a first utterance comprising the first added command, the interface can invoke the first added command. In some embodiments, the interface can display a second visible menu, wherein the first added command can be displayed above other menu items. | 2015-10-01 |
20150279390 | SYSTEM AND METHOD FOR SUMMARIZING A MULTIMEDIA CONTENT ITEM - A multimedia content item is summarized based on its audio track and a desired compression budget. The audio track is extracted and processed by an automatic speech recognizer to obtain a time-aligned text transcript. The text-transcript is partitioned into a plurality of segment sequences. An informativeness score based on a salience score and a diversity score is computed for each of the segments. A coherence score is also computed for the segments in the plurality of sequences. A subsequence of one of the segment sequences that optimizes for informativeness and coherence is selected for generating a new content item summarizing the multimedia content item. | 2015-10-01 |
20150279391 | DISSATISFYING CONVERSATION DETERMINATION DEVICE AND DISSATISFYING CONVERSATION DETERMINATION METHOD - This dissatisfying conversation determination device include: a data acquisition unit that acquires a plurality of word data, and a plurality of phonation time data by target conversation participants; an extraction unit that extracts a plurality of specific word data configuring polite expression and impolite expression from the plurality of word data; a change detection unit that detects a point of change from polite expression to impolite expression by the target conversation participants based on the plurality of specific word data and the plurality of phonation time data; and a dissatisfaction determination unit that determines whether the target conversation is a dissatisfying conversation for the target conversation participants based on the result of the point of change detected by the change detection unit. | 2015-10-01 |
