20140324591 | SELECTIVELY AUTHENTICATING A GROUP OF DEVICES AS BEING IN A SHARED ENVIRONMENT BASED ON LOCALLY CAPTURED AMBIENT SOUND - In an embodiment, two or more local wireless peer-to-peer connected user equipments (UEs) capture local ambient sound, and report information associated with the captured local ambient sound to an authentication device. The authentication device compares the reported information to determine a degree of environmental similarity for the UEs, and selectively authenticates the UEs as being in a shared environment based on the determined degree of environmental similarity. A given UE among the two or more UEs selects a target UE for performing a given action based on whether the authentication device authenticates the UEs as being in the shared environment. | 10-30-2014 |
20140334645 | METHOD AND APPARATUS FOR CONTROLLING VOICE ACTIVATION - A method for controlling voice activation by a target keyword in a mobile device is disclosed.

When the input sound stream indicates speech, the voice activation unit is activated to detect the target keyword and at least one sound feature is extracted from the input sound stream. Further, the method includes deactivating the voice activation unit when the at least one sound feature indicates a non-target keyword. | 11-13-2014 |
20140337030 | ADAPTIVE AUDIO FRAME PROCESSING FOR KEYWORD DETECTION - A method of detecting a target keyword from an input sound for activating a function in a mobile device is disclosed. In this method, a first plurality of sound features is received in a buffer, and a second plurality of sound features is received in the buffer. While receiving each of the second plurality of sound features in the buffer, a first number of the sound features are processed from the buffer. The first number of the sound features includes two or more sound features. Further, the method may include determining a keyword score for each of the processed sound features and detecting the input sound as the target keyword if at least one of the keyword scores is greater than a threshold score. | 11-13-2014 |
20140337031 | METHOD AND APPARATUS FOR DETECTING A TARGET KEYWORD - A method of detecting a target keyword for activating a function in an electronic device is disclosed. The method includes receiving an input sound starting from one of the plurality of portions of the target keyword. The input sound may be periodically received based on a duty cycle. The method extracts a plurality of sound features from the input sound, and obtains state information on a plurality of states associated with the portions of the target keyword. Based on the extracted sound features and the state information, the input sound may be detected as the target keyword. The plurality of states includes a predetermined number of entry states indicative of a predetermined number of the plurality of portions. | 11-13-2014 |
20150066925 | Method and Apparatus for Classifying Data Items Based on Sound Tags - A method for grouping data items in a mobile device is disclosed. In this method, a plurality of data items and a sound tag associated with each of the plurality of data items are stored, and the sound tag includes a sound feature extracted from an input sound indicative of an environmental context for the data item. Further, the method may include generating a new data item, receiving an environmental sound, generating a sound tag associated with the new data item by extracting a sound feature from the environmental sound, and grouping the new data item with at least one of the plurality of data items based on the sound tags associated with the new data item and the plurality of data items. | 03-05-2015 |
20150078667 | METHOD AND APPARATUS FOR SELECTIVELY PROVIDING INFORMATION ON OBJECTS IN A CAPTURED IMAGE - A method for providing object information for a scene in a wearable computer is disclosed. In this method, an image of the scene is captured. Further, the method includes determining a current location of the wearable computer and a view direction of an image sensor of the wearable computer and extracting at least one feature from the image indicative of at least one object. Based on the current location, the view direction, and the at least one feature, information on the at least one object is determined Then, the determined information is output. | 03-19-2015 |
20150081295 | METHOD AND APPARATUS FOR CONTROLLING ACCESS TO APPLICATIONS - According to an aspect of the present disclosure, a method for controlling access to a plurality of applications in an electronic device is disclosed. The method includes receiving a voice command from a speaker for accessing a target application among the plurality of applications, and verifying whether the voice command is indicative of a user authorized to access the applications based on a speaker model of the authorized user. In this method, each application is associated with a security level having a threshold value. The method further includes updating the speaker model with the voice command if the voice command is verified to be indicative of the user, and adjusting at least one of the threshold values based on the updated speaker model. | 03-19-2015 |
20150081296 | METHOD AND APPARATUS FOR ADJUSTING DETECTION THRESHOLD FOR ACTIVATING VOICE ASSISTANT FUNCTION - A method for activating a voice assistant function in a mobile device is disclosed. The method includes receiving an input sound stream by a sound sensor and determining a context of the mobile device. The method may determine the context based on the input sound stream. For determining the context, the method may also obtain data indicative of the context of the mobile device from at least one of an acceleration sensor, a location sensor, an illumination sensor, a proximity sensor, a clock unit, and a calendar unit in the mobile device. In this method, a threshold for activating the voice assistant function is adjusted based on the context. The method detects a target keyword from the input sound stream based on the adjusted threshold. If the target keyword is detected, the method activates the voice assistant function. | 03-19-2015 |
