Abstract:
A device includes a memory, a receiver, a processor, and a display. The memory is configured to store a speaker model. The receiver is configured to receive an input audio signal. The processor is configured to determine a first confidence level associated with a first portion of the input audio signal based on the speaker model. The processor is also configured to determine a second confidence level associated with a second portion of the input audio signal based on the speaker model. The display is configured to present a graphical user interface associated with the first confidence level or associated with the second confidence level.
Abstract:
A method and apparatus for performing a function in a mobile device are disclosed. A media sound from a sound output device external to the mobile device is captured and a sound feature is extracted from the captured media sound. A function to be performed in the mobile device is determined by identifying at least one reference sound feature in a set of reference sound features based on the extracted sound feature, each reference sound feature in the set of reference sound features being associated with at least one of a plurality of media sounds and at least one of a plurality of functions. Further, the determined function is performed in the mobile device.
Abstract:
A method includes receiving an alarm sound including information related to an emergency event. The method also includes transmitting, to a server, identification information of the mobile device and the information. The method further includes receiving, from the server, an instruction for responding to the emergency event. The method further includes outputting the instruction.
Abstract:
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.
Abstract:
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.
Abstract:
A method for communicating messages by a mobile device via a sound medium is disclosed. The mobile device receives input sounds from at least one mobile device via the sound medium. From the input sounds, an input sound signal carrying a first message encoded with a first key is detected. The mobile device decodes the first message based on a matching key. An output sound signal carrying a second message encoded with a second key is generated. Further, the mobile device transmits an output sound corresponding to the output sound signal via the sound medium.
Abstract:
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.
Abstract:
A method for controlling voice activation by a target keyword in a mobile device is disclosed. The method includes receiving an input sound stream. 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.
Abstract:
A method for verifying at least one sound sample to be used in generating a sound detection model in an electronic device includes receiving a first sound sample; extracting a first acoustic feature from the first sound sample; receiving a second sound sample; extracting a second acoustic feature from the second sound sample; and determining whether the second acoustic feature is similar to the first acoustic feature.
Abstract:
A method, which is performed in a first electronic device, for authorizing access to a second electronic device is disclosed. The method may include establishing communication between the first electronic device and the second electronic device. The method may also obtain data indicative of a motion of at least one of the first and second electronic devices in response to a movement of the at least one of the first and second electronic devices. Based on the data, a control signal authorizing access to the second electronic device is generated, and transmitted to the second electronic device.
