An example method includes receiving, from one or more external electronic devices, a plurality of speaker profiles for a plurality of users; receiving a natural language speech input; determining, based on comparing the natural language speech input to the plurality of speaker profiles: a first likelihood that the natural language speech input corresponds to a first user of the plurality of users; and a second likelihood that the natural language speech input corresponds to a second user of the plurality of users; determining whether the first likelihood and the second likelihood are within a first threshold; and in accordance with determining that the first likelihood and the second likelihood are not within the first threshold: providing a response to the natural language speech input, the response being personalized for the first user. | 2021-01-14 |
20210012777 | CONTEXT ACQUIRING METHOD AND DEVICE BASED ON VOICE INTERACTION - Embodiments of the present disclosure provide a context acquiring method based on voice interaction and a device, the method comprising: acquiring a scene image collected by an image collection device at a voice start point of a current conversation, and extracting a face feature of each user in the scene image; if it is determined that there is a second face feature matching a first face feature according to the face feature of each user and a face database, acquiring a first user identifier corresponding to the second face feature from the face database; if it is determined that a stored conversation corresponding to the first user identifier is stored in a voice database, determine a context of a voice interaction according to the current conversation and the stored conversation, and after the voice end point of the current conversation is obtained, storing the current conversation into the voice database. | 2021-01-14 |
20210012778 | INFORMATION PROCESSING DEVICE AND INFORMATION PROCESSING SYSTEM - An information processing device according to the present disclosure includes an information extractor and a judging unit. The information extractor extracts specific information regarding a user. The specific information is contained in contents of an utterance of the user. The extraction is made on a basis of the contents of the utterance of the user at a time of holding a dialog with any one agent out of a plurality of virtual agents. The judging unit judges which agent, out of the plurality of agents, use permission to use the extracted specific information is given to. The judgment is made on the basis of the specific information extracted by the information extractor, and adds a result of the judgment to the specific information as use permission information. | 2021-01-14 |
20210012779 | Multi-User Personalization at a Voice Interface Device - A method at an electronic device with one or more microphones and a speaker includes receiving a first voice input; comparing the first voice input to one or more voice models; based on the comparing, determining whether the first voice input corresponds to any of a plurality of occupants, and according to the determination, authenticating an occupant and presenting a response, or restricting functionality of the electronic device. | 2021-01-14 |
20210012780 | AUDIO INPUT FILTERING BASED ON USER VERIFICATION - One embodiment provides a method, including: detecting, using an audio capture device associated with an information handling device, audible input; determining, using a processor, whether the audible input is associated with an authorized user; and performing, responsive to determining that the audible input is not associated with the authorized user, a silencing action associated with the audio capture device. Other aspects are described and claimed. | 2021-01-14 |
20210012781 | DECODING OF AUDIO SCENES - Exemplary embodiments provide encoding and decoding methods, and associated encoders and decoders, for encoding and decoding of an audio scene which is represented by one or more audio signals. The encoder generates a bit stream which comprises downmix signals and side information which includes individual matrix elements of a reconstruction matrix which enables reconstruction of the one or more audio signals in the decoder. | 2021-01-14 |
20210012782 | Processing of a monophonic signal in a 3D audio decoder, delivering a binaural content - A method for processing a monophonic signal in a 3D audio decoder, including processing binauralizing decoded signals intended to be delivered spatially by a headset. The method is such that, on detection, in a datastream representative of the monophonic signal, of an indication of non-binauralization processing, which indication is associated with spatial delivery position information, the decoded monophonic signal is directed to a stereophonic rendering engine, which takes into account the position information to construct two delivery channels that are directly processed via a direct mixing that sums these two channels with a binauralized signal output from the binauralization processing, in order to be delivered via the headset. A decoder device that implements the processing method is also provided. | 2021-01-14 |
