Execution speed of a thread is dynamically restored while reducing influence on processing accuracy of the whole system. A thread synchronization device (10) achieves synchronization among N threads (1-1, . . . , 1-N) to perform parallel processing by dividing time-series data into a plurality of pieces of data. Environment variables which achieve a trade-off between processing accuracy and execution speed are individually set at the threads (1-1, . . . , 1-N). An execution speed calculation unit (2) calculates execution speed of each of the threads. An environment variable update unit (3) updates the environment variables in accordance with the execution speed of the threads.

A refrigerator comprises a storage compartment configured to store food, a temperature detector configured to detect an internal temperature of the storage compartment, a cooler configured to supply cool air to the storage compartment, a microphone configured to receive a speech, a display configured to display information, at least one processor configured to be electrically connected to the temperature detector, the microphone, and the display; and a memory configured to be electrically connected to the at least one processor. The memory stores at least one instructions configured to, when a first speech including a food name is recognized via the microphone, allow the processor to display a food list, which comprises food information corresponding to the food name and an identification mark identifying the food information, on the display, and configured to, when a second speech referring to the identification mark is recognized via the microphone, allow the processor to display food purchase information corresponding to the identification mark, on the display.

A voice processing system includes: a first acquisition processor that acquires voice data corrected by a microphone installed in a microphone-speaker device; a second acquisition processor that acquires authentication information of a wearer who wears the microphone-speaker device, the authentication information being acquired by an authentication information acquirer installed in the microphone-speaker device; and a control processor that executes predetermined processing related to the voice data, which is acquired by the first acquisition processor, on the basis of the authentication information acquired by the second acquisition processor.

A system and corresponding method are provided for generating responses for a dialogue between a user and a computer. The system includes a memory storing information for a dialogue history and a knowledge base. An encoder may receive a new utterance from the user and generate a global memory pointer used for filtering the knowledge base information in the memory. A decoder may generate at least one local memory pointer and a sketch response for the new utterance. The sketch response includes at least one sketch tag to be replaced by knowledge base information from the memory. The system generates the dialogue computer response using the local memory pointer to select a word from the filtered knowledge base information to replace the at least one sketch tag in the sketch response.

Provided is technology for assessing whether uttered speech detected from input speech is speech suited to a prescribed purpose. A method comprises detecting, from input speech including speech uttered by a speaker and noise, the uttered speech corresponding to the speech uttered by the speaker, extracting an acoustic feature of the uttered speech, generating, from the uttered speech, a speech recognition result set with a recognition score, generating, from the speech recognition result set with the recognition score, a speech recognition result word vector expression set and a speech recognition result part-of-speech vector expression set, generating a target utterance estimation model, providing, using the target utterance estimation model, a probability of the uttered speech being suited to the prescribed purpose, and outputting the uttered speech and the speech recognition result set with the recognition score, the the uttered speech suitable to the prescribed purpose.

Disclosed are a voice recognition system and a display device using the same. The disclosed voice recognition system includes a plate structure, a vibration sensor, and a voice recognition device. The plate structure vibrates based on propagation of a voice wave generated from a user, and the vibration sensor is provided in contact with the plate structure to detect the vibration of the plate structure. The voice recognition device recognizes voice of the user by receiving a signal output from the vibration sensor.

An exemplary method for using a virtual assistant may include, at an electronic device configured to transmit and receive data, receiving a user request for a service from a virtual assistant; determining at least one task to perform in response to the user request; estimating at least one performance characteristic for completion of the at least one task with the electronic device, based on at least one heuristic; based on the estimating, determining whether to execute the at least one task at the electronic device; in accordance with a determination to execute the at least one task at the electronic device, causing the execution of the at least one task at the electronic device; in accordance with a determination to execute the at least one task outside the electronic device: generating executable code for carrying out the least one task; and transmitting the executable code from the electronic device.

Disclosed herein is a cooking system: a cooking apparatus configured to input and output a speech, transmit speech data corresponding to the speech, and cook food in a cooking chamber; a first server configured to perform communication with the cooking apparatus, when speech data is received from the cooking apparatus, perform speech recognition based on the received speech data, transmit response information to the speech recognition to the cooking apparatus, obtain a menu requested by the user based on the received speech data, and transmit a cooking time and a cooking temperature for the obtained menu to the cooking apparatus; and a second server configured to store information about at least one recipe for a plurality of menus, perform communication with the first server, and transmit the information about at least one recipe to the first server.
