US10951706B2 High-throughput algorithm for multiversion concurrency control with globally synchronized time
Throughput is preserved in a distributed system while maintaining concurrency by pushing a commit wait period to client commit paths and to future readers. As opposed to servers performing commit waits, the servers assign timestamps, which are used to ensure that causality is preserved. When a server executes a transaction that writes data to a distributed database, the server acquires a user-level lock, and assigns the transaction a timestamp equal to a current time plus an interval corresponding to bounds of uncertainty of clocks in the distributed system. After assigning the timestamp, the server releases the user-level lock. Any client devices, before performing a read of the written data, must wait until the assigned timestamp is in the past.

US10951669B2 Reverse call forking
A technique for merging conference session dialogs allows presenting content and media streams from a non-Skype endpoint to a Skype multipoint control unit (MCU), so that they present a single caller in a conference with both media and content. A signaling adapter intercepts session dialogs and merges or other modifies. When adding the non-Skype endpoint, requests from a content server are dropped while requests from the MCU handling non-Skype media streams are forwarded to the Skype MCU. Responses to the request from the MCU are also forwarded to the content server. When creating subscription dialogs, requests from the content server are modified to appear as if they came from the MCU, while responses go back to the proper requester. Conference notifications are forked to go to both the content server and the MCU. Because Skype uses separate media and content dialogs, merging of audio/video and content dialogs may be omitted. By merging dialogs, user experience is improved.

The method includes: acquiring voice data, and determining whether the voice data includes a wake-up word, when positions of the Bluetooth speaker base and a Bluetooth speaker satisfy a preset condition; controlling the Bluetooth speaker base to enter a wake-up recognition state, and compressing the voice data based on a compression ratio, when the voice data includes the wake word; and sending the voice data compressed to a mobile terminal through a first profile, to cause the mobile terminal to decompress the voice data received, send the voice data decompressed to a server for voice recognition to obtain audio data, and send the audio data to the Bluetooth speaker for playback through a second profile.
US10950230B2 Information processing device and information processing method
Included are a speech recognition result obtainer that obtains a speech recognition result, which is text data obtained by speech recognition processing, a priority obtainer that obtains priority corresponding to each of a plurality of tasks that are each identified by a plurality of dialog processing based on the speech recognition result; and a dialog processing controller that causes a plurality of devices to perform the distributed execution of the plurality of dialog processing mutually different from each other. The dialog processing controller provides, based on the priority, control information in accordance with a task identified by the distributed execution to an executer that operates based on the control information.
US10950228B1 Interactive voice controlled entertainment
Methods and systems for receiving shouted-out user responses to broadcast entertainment content, and for determining the responsiveness of those responses in relation to the broadcast content. In particular, entertainment broadcasts can be accompanied by mark-up data that represents various events within a given broadcast, which can be compared to the shouted-out responses to determine their accuracy. For example, if a game show was broadcast and an individual started shouting out answers during the broadcast, embodiments disclosed herein could utilize a voice-controlled electronic device that captures the shouted-out answers and passes them on to a language processing system that determines whether they are correct by comparing the answers to the mark-up data. The voice-controlled electronic device can also “listen” to background sounds to capture the broadcast of the entertainment content, and send that content to the language processing system, which can use that captured data to synchronize the actual broadcast with the analysis of the shouted-out answers to provide individuals with an immersive entertainment experience.
US10950226B2 System and method for activation of voice interactive services based on user state
The present invention provides a system for activating personal assistance services. The system includes an audio data collector adapted to collect a sample of speech, a processing module, and a service activator couple to an output device. The processing module further includes an audio feature extractor that extracts a plurality of acoustic features from the sample of speech, and a classification unit that classifies a status of a user from the plurality of acoustic features. The Service activator activates a personal assistance service according to the status of the user classified by the classification unit.
US10950225B2 Acoustic model learning apparatus, method of the same and program
An acoustic model learning apparatus includes a first output probability distribution calculating part that calculates a first output probability distribution including a distribution of output probabilities of respective units of an output layer using a feature amount obtained from an acoustic signal for learning and a learned first acoustic model including a neural network, and the first output probability distribution calculating part obtains the first output probability distribution using a smoothing parameter made up of a real value greater than 0 as input so that the first output probability distribution approaches a uniform distribution as the smoothing parameter is greater, and calculates the first output probability distribution by obtaining logits of respective units of an output layer using the feature amount obtained from the acoustic signal for learning and the first acoustic model and setting a value of the smoothing parameter greater in the case where an output unit number with the greatest logit value is different from a correct unit number than in the case where the output unit number with the greatest logit value matches the correct unit number.
US10950218B2 Drive system and electric apparatus provided therewith
A drive system includes an actuator including an electric motor, a microphone, and a sound generator emitting a sound in response to a signal derived from sound caught by the microphone. The microphone is attached to the actuator. This drive system makes it easy to establish an optimal positional relationship between the microphone and the noise source in the actuator, thereby properly reducing noise arising from the actuator.
