The computing device obtains an original sound from the at least one mobile terminal and converts the original sound into a digitized time-frequency map, performs compression segmentation on the time-frequency map to obtain a sound image corresponding to the time-frequency map, and uses an image recognition method to recognize the sound image, obtain an enhanced sound image, and search a preset database for sound information corresponding to the enhanced sound image. | 2020-09-17 |
20200294527 | Diagnostic techniques based on speech models - A speech model constructed from reference speech samples, which were produced by a subject at a first time while a physiological state of the subject was known, is obtained. The model includes (i) acoustic states exhibited in the reference speech samples and associated with respective local distance functions, and (ii) allowed transitions between the acoustic states. A test speech sample that was produced by the subject at a second time, while the physiological state of the subject was unknown, is received. Test-sample feature vectors that quantify acoustic features of different respective portions of the test speech sample are computed. Based on the local distance functions and the allowed transitions, the test speech sample is mapped to a minimum-distance sequence of the acoustic states. In response thereto, an output indicating the physiological state of the subject at the second time is generated. Other embodiments are also described. | 2020-09-17 |
20200294528 | SYSTEM AND METHOD FOR FRUSTRATION DETECTION - A computer based system and method for automatically detecting frustration in an interaction, may include: identifying in the interaction using a set of linguistic rules, natural language patterns related to frustration, wherein the linguistic rules further define weights associated with the natural language patterns and rule metadata; reviewing the rule metadata associated with the identified natural language patterns to identify override attributes, wherein if the rule metadata does not include override attributes, then a frustration level in the interaction is determined based on the identified natural language patterns and weights associated with the identified natural language patterns; and if the rule metadata includes override attributes than the frustration level is determined based on the identified override attributes. | 2020-09-17 |
20200294529 | METHOD FOR IMPROVING A STATE OF A RIDER THROUGH OPTIMIZATION OF OPERATION OF A VEHICLE - A method for improving a state of a rider through optimization of operation of a vehicle includes capturing vehicle operation-related data with at least one Internet-of-things device, and analyzing the captured data with a first neural network that determines a state of the vehicle based at least in part on a portion of the captured vehicle operation-related data. The method further includes receiving data descriptive of a state of a rider occupying the operating vehicle, and using a neural network to determine at least one vehicle operating parameter that affects a state of a rider occupying the operating vehicle. The method still further includes using an artificial intelligence-based system to optimize the at least one vehicle operating parameter so that a result of the optimizing includes an improvement in the state of the rider. | 2020-09-17 |
20200294530 | ARTIFICIAL INTELLIGENCE SYSTEM FOR VEHICLE IN-SEAT ADVERTISING - An artificial intelligence system for vehicle in-seat advertising includes a first portion of the artificial intelligence system that determines an operating state of the vehicle by processing inputs relating to at least one parameter of the vehicle. A second portion of the artificial intelligence system determines a state of a rider of the vehicle by processing inputs relating to at least one parameter of the rider. A third portion of the artificial intelligence system determines at least one of a price, classification, content and location of an advertisement to be delivered within an interface of the vehicle to a rider in a seat in the vehicle based on the vehicle state and the rider state. | 2020-09-17 |
