Publication number: 20230395068Abstract: The present invention provides a noise modeling method to improve the speech recognition quality to help the recognition system perform better in real-life environments. With this method, we not only add noise to the training audio signal to simulate different environments, but we also add noise labels to the speech transcripts. Since then, the recognition model will perform better in different environments and increase the accuracy of the recognition model.Type: ApplicationFiled: April 7, 2023Publication date: December 7, 2023Applicant: VIETTEL GROUPInventors: Van Hai Do, Nhat Minh Le, Tung Lam Nguyen, Tien Thanh Nguyen, Dang Linh Le, Dinh Son Dang, Thi Ngoc Anh Nguyen, Minh Khang Pham, Bao Thang Ta, Quang Tien Duong, Ngoc Dung Nguyen, Manh Quan Tran, Manh Quy Nguyen

Publication number: 20230077863Abstract: Provided are methods for search algorithms and safety verification for compliant domain volumes. The present techniques include identifying a parameterized scenario space and objective function. A boundary between compliant scenarios and non-compliant scenarios for metrics in the parameterized scenario space is determined. A total boundary of a domain volume corresponding to the parameterized scenario space is identified based on the boundaries between the compliant scenarios and non-compliant scenarios for each metric in the parameterized scenario space.Type: ApplicationFiled: September 9, 2022Publication date: March 16, 2023Inventors: Scott D. Pendleton, Aleksandar Petrov Petrov, Carter Tung Yung Fang, Minh Khang Pham, James Guo Ming Fu, You Hong Eng

Publication number: 20230008613Abstract: The present invention provides a method for speech separation and recognition. The present invention overcomes the disadvantages of the existing techniques by providing automatic speech recognition and separation that helps managers see what their service agents and customers are saying. From there, quickly and objectively knowing the wishes and concerns of customers as well as whether their service agents can give accurate and correct advice. In addition, the system is constantly updated based on the semi-supervised training mechanism, which means that the system can self-learn from actual data during operation, thereby helping to improve the system's accuracy.Type: ApplicationFiled: June 30, 2022Publication date: January 12, 2023Applicant: VIETTEL GROUPInventors: Van Hai Do, Nhat Minh Le, Tung Lam Nguyen, Quang Trung Le, Tien Thanh Nguyen, Dang Linh Le, Dinh Son Dang, Thi Ngoc Anh Nguyen, Minh Khang Pham, Ngoc Dung Nguyen, Manh Quan Tran, Manh Quy Nguyen

Publication number: 20200301916Abstract: A data analysis system allows users to interact with distributed data structures stored in-memory using natural language queries. The data analysis system receives a prefix of a natural language query from the user. The data analysis system provides suggestions of terms to the user for adding to the prefix. Accordingly, the data analysis system iteratively receives longer and longer prefixes of the natural language queries until a complete natural language query is received. The data analysis system stores natural language query templates that represent natural language queries associated a particular intent. For example, a natural language query template may represent queries that compare two columns of a dataset. The data analysis system compares an input prefix of natural language with the natural language query templates to determine the suggestions. The data analysis system receives user defined metrics or attributes that can be used in the natural language queries.Type: ApplicationFiled: June 10, 2020Publication date: September 24, 2020Inventors: Christopher Nguyen, Anh H. Trinh, Khang Pham

Patent number: 8967196Abstract: A valve assembly may include a valve disposed in a flow path and an actuator disposed above the valve. The actuator may be configured to actuate the valve to move between an open position and a closed position. The valve may also include a rocking member disposed above the actuator and configured to move with the valve. The valve may also include a pair of first and second position sensors disposed above and parallel to the actuator. The pair of first and second position sensors may be configured to detect a position of the rocking member.
