Patent number: 11158314Abstract: A voice control device includes a user database, a first image capturing module, a voice command module and a management module. The user database stores first user identification data of a first user account. The first image capturing module captures an environmental image. The voice command module is enabled to receive a voice command for controlling the voice control device. The management module is used to detect whether at least one facial image exists in the environmental image, and detect whether the facial image matches with the first user identification data, and when the facial image matches with the first user identification data, the management module logs in the first user account and enables the voice command module.Type: GrantFiled: April 15, 2019Date of Patent: October 26, 2021Assignee: PEGATRON CORPORATIONInventors: Cheng-Yu Kao, Nien-Chih Wang, Yu-Hung Tseng, Yueh-Fei Chang, Chih-Lun Wang

Patent number: 10990839Abstract: An anti-counterfeit method for assisting in face recognition includes the following steps: capturing a dynamic image of an object; filtering a plurality of time-varying signals from the dynamic image to obtain a plurality of filter signals; and comparing the filter signals and preset biological information that corresponds to the object, to output a determining result. When the dynamic image of the object is captured, according to this method, at least one region is interest is set in the dynamic image, and each time-varying signal corresponds to a time-varying gray-scale value of at least one pixel of the dynamic image in the region of interest. An anti-counterfeit system is also provided.Type: GrantFiled: January 23, 2019Date of Patent: April 27, 2021Assignee: PEGATRON CORPORATIONInventors: Wei-Hua Hao, Nien-Chih Wang

Patent number: 7606710Abstract: A method for text-to-pronunciation conversion includes a process for searching grapheme-phoneme segments and a three-stage process of text-to-pronunciation conversion. This method looks for a sequence of grapheme-phoneme pairs, which is referred to as a chunk, via a trained pronouncing dictionary, performs grapheme segmentation, chunk marking and a decision process on an input text, and determines a pronouncing sequence for the text. With the chunk marking, the method greatly reduces the search space on the associated phoneme graph, and thereby efficiently enhances the search speed for the candidate chunk sequences. The method keeps a high word-accuracy as well as saves computing time.Type: GrantFiled: December 21, 2005Date of Patent: October 20, 2009Assignee: Industrial Technology Research InstituteInventors: Nien-Chih Wang, Ching-Hsieh Lee
