Patent number: 11049501Abstract: One embodiment provides a method that includes obtaining a default language corpus. A second language corpus is obtained based on a second language preference. A first transcription of an utterance is received using the default language corpus and natural language processing (NLP). At least one problem word in the first transcription is determined based on an associated grammatical relevance to neighboring words in the first transcription. Upon determining that a first probability score is below a first threshold, an acoustic lookup is performed for an audible match for the problem word in the first transcription based on an associated acoustical relevance. Upon determining that a second probability score is below a second threshold, it is determined whether a match for the problem word exists in the secondary language corpus. Upon determining that the match exists in the secondary language corpus, a second transcription for the utterance is provided.Type: GrantFiled: September 25, 2018Date of Patent: June 29, 2021Assignee: International Business Machines CorporationInventors: Raphael Arar, Chris Kau, Robert J.

Patent number: 10984784Abstract: Techniques described herein relate to facilitating end-to-end multilingual communications with automated assistants. In various implementations, speech recognition output may be generated based on voice input in a first language. A first language intent may be identified based on the speech recognition output and fulfilled in order to generate a first natural language output candidate in the first language. At least part of the speech recognition output may be translated to a second language to generate an at least partial translation, which may then be used to identify a second language intent that is fulfilled to generate a second natural language output candidate in the second language. Scores may be determined for the first and second natural language output candidates, and based on the scores, a natural language output may be selected for presentation.Type: GrantFiled: April 16, 2018Date of Patent: April 20, 2021Assignee: GOOGLE LLCInventors: James Kuczmarski, Vibhor Jain, Amarnag Subramanya, Nimesh Ranjan, Melvin Jose Johnson Premkumar, Vladimir Vuskovic, Luna Dai, Daisuke Ikeda, Nihal Sandeep Balani, Jinna Lei, Mengmeng Niu

Patent number: 10984032Abstract: Generating, updating, and using a knowledge graph. Concepts in a knowledge graph can have relations to one another. These relations may be expressed as confidence values. A training data set may be split into two portions, with the first portion used to update confidence values for existing relations between concept pairs, using the knowledge graph. These confidence values can be used, together with the second portion used to update confidence values for known phrases that express known relations. These confidence values, in turn, can be used, together with the first portion, to increase the accuracy of the original confidence scores with respect to existing relations. The process may be iteratively employed, with each iteration increasing the accuracy of confidence scores.Type: GrantFiled: January 24, 2019Date of Patent: April 20, 2021Assignee: International Business Machines CorporationInventors: Tin Kam Ho, Luis A.
