Amazon patents voice tech that uses other devices to guess who is speaking
This patent describes a system that improves voice command accuracy by using data from other nearby devices to identify the likely speaker. It combines information from the main device with context from a second device to narrow down who is talking, which helps the computer understand the request better.
In the filing’s own words
This disclosure proposes systems and methods for processing natural language inputs using data associated with multiple language recognition contexts (LRC). A system using multiple LRCs can receive input data from a device, identify a first identifier associated with the device, and further identify second identifiers associated with the first identifier and representing candidate users of the device. The system can access language processing data used for natural language processing for the LRCs corresponding to each of the first and second identifiers, and process the input data using the language processing data at one or more stages of automatic speech recognition, natural language understanding, entity resolution, and/or command execution. User recognition can reduce the number of candidate users, and thus the amount of data used to process the input data. Dynamic arbitration can select from between competing hypotheses representing the first identifier and a second identifier, respectively.
What exactly they claim (claim 1)
1. A computer-implemented method, comprising: receiving, by a language processing component from a first device, input data corresponding to a natural language input; receiving, from a second device, first context data corresponding to the input data, the first context data comprising a user identifier corresponding to a first possible user of the first device; and performing, by the language processing component based on the first context data and the user identifier, first language processing on the input data to generate output data.
