Amazon patents voice tech that learns your personal names
This patent describes a method for automatic speech recognition that mixes your voice input with data from your user profile. By using a machine learning model, the system focuses on audio parts that match specific words you have saved, such as contact names or device names, to improve accuracy.
In the filing’s own words
Techniques for performing automatic speech recognition (ASR) are described. In some embodiments, an ASR component integrates contextual information from user profile data into audio encoding data to predict a token(s) corresponding to a spoken input. The user profile data may include personalized words, such as, contact names, device names, etc. The ASR component determines word embedding data using the personalized words. The ASR component is configured to apply attention to audio frames that are relevant to the personalized words based on processing the audio encoding data and the word embedding data.
What exactly they claim (claim 1)
1. A computer-implemented method comprising: receiving input data corresponding to a natural language input; determining user profile data corresponding to the input data; determining first encoding data using at least a first word included in the user profile data; determining second encoding data corresponding to at least a first portion of the input data; processing the first encoding data and the second encoding data to determine model input data; processing the model input data using a machine learning model to determine at least a first token; and processing the first token to determine output data representing a response to the natural language input, wherein the response is based at least in part on the user profile data.
