Abstract

Described are techniques for predicting when data associated with a user input is likely to be selected for deletion. The system may use a trained model to assist with such predictions. The trained model can be configured based on deletions associated with a user profile. An example process can including receiving user input data corresponding to the user profile, and processing the user input data to determine a user command. Based on characteristic data of the user command, the trained model can be used to determine that data corresponding to the user command is likely to be selected for deletion. The trained model can be iteratively updated based on additional user commands, including previously received user commands to delete user input data.

Claims20

Dependent claims

A computer-implemented method comprising:

receiving first audio data corresponding to a first user profile, the first audio data representing a first utterance;
performing speech processing on the first audio data to determine a first user command;
executing the first user command;
storing first data related to processing of the first utterance;
receiving a request to delete the first data;
causing the first data to be deleted;
determine first characteristic data corresponding to the first utterance;
using the first characteristic data to configure at least one trained model;
storing association data with respect to the first user profile, the association data associating the first user profile with the at least one trained model;
receiving second audio data corresponding to the first user profile, the second audio data representing a second utterance;
determining second data related to processing of the second utterance;
determining second characteristic data corresponding to the second utterance;
and
processing the second characteristic data using the at least one trained model to determine the second data is to be selected for deletion.

11 more elements

A system, comprising:

at least one processor;
and
at least one memory comprising instructions that, when executed by the at least one processor, cause the system to:
receive first input data corresponding to a first user input, the first input data corresponding to a first user profile;
process the first input data to determine a first user command corresponding to the first input data;
store the first input data in a storage medium;
cause the first user command to be executed;
determine first characteristic data corresponding to the first input data;
determine a trained model associated with the first user profile;
and
process the first characteristic data using the trained model to determine that the first input data stored in the storage medium is to be selected for deletion from the storage medium.
