Abstract: Techniques for performing feature computation are described. A system may gather and analyze event data to generate a timeline of the event data and corresponding feature data (e.g., statistical values representing the event data). The system can create a customized timeline that allows information to be sorted and aggregated in different timescales to improve speech processing and other functionality. For example, a feature computation system may calculate statistics and other information based on interactions with a speech processing system. These statistics provide information about previous interactions that may be leveraged to interpret future voice commands.

Abstract: Devices and techniques are generally described for pre-caching of speech processing feature data. In various examples, first data indicating source data is received from a first speech processing component. The source data may be used to generate first feature data. In various examples, a first request to process first input data is received. A second speech processing component may generate the source data during processing of the first input data. The first feature data may be generated using the source data. The first feature data may be sent to the first speech processing component. In some examples, the first speech processing component may store the first feature data in a first cache local to the first speech processing component.
