US Patent 11756538 Lower latency speech processing

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.
