Abstract: Devices and techniques are generally described for delayed execution of natural language understanding processes. In various examples, input data is received. In some examples, automatic speech recognition (ASR) data is generated that represents the input data. In some further examples, processing of the ASR data by a first natural language understanding (NLU) process is initiated. In some examples, a first amount of time by which to delay processing of the ASR data by a second NLU process is determined. In at least some examples, processing of the ASR data by the second NLU process is initiated after the first amount of time has elapsed. The first NLU process may be unable to interpret the ASR data. The second NLU process may generate result data that may be stored in memory.
