1. A method comprising: monitoring an audio stream associated with a non-tactile gesture input stream; identifying a speech event in an audio stream; determining a temporal window associated with a time of the speech event, wherein the temporal window extends forward and backward from the time of the speech event; analyzing, via a processor, data from the non-tactile gesture input stream within the temporal window to identify, based on the speech event, a non-tactile gesture event; and processing the speech event and the non-tactile gesture event to produce a multimodal command.
