11. A system comprising: a processor; and a computer-readable storage medium having instructions stored which, when executed by the processor, cause the processor to perform operations comprising: monitoring an audio stream associated with a non-tactile gesture input stream; identifying a speech event, in the audio stream, from a first user; 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 data from the non-tactile gesture input stream within the temporal window to identify, based on the speech event, a non-tactile gesture event; identifying clarifying information, in the audio stream, about the speech event from a second user; applying the clarifying information to the speech event to yield a clarification; and processing, based on the clarification, the speech event and the non-tactile gesture event to produce a multimodal command.
