1. A computer-implemented method comprising: classifying a received phrase as an incomplete phrase for performing a voice action based at least on determining that (i) the voice action requires a parameter, and (ii) that no term of the phrase corresponds to the parameter; in response to classifying the phrase as an incomplete phrase, generating a prompt for entry of the parameter; in response to the prompt, receiving data indicating an entered parameter; and providing, for output, a suggested complete phrase for performing the voice action using the entered parameter, the suggested complete phrase comprising a phrase that when subsequently received causes the voice action to be performed without prompting for the entry of the parameter after determining that the suggested complete phrase includes one or more terms that correspond to the voice action.
