1. A method comprising:

  • outputting, by a computing device and for display, a graphical keyboard comprising a plurality of keys;

    receiving, by the computing device, an indication of a gesture detected at a presence-sensitive input device;

    determining, by the computing device, based at least in part on the indication of the gesture, a spatial model probability associated with one or more keys from the plurality of keys;

    adjusting, by the computing device, based on at least one characteristic of the gesture, the spatial model probability associated with the one or more keys from the plurality of keys, wherein the at least one characteristic of the gesture includes a speed of a portion of the gesture;

    determining, by the computing device, based on the adjusted spatial model probability associated with the one or more keys from the plurality of keys, a character string; and

    responsive to determining that the character string is not included in a lexicon and that the adjusted spatial model probability associated with the one or more keys from the plurality of keys exceeds a probability threshold, outputting, by the computing device and for display, the character string.
