1. A method of operating a computing device having a soft keyboard, the method comprising: determining at least one characteristic of at least one of: (i) an average time between taps or (ii) a style of the soft keyboard; determining, for each of a plurality of keys on the soft keyboard, a mean of a probability distribution function and an indication of a spread of the probability distribution function, the mean and the indication of the spread being determined based on the at least one determined characteristic; with a soft keyboard interface executing on at least one processing circuit: in response to a first input received through the soft keyboard: generating a first set of probabilities based on the probability distribution functions, wherein the first set of probabilities includes: a first indication indicative of a probability that a first key was targeted for the first input; and a second indication indicative of a probability that a second key was targeted for the first input; providing the first set of probabilities to a text prediction engine executing on the at least one processing circuit; and in response to a second input received through the soft keyboard: generating a second set of probabilities based on the probability distribution functions, wherein the second set of probabilities includes: a third indication indicative of a probability that a third key was targeted for the second input; and a fourth indication indicative of a probability that a fourth key was targeted for the second input; providing the second set of probabilities to the text prediction engine executing on the at least one processing circuit; and with the text prediction engine, predicting an intended word based on: the first indication indicative of the probability that the first key was targeted for the first input; the second indication indicative of the probability that the second key was targeted for the first input; the third indication indicative of the probability that the third key was targeted for the second input; and the fourth indication indicative of the probability that the fourth key was targeted for the second input.
