7. A method, comprising: receiving a user utterance from a user using a computing device; identifying potential matching symbols for the user utterance; ranking, using a predictive language model, the potential matching symbols by relative probabilities of the potential matching symbols, wherein the relative probabilities are determined by the predictive language model using a dataset, the dataset comprising: confirmed user entries comprising words or phrases that were previously entered by the user into the computing device and confirmed by the user, and a number of occurrences of the confirmed user entries in the dataset; and causing the potential matching symbols to be presented to the user on the computing device in a ranked order based upon the probabilities of the potential matching symbols, wherein the relative probabilities of the potential matching symbols are weighted based upon the number of occurrences of the confirmed user entries in the dataset.
