7. A system comprising: a processor; and a computer-readable storage medium having instructions stored which, when executed by the processor, result in the processor performing operations comprising: recognizing, using a current phonotactic model, phonemes using a combination of speech and touchscreen input from a first user input, to yield recognized phonemes; transforming a prior probability distribution from a first domain to a second domain without speech transcriptions to yield a transformed prior probability distribution, wherein the first domain and the second domain comprise word sequence spaces; creating a new phonotactic model associated with the second domain using morphemes detected from: the recognized phonemes; and the transformed prior probability distribution associated with the first domain, wherein the first domain is distinct from the second domain; replacing the current phonotactic model with the new phonotactic model in a database; recognizing further phonemes in second input using the new phototactic model.
