4. The method of claim 1 , wherein the morphemes in the speech are derived from an action of a user.
1. A method comprising: recognizing, via a processor and with 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, via the processor, 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, via the processor, the current phonotactic model with the new phonotactic model in a database; recognizing, via the processor, further phonemes in second input using the new phototactic model.
