1. A method comprising: receiving a first voice input from a user device; generating a first recognition output; receiving a user selection of one or more terms in the first recognition output; receiving a second voice input spelling a correction of the user selection, the second voice input including a series of letters; determining a corrected recognition output for the selected portion, wherein determining a corrected recognition output includes: initiating parallel voice recognition processes on the second voice input including a letter specific voice recognition process and a base voice recognition process, scoring recognition outputs generated for each of the parallel voice recognition processes, wherein the letter specific voice recognition process is scored based on the recognition of the spelled correction and wherein the base voice recognition process is scored based on the recognition for the spelled correction and one or more other terms of the first recognition output, and selecting the corrected recognition output based on the scores; and providing a second recognition output that merges the first recognition output and the corrected recognition output.
