1. A computer-implemented method for improving speech recognition, the computer-implemented method comprising:
receiving, by one or more processors, a new word to add to a prefix tree;
determining, by the one or more processors, a bonus score for a first transition from a first node to a second node in the prefix tree on condition that the first transition is included in a path of at least one transition representing the new word;
determining, by the one or more processors, a hypothesis score for a hypothesis that corresponds to a speech sequence based, at least in part, on the prefix tree, wherein the hypothesis score adds the bonus score to an initial hypothesis score to determine the hypothesis score; and
responsive to a determination that the hypothesis score exceeds a threshold value, generating, by the one or more processors, an output text sequence for the speech sequence based on the hypothesis.
