4. A method, comprising: receiving audio data, wherein the receiving is performed by at least one automated speech recognition (ASR) device configured to convert the audio data into text data, the at least one ASR device comprising at least one ASR module; determining, by the at least one ASR module, a sequence of speech units represented in a portion of the audio data; determining, by the at least one ASR module, a first duration of the sequence of speech units; determining, by the at least one ASR module and using the first duration, an expected duration of a single speech unit in the sequence of speech units; determining, by the at least one ASR module, a second duration of the single speech unit; determining, by the at least one ASR module, a duration score of the single speech unit, the duration score corresponding to the second duration in relation to the expected duration; determining, by the at least one ASR module, a speech recognition result based at least in part on the duration score of the single speech unit, wherein the speech recognition result is the text data corresponding to the received audio data representing speech; and causing a command to be executed using the text data.

The method of claim 4 , further comprising normalizing the duration score using a number of speech units in an utterance comprising the single speech unit.
