25. The computing system of claim 24 , wherein processing the second audio data to determine the second pause duration value further comprises: performing automatic speech recognition processing on the second audio data to determine a second hypothesis including one or more of at least one second word or a representation of at least one second word potentially corresponding to the second audio data; determining that a second portion of the second audio data corresponds to speech; determining a third value representing a third time duration of the second portion of the second audio data; determining a second duration weight factor based at least in part on the third value; determining, in the second hypothesis, a representation of second non-speech, the second non-speech following the second portion of the second audio data; determining a fourth value representing a fourth time duration corresponding to the second non-speech; and determining the second pause duration value by using the second duration weight factor to adjust the fourth value.
25. The computing system of claim 24 , wherein processing the second audio data to determine the second pause duration value further comprises: performing automatic speech recognition processing on the second audio data to determine a second hypothesis including one or more of at least one second word or a representation of at least one second word potentially corresponding to the second audio data; determining that a second portion of the second audio data corresponds to speech; determining a third value representing a third time duration of the second portion of the second audio data; determining a second duration weight factor based at least in part on the third value; determining, in the second hypothesis, a representation of second non-speech, the second non-speech following the second portion of the second audio data; determining a fourth value representing a fourth time duration corresponding to the second non-speech; and determining the second pause duration value by using the second duration weight factor to adjust the fourth value. 26. The computing system of claim 25 , wherein: performing automatic speech recognition processing on the first audio data further comprises calculating a first probability that the first hypothesis corresponds to an utterance represented in the first audio data; determining the first pause duration value further comprises determining the first pause duration value based at least in part on the first probability; performing automatic speech recognition processing on the second audio data further comprises calculating a second probability that the second hypothesis corresponds to an utterance represented in the second audio data; and determining the second pause duration value further comprises determining the second pause duration value based at least in part on the second probability.
