Patent Document ID: 10152298
Application ID: 14754181

Base Claim:
1. A computer-implemented method of determining a confidence score for a potential speech recognition result, the method comprising: determining a first group of words, wherein each word of the first group of words was predicted a first number of times during automatic speech recognition (ASR) testing; determining a first total number of predictions for the first group, the first total number of predictions corresponding to the first number multiplied by a number of words in the first group of words; determining a first total number of correct results for the first group, the first total number of correct results corresponding to a cumulative number of times each word of the first group was correctly predicted during the ASR testing; determining a first group prior probability for the first group by dividing the first total number of correct results by the first total number of predictions; determining a first prior probability for a first word using the first group prior probability; receiving audio data corresponding to a first utterance; and performing first ASR processing on the audio data to generate a hypothesis, the hypothesis including the first word, wherein performing first ASR processing further comprises determining a confidence score for the hypothesis using the first prior probability for the first word.

Claim 2:
2. The computer-implemented method of claim 1 , further comprising: determining the first number of times is equal to one; determining that the first word was not predicted during the ASR testing; and determining to use the first group prior probability for the first word.
