Abstract
In a method for determining likelihood of appearance of keywords in a spoken utterance as part of a keyword spotting system of a speech recognizer, a new scoring technique is provided wherein a confidence score is computed as a probability of observing the keyword in a sequence of words given the observations. The corresponding confidence scores are the probability of the keyword appearing in any word sequence given the observations. In a specific embodiment, the technique involves hypothesizing a keyword whenever it appears in any of the 'N-Best' word lists with a confidence score that is computed by summing the likelihoods for all hypotheses that contain the keyword, normalized by dividing by the sum of all hypothesis likelihoods in the 'N-best' list.
