1. A method for selecting a sentence, formed from a sequence of hypothesized words, from a plurality of hypothesized sentences, comprising the steps of: (a) determining beginning and end points for each hypothesized word in each hypothesized sentence; (b) determining a word error for each hypothesized word in each hypothesized sentence which indicates a likelihood of the hypothesized word having been incorrectly hypothesized; (c) determining whether any gaps occur between consecutive hypothesized words in each hypothesized sentence; (d) assigning error values to any gaps determined in step (c); (e) determining whether any overlap occurs between consecutive hypothesized words in each hypothesized sentence; (f) assigning error values to any overlaps determined in step (e); (g) summing the word errors, gap errors and overlap errors for each hypothesized sentence, and (h) generating an indicator of the selected sentences as being the hypothesized sentence with the smallest sum as determined in step (g).
