30. A method as in claim 29 including the further step of: limiting the number of labels examined in determining the probability of .PHI..sub.n for each phonetic element to a maximum of J labels.
30. A method as in claim 29 including the further step of: limiting the number of labels examined in determining the probability of .PHI..sub.n for each phonetic element to a maximum of J labels. 31. A method as in claim 30 wherein the end time probabilities are determined for only the first J+K incoming labels where K is the number of states in the corresponding phonetic element.
