Classification: CPC G | IPC G

Claim 14:
15. A system for performing speech analytics, comprising:
a memory comprising executable instructions;
a processor configured to execute the executable instructions and cause the system to:
produce a set of meaning units by zoning a digital transcript file of audio data, wherein the instructions to produce the set of meaning units further cause the system to:
identify a plurality of utterances within the digital transcript file representing audio data, performed by applying an acoustic model to the audio data or a linguistic model to the digital transcript file;
for each utterance having fewer than a predetermined number of words, define the utterance as a meaning unit for the set of meaning units;
for each utterance having more than a predetermined number of words, define the utterance as comprising more than one meaning unit and parse data associated with the utterance into data windows of predetermined length of N words for determination of a meaning unit boundary within the utterance; and
for each data window, for each word W1 . . . N within each data window, calculate a probability and entropy that the each word W1 . . . N is the meaning unit boundary by applying another n-gram linguistic model to the data window, the probability and the entropy indicative of words indicative of a change in speaker, words appearing before or after a particular word, word doublets or triplets are spoken together, or a likelihood of a short combination or words;
split each data window into meaning units at a word Wk having a maximum calculated probability of being the meaning unit boundary, such that each meaning unit includes the word Wk having the highest probability indicating a new meaning unit; and
apply automated speech analytics to the set of meaning units.
