Software for statistical analysis of speech
View Patent ↗Computer-implemented methods and apparatus are provided to facilitate the recognition of the content of a body of speech data. In one embodiment, a method for analyzing verbal communication is provided, comprising acts of producing an electronic recording of a plurality of spoken words; processing the electronic recording to identify a plurality of word alternatives for each of the spoken words, each of the plurality of word alternatives being identified by comparing a portion of the electronic recording with a lexicon, and each of the plurality of word alternatives being assigned a probability of correctly identifying a spoken word; loading the word alternatives and the probabilities to a database for subsequent analysis; and examining the word alternatives and the probabilities to determine at least one characteristic of the plurality of spoken words.
1. A method for analyzing verbal communication, the method comprising acts of:
(A) producing an electronic recording of a plurality of spoken words;
(B) processing the electronic recording to identify a plurality of word alternatives for each of the spoken words, each of the plurality of word alternatives being identified by comparing a portion of the electronic recording with a lexicon, each of the plurality of word alternatives being assigned a probability of correctly identifying a spoken word;
(C) loading the word alternatives and the probabilities to a database for subsequent analysis; and
(D) examining the word alternatives and the probabilities to determine at least one characteristic of the plurality of spoken words;
wherein the at least one characteristic includes a frequency with which a first word alternative occurs within the plurality of spoken words; and
wherein the at least one characteristic further includes a frequency with which a second word alternative occurs within the plurality of spoken words, and a comparison of the frequencies of the first word alternative and the second word alternative.
2. The method of claim 1 , wherein the at least one characteristic further includes a comparison of the frequencies of the first word alternative and the second word alternative in a plurality of time periods.
3. The method of claim 1 , wherein the at least one characteristic includes a presence of a pattern, the pattern comprising a defined sequence of word alternatives.
4. The method of claim 3 , wherein the pattern is defined by a human user.
5. The method of claim 4 , wherein the pattern is defined using a graphical user interface.
6. The method of claim 1 , further comprising an act, performed before the act (B), comprising modifying the lexicon.
7. The method of claim 1 , wherein the act (C) further comprises loading the word alternatives and the probabilities to a database.
8. A computer-readable medium having instructions recorded thereon, which instructions, when executed by a computer, perform a method for analyzing verbal communication, the method comprising acts of:
(A) producing an electronic recording of a plurality of spoken words;
(B) processing the electronic recording to identify a plurality of word alternatives for each of the spoken words, each of the plurality of words alternatives being identified by comparing a portion of the electronic recording with a lexicon, each of the plurality of word alternatives being assigned a probability of correctly identifying a spoken word;
(C) loading the word alternatives and the probabilities to a database for subsequent analysis; and
(D) examining the word alternatives and the probabilities to determine at least one characteristic of the plurality of spoken words.
wherein the at least one characteristic includes a frequency with which a first word alternative occurs within the plurality of spoken words; and
wherein the at least one characteristic further includes a frequency with which a second word alternative occurs within the plurality of spoken words, and a comparison of the frequencies of the first word alternative and the second word alternative.
9. The method of claim 8 , wherein the at least one characteristic further includes a comparison of the frequencies of the first word alternative and the second word alternative in a plurality of time periods.
10. The method of claim 8 , wherein the at least one characteristic includes a presence of a pattern, the pattern comprising a defined sequence of word alternatives.
11. The method of claim 8 , wherein the pattern is defined by a human user.
12. The method of claim 11 , wherein the pattern is defined using a graphical user interface.
13. The method of claim 8 , further comprising an act, performed before the act (B), comprising modifying the lexicon.
14. The method of claim 8 , wherein the act (C) further comprises loading the word alternatives and the probabilities to a database.
