- A few months back I posted a request for information on algorithms
- for measuring the duration of spoken utterances. I received a number
- of very helpful replies. The paper I found the most useful was:
-
- Rabiner, L.R. and Sambur, M.R., "An algorithm for
- determining the endpoints of isolated utterances," The Bell
- System Technical Journal, 54(2), 1975, pp 297-315.
-
- The paper contains a couple of typos that slowed us down a bit.
- If anyone else plans to implement the Rabiner algorithm, I'll
- be happy to provide our corrections.
-
- In the last couple of days I have run 3 subjects with 10 trials
- each (the input text was "The quick brown fox jumped over the
- lazy dog"). This (very) preliminary pilot study suggests our
- subjects have a durational precision of +/- 5% of their mean
- duration. If the results hold for a statistically valid sample,
- I wonder if a small, speaker independent recognizer with a
- carefully chosen vocabulary might be based on duration alone?
-
- Anyway, my thanks to everyone who replied. Your help was much
- appreciated.
