Abstract
A speech is recognized using ACF factors extracted from running autocorrelation functions calculated from the speech. The extracted ACF factors are a W(width of ACF amplitude around zero-delay origin), a W(maximum value of the W), a τ(pitch period), a φ(pitch strength), and a Δφ/Δt (rate of the pitch strength change). Syllables in the speech are identified by comparing the ACF factors with templates stored in a database.
