Relationship Between Zero-Crossing Measurements for Speech Analysis and Recognition
M.R. Ito · The Journal of the Acoustical Society of America · 1972
Three types of zero-crossing measurements—(i) average zero-crossing rate, (2) density of time intervals between zero-crossings, and (3) excess-threshold duration—are related theoretically. It is shown that measurement types 1 and 3 can be derived from the type 2 measurement. Measurement types 1 and 3 cannot be directly related, but it is shown that the type 2 measurement can be derived from the type 3 measurement.
