摘要：
An improved acoustic signal recognition system, suitable for speech or other acoustic pattern recognition, features data compression of original signal data to reduce requirements for data storage and comparison, as well as reduce recognition errors, the data is compressed by discarding signal spectral samples which do not vary from previously stored spectral samples by a threshold amount, using difference-gating.
