摘要
A speech pattern from a noisy environment is analyzed to form a representative sequence of speech parameter signals. The noise-contaminated speech pattern is partitioned into successive time frame intervals. A predictive error signal is generated for each successive interval responsive to the noise contaminated speech of the interval and an estimate of the contaminating noise. Predictive parameter signals are selected to minimize the time frame predictive error signal so that accurate digital codes representative of the speech are generated.
