Relaxed code-excited linear prediction
open-in-new
<p>Relaxed code-excited linear prediction (RCELP) is a method used in some advanced <a href="/facts/Speech_codec/xs5gvMXq">speech codecs</a>. The RCELP <a href="/facts/Algorithm/fnl5NmRt">algorithm</a> does not attempt to match the original signal exactly. Instead, it matches a time-warped version of this original signal that conforms to a simplified <a href="/facts/Pitch_contour/IUPDpExo">pitch contour</a>. </p>
