WebSep 10, 2024 · 2.2.3 Frequency domain linear prediction. Another time envelope can be applied to the speech signal is the FDLP (frequency domain linear prediction), which is reliable for time-adaptive behaviour. The idea behind this technique is to use frequency-domain dual of time-domain to extract the envelope by using linear prediction. Webinstead of by time, hence the name "frequency domain." The analysis in this paper makes three specific assumptions. First, the predictor must be linear. A basic result of linear systems theory states that any sinusoidal input into a linear system results in an output of another sinusoid of the same frequency, but with different magnitude and phase.
