Linear Predictive Coding (LPC) is a popular technique in speech signal processing for efficiently representing the spectral envelope of a speech signal. The MATLAB implementation of LPC involves several steps: pre-emphasis to balance high and low-frequency components, frame blocking to segment the ...
A major source of audible distortion in current low-bit-rate speech coding algorithms is an inaccurate degree of periodicity of the voiced speech signal. I... WB Kleijn - IEEE 被引量: 145发表: 1991年 Robust and fast code-excited linear predictive coding of speech signals A description is gi...

In digital signal processing, linear prediction is often called linear predictive coding (LPC). DSP System Toolbox offers Simulink®blocks to convert linear prediction coefficients to cepstral coefficients, reflection coefficients (RC), autocorrelation coefficients, line spectral frequencies (LSF), and vi...
To synthesize some vowels (monophthongs) using the source-filter model of speech production. The formant structure of each vowel will be estimated directly from a real speech sample, using linear predictive coding (LPC). Synthesized vowels can then be generated by passing a periodic impulse train ...
