Linear Predictive Coding (LPC)

Linear Predictive Coding (LPC) is a technique used to analyze and reproduce speech signals efficiently. It models the current sound sample as a weighted sum of past samples, effectively capturing the speech’s underlying vocal tract characteristics. By estimating these weights (parameters), LPC can compress speech data and synthesize speech that sounds natural. It's widely used in speech compression, recognition, and synthesis because it provides a compact representation of speech with high quality and efficiency.
