Linear Prediction Coding

Linear Prediction Coding (LPC) is a method used to analyze and compress speech signals. It works by estimating the current sound sample based on previous samples, assuming speech can be predicted from its past values. Essentially, LPC creates a mathematical model that captures the characteristics of a person's voice, allowing efficient storage or transmission by encoding only the key parameters. The decoder then uses these parameters to reconstruct a close approximation of the original speech. LPC is widely used in speech compression, recognition, and synthesis due to its effectiveness in modeling human speech patterns.
