LPC (Linear Predictive Coding)

Linear Predictive Coding (LPC) is a method used to analyze and synthesize speech by modeling how vocal sounds are produced. It predicts upcoming speech sounds based on previous audio signals, capturing the vocal tract's characteristics like shape and size through mathematical coefficients. Essentially, LPC creates a compact representation of speech, enabling efficient compression and realistic synthesis of voice. This technique is used in applications such as speech compression in telecommunications, voice synthesis, and speaker recognition. By focusing on the predictable patterns in speech, LPC provides a powerful way to analyze and recreate human voice signals accurately.
