LPC Synthesis

LPC (Linear Predictive Coding) synthesis is a method to generate speech sounds by modeling the vocal tract as a filter that shapes a simple sound source, like a buzzing or pulse train. It analyzes recorded speech to identify parameters that describe this filter and the source. To synthesize speech, LPC uses these parameters to recreate the filter and then combines it with the sound source, producing speech that closely resembles natural human voice. Essentially, LPC synthesis captures the characteristics of speech and rebuilds it efficiently, enabling realistic voice generation in applications like speech compression and text-to-speech systems.
