Long-term Predicted Excitation Coding

Long-term Predicted Excitation Coding (LPEC) is a technique used in speech coding and other audio processing applications to efficiently represent and transmit voice signals. It is particularly relevant in contexts where bandwidth is limited, such as in telecommunications or streaming applications. ### Key Concepts of LPEC: 1. **Excitation Coding**: This refers to the method of representing the excitation signal that drives the vocal tract model in speech synthesis.
