Low Cost Hardware for Real-Time LPC Analysis and Synthesis of Speech

Linear predictive coding (LPC) of speech is currently being used in applications as diverse as articulation studies, low hit-rate vocoders and "speaking toys'.Consequently.a need exists for simple and inexpensive systems capable of encoding and/or synthesis in real time.The synthesis process is fairly straightforward and many digital hardware implementations atound.Indeed.Texas Instruments have recently developed a
