An Arduino-Based Talking Calorimeter for Inclusive Lab Activities

“…In the 1980s, Texas Instruments developed the first speech synthesizers. TMS52xx was used in devices for simulating speech such as Acorn Computer, Apple II Echo 2, and BBC Micro. , This chip was based on a mathematical model called Linear Predict Coding (LPC) . LPC gives a compressed representation of the spectral envelope of the speech signal.…”

“…13,14 This chip was based on a mathematical model called Linear Predict Coding (LPC). 15 LPC gives a compressed representation of the spectral envelope of the speech signal. It assumes that the signal can be predicted by a linear combination of previous samples (p) according to the following expression: 16 x a x e…”
