This project allows the Arduino (an 8-bit MCU) to generate human-like speech without dedicated hardware chips.
Talkie Library: Uses the Talkie library, which implements Linear Predictive Coding (LPC). The library contains a vocabulary of pre-defined "phonemes" and "allophones."
Audio Output: The speech signal is generated via standard PWM (Pulse Width Modulation) on a digital pin.
Hardware Integration
Output Stage: The high-frequency PWM signal passes through a simple RC filter to smooth the audio before entering an LM386 amplifier.
Utility: This creates a low-cost "Voice" for interactive robots, safety alarms, or accessibility tools, proving that even limited 8-bit processors can perform complex digital signal processing (DSP).
