Signal Input/Output

Speech library for Arduino. Generates speech from a fixed vocabulary encoded with LPC.
Talkie comes with over 1000 words of speech data that can be included in your projects. It is a software implementation of the Texas Instruments speech synthesis architecture (Linear Predictive Coding) from the late 1970s / early 1980s. The voice is familiar from Texas Instruments Speak & Spell family of educational products.Copyright 2011 Peter Knight.This library is a reworked version which includes 8 MHz operation and non blocking capabilities as well as a few utilities.The code for the queued non blocking version is based on the fork of Paul Stoffregen. Fixed ESP32 timer bug.Revision History

This library is compatible with the avr, megaavr, samd, esp32, stm32, STM32F1 architectures so you should be able to use it on the following Arduino boards:

Compatibility Note

Note: while the library is supposed to compile correctly on these architectures, it might require specific hardware features that may be available only on some boards.


To use this library, open the Library Manager in the Arduino IDE and install it from there.
