Ito

Ito is a text-to-speech software that runs entirely on the ESP32-S3 microcontroller, delivering natural-sounding, streaming speech synthesis with no cloud dependency and no neural processing unit required. It models English text-to-speech in a small footprint optimized for embedded systems, supporting real-time output and open source usage under GPLv3 for hobby, research, and education, with commercial and small team use available through collaboration.
