flite (Festival Lite) is a small, fast text-to-speech synthesis engine. It converts text to audio using concatenative synthesis, producing speech from recorded fragments.
The engine is designed for embedded systems with limited resources, providing reasonable quality without large runtime requirements. Multiple voices are available with different characteristics.
flite works offline without internet connectivity, making it suitable for accessibility applications and audio generation.
