## Description

RealtimeTTS is a real-time text-to-speech engine and stream processor designed to convert text or token streams into audio playback with minimal latency. It provides a programmatic interface for managing audio streams, synthesis progress, and the integration of local or cloud-based speech engines.

The system includes a neural voice cloning tool that generates synthetic speech by extracting acoustic features from reference audio samples. It utilizes a provider-based abstraction to route synthesis requests across different neural models and cloud APIs.

The project covers a range of functional domains including asynchronous playback control, token-stream audio synthesis, and speech synchronization workflows that trigger callbacks at the word or character level. It also supports exporting synthesized audio directly to WAV files for persistent storage.
