//! IndexTTS - High-performance Text-to-Speech Engine in Pure Rust
//!
//! This is a Rust implementation of the IndexTTS system, providing
//! zero-shot multi-lingual text-to-speech synthesis with emotion control.
//!
//! # Features
//! - High-performance audio processing with SIMD optimizations
//! - Multi-language support (Chinese, English, mixed)
//! - Emotion control via vectors or text
//! - Speaker voice cloning from reference audio
//! - Efficient memory usage with zero-copy operations
//!
//! # Example
//! ```no_run
//! use indextts::{IndexTTS, Config};
//! use indextts::pipeline::SynthesisOptions;
//!
//! let config = Config::load("config.yaml").unwrap();
//! let tts = IndexTTS::new(config).unwrap();
//!
//! let options = SynthesisOptions::default();
//! tts.synthesize("Hello world", "speaker.wav", &options).unwrap();
//! ```
