kokoro-tts and Kokoros
A Python CLI wrapper with broad format support and a Rust implementation optimizing for inference speed are ecosystem siblings—both leveraging the same underlying Kokoro model but targeting different use cases (accessibility and integration versus performance-critical applications).
About kokoro-tts
nazdridoy/kokoro-tts
A CLI text-to-speech tool using the Kokoro model, supporting multiple languages, voices (with blending), and various input formats including EPUB books and PDF documents.
Builds on ONNX Runtime for efficient inference and leverages chunk-based processing with configurable speech speed and format output (WAV/MP3). The tool integrates stdin piping for workflow composition and intelligently extracts chapter structure from EPUB/PDF files, enabling organized batch processing of long-form content with optional per-chapter audio splitting.
