Researchers have developed TontaubeV1, an open-weight text-to-speech (TTS) model capable of generating long-form, expressive speech. This character-level model, built upon a Qwen3-1.7B checkpoint and the DualCodec audio codec, supports low-latency local inference and zero-shot voice cloning. Key innovations include character-level tokenization, which reportedly improves robustness over standard BPE tokenizers for TTS tasks, and a novel chunking and position scheme that aligns text and audio streams more effectively for continuous generation.
