OuteTTS-0.1-350M is a text-to-speech synthesis technology based on a pure language model, requiring no external adapters or complex architectures, achieving high-quality voice synthesis through carefully designed prompts and audio tokenization. This model is based on the LLaMa architecture, utilizing 350 million parameters to demonstrate the potential for direct voice synthesis using language models. It processes audio in three steps: using WavTokenizer for audio tokenization, creating precise word-to-audio mappings through CTC forced alignment, and generating structured prompts that follow specific formats. The key advantages of OuteTTS include a pure language modeling approach, voice cloning capabilities, and compatibility with llama.cpp and GGUF formats.

Fish Agent V0.1 3B is a groundbreaking speech-to-speech model capable of capturing and generating environmental audio information with unprecedented accuracy. The model utilizes a non-semantic tagging architecture, eliminating the need for traditional semantic encoders/decoders. Additionally, it is a cutting-edge text-to-speech (TTS) model trained on 700,000 hours of multilingual audio content. As a continuation of the Qwen-2.5-3B-Instruct pre-trained version, it has been trained on 200 billion speech and text tags. The model supports eight languages, including English and Chinese, with approximately 300,000 hours of training data for each of these languages and around 20,000 hours for others.

BASE TTS is a large-scale text-to-speech synthesis model developed by Amazon. It employs an auto-regressive transformer with over 1 billion parameters to convert text into speech codes and then generates speech waveforms using a convolutional decoder.
