Model overview
tortoise-tts is a text-to-speech model developed by James Betker, also known as "neonbjb". It is designed to generate highly realistic speech with strong multi-voice capabilities and natural-sounding prosody and intonation. The model is inspired by OpenAI's DALL-E and uses a combination of autoregressive and diffusion models to achieve its results.
Compared to similar models like neon-tts, tortoise-tts aims for more expressive and natural-sounding speech. It can also generate "random" voices that don't correspond to any real speaker, which can be quite fascinating to experiment with. However, the tradeoff is that tortoise-tts is relatively slow, taking several minutes to generate a single sentence on consumer hardware.
Model inputs and outputs
The tortoise-tts model takes in a text prompt and various optional parameters to control the voice and generation process. The key inputs are:
Inputs
- text: The text to be spoken
- voice_a: The primary voice to use, which can be set to "random" for a generated voice
- voice_b and voice_c: Optional secondary and tertiary voices to blend with voice_a
- preset: A set of pre-defined generation settings, such as "fast" for quicker but potentially lower-quality output
- seed: A random seed to ensure reproducible results
- cvvp_amount: A parameter to control the influence of the CVVP model, which can help reduce the likelihood of multiple speakers
The output of the model is a URI pointing to the generated audio file.
Capabilities
tortoise-tts is capable of generating highly realistic and expressive speech from text. It can mimic a wide range of voices, including those of specific speakers, and can also generate entirely new "random" voices. The model is particularly adept at capturing nuanced prosody and intonation, making the speech sound natural and lifelike.
One of the key strengths of tortoise-tts is its ability to blend multiple voices together to create a new composite voice. This allows for interesting experiments in voice synthesis and can lead to unique and unexpected results.
What can I use it for?
tortoise-tts could be useful for a variety of applications that require high-quality text-to-speech, such as audiobook production, voice-over work, or conversational AI assistants. The model's multi-voice capabilities could also be interesting for creative projects like audio drama or sound design.
However, it's important to be mindful of the ethical considerations around voice cloning technology. The maintainer, afiaka87, has addressed these concerns and implemented safeguards, such as a classifier to detect Tortoise-generated audio. Still, it's crucial to use the model responsibly and avoid any potential misuse.
Things to try
One interesting aspect of tortoise-tts is its ability to generate "random" voices that don't correspond to any real speaker. These synthetic voices can be quite captivating and may inspire creative applications or further research into generative voice synthesis.
Experimenting with the blending of multiple voices can also lead to unexpected and fascinating results. By combining different speaker characteristics, you can create unique vocal timbres and expressions.
Additionally, the model's focus on expressive prosody and intonation makes it well-suited for projects that require emotive or nuanced speech, such as audiobooks, podcasts, or interactive voice experiences.

styletts2 is a text-to-speech (TTS) model developed by Yinghao Aaron Li, Cong Han, Vinay S. Raghavan, Gavin Mischler, and Nima Mesgarani. It leverages style diffusion and adversarial training with large speech language models (SLMs) to achieve human-level TTS synthesis. Unlike its predecessor, styletts2 models styles as a latent random variable through diffusion models, allowing it to generate the most suitable style for the text without requiring reference speech. It also employs large pre-trained SLMs, such as WavLM, as discriminators with a novel differentiable duration modeling for end-to-end training, resulting in improved speech naturalness. Model inputs and outputs styletts2 takes in text and generates high-quality speech audio. The model inputs and outputs are as follows: Inputs Text**: The text to be converted to speech. Beta**: A parameter that determines the prosody of the generated speech, with lower values sampling style based on previous or reference speech and higher values sampling more from the text. Alpha**: A parameter that determines the timbre of the generated speech, with lower values sampling style based on previous or reference speech and higher values sampling more from the text. Reference**: An optional reference speech audio to copy the style from. Diffusion Steps**: The number of diffusion steps to use in the generation process, with higher values resulting in better quality but longer generation time. Embedding Scale**: A scaling factor for the text embedding, which can be used to produce more pronounced emotion in the generated speech. Outputs Audio**: The generated speech audio in the form of a URI. Capabilities styletts2 is capable of generating human-level TTS synthesis on both single-speaker and multi-speaker datasets. It surpasses human recordings on the LJSpeech dataset and matches human performance on the VCTK dataset. When trained on the LibriTTS dataset, styletts2 also outperforms previous publicly available models for zero-shot speaker adaptation. What can I use it for? styletts2 can be used for a variety of applications that require high-quality text-to-speech generation, such as audiobook production, voice assistants, language learning tools, and more. The ability to control the prosody and timbre of the generated speech, as well as the option to use reference audio, makes styletts2 a versatile tool for creating personalized and expressive speech output. Things to try One interesting aspect of styletts2 is its ability to perform zero-shot speaker adaptation on the LibriTTS dataset. This means that the model can generate speech in the style of speakers it has not been explicitly trained on, by leveraging the diverse speech synthesis offered by the diffusion model. Developers could explore the limits of this zero-shot adaptation and experiment with fine-tuning the model on new speakers to further improve the quality and diversity of the generated speech.
