OuteTTS: Speech Generation Engine
1. Tutorial Introduction
- Text-to-speech synthesis: Input text to generate natural and fluent speech output, supporting customizable speech speed and intonation.
- Voice cloning: Users can provide reference audio as short as a few seconds and corresponding text to create personalized voices, which is suitable for customized voice assistants, audiobooks and other scenarios.
The model used in this tutorial is the Llama-OuteTTS-1.0-1B model released by Oute AI in March 2025. The parameters have been increased from 350 million to 1 billion, significantly enhancing the voice expressiveness and stability. It also supports localized synthesis in 20 languages, and the cross-language cloning capability has been further optimized.
The computing resources of this tutorial use a single RTX 4090 card. This tutorial mainly provides two usage examples of Default Speaker and Voice Cloning. This tutorial only supports English.

If "Bad Gateway" is displayed, it means the model is initializing. Since the model is large, please wait about 2-3 minutes and refresh the page.
When using the Safari browser, the audio may not be played directly and needs to be downloaded before playing.
Specific parameters:
- Text: Enter the text to be generated.
- Temperature: Scaling factor that controls the randomness of the output.
- Repetition Penalty: Penalty coefficient for suppressing repeated generation.
- Top-k: Limit the number of candidate words generated at each step.
- Top-p: Dynamic candidate word selection (kernel sampling).
- Minimum Probability (min-p): Sets the minimum probability threshold for candidate words.
