# Overview

After you have added or created some new characters, you can start using them to generate some speech! To perform **Text-to-Speech (TTS)**, please go to the [Vocu Studio](https://app.vocu.ai/generate) page, add or edit the text you need there, assign characters (speakers) to paragraphs, then click the **Start Generation** button in the **Generation Configuration** tab and you're done!

It's simple, isn't it? However, there are a few things you may need to pay attention to:

* Due to the characteristics of AI models, the results generated each time are slightly different. You can try several times to get ideal or more creative effects.
* **Generation parameters** have a great impact on the final generation effect. Currently, based on various tests and optimizations, we have set different preset templates, each corresponding to different optimization directions. You can choose different generation parameters by adjusting presets to find the most suitable effect for you.
* Different versions of models may have some shortcomings and limitations. We recommend that you refer to [**Model List**](/introduction/models.md) to learn about the introduction of each model.
