# Voice Blending
Blend multiple AI voice seeds to create unique hybrid voices in ACE Studio.
## What Is Voice Blending?
With this feature, you can blend different voices to create a hybrid voice by AI.
Voice blending allows you to combine multiple voice seeds under the same vocal synth model version.
You can manually save your customized blended presets into Voice Library.
To use a blended preset, simply drag it to the canvas or onto the track header.
## Blending Voices
Click on the track header to open the track panel. There is a module called "blend voice" in the track panel.
* Click the + button to add different voice seeds from the pop-up list.
* Adjust the blending ratio by dragging vertically on each fader.
* Right-click on a seed to delete or copy it.
* Copy and paste the blending recipe to another singer track using the settings menu at the top-right corner of the panel.
{% hint style="info" %}
In Verse24 and earlier, blending involves two separate dimensions: Timbre and Style.\
By default, their ratios are synced. You can un-sync by clicking the chain button in the middle of each seed for independent adjustments.
{% endhint %}
### Blending voices in Unison Mode
You can blend voices for each voice within [Unison Mode for vocals](/ai-vocal-synth/creating-ai-vocals/unison-mode-for-vocals.md). The **Blend voices** module corresponds to the voice selected in the voice list.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.acestudio.ai/ai-vocal-synth/creating-ai-vocals/voice-blending.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
