# Audio models
Audio is often the final piece of your workflow, adding the emotional depth and immersion that turns good content into exceptional content.
Whether you're creating UGC videos, product explainers, social ads, or brand storytelling, the right audio transforms how your audience experiences your message.
We've curated audio models that balance quality, speed, and control for different marketing needs.
## AI Speech

**What makes it exceptional:**
* **70+ languages:** Maintain consistent voice quality and personality across all supported languages
* **Audio tags:** Control emotion, pacing, and delivery with inline tags like `[excited]`, `[whispers]`, `[laughs]`, `[dramatic]`

**How to make the most of it:**
1. **Pick your voice:** Browse our curated voice library, we've shortlisted our favorite voices ("Pletor's picks") for faster selection and iteration:
2. **Test the voice:** Generate a short sample with your brand's typical messaging to verify fit
3. **Enhance with audio tags:** Use our dedicated [Creative Assistant](/build-agents/nodes/ai-nodes/text-assistants.md) to automatically structure your script with emotion and pacing tags (*or* [*read about them*](https://elevenlabs.io/blog/v3-audiotags) *yourself)*.
4. **Fine-tune:** Adjust the Stability parameter to control consistency (higher = more predictable, lower = more expressive variation)
5. **Couple it with the right video model**, depending on your use case (e.g., [Veed Fabric](https://docs.pletor.ai/ai-model-library/video-models/lip-sync-video-models#veed-fabric-1.0-popular) for UGC videos)
