## Capabilities

- **Audio tag direction:** Direction sits in the script. This ElevenLabs demonstration breaks into laughter on the pigeon punchline, with tags such as [chuckles] and [laughing].
- **Expressive delivery:** Pace and energy change inside one voice. This sports read climbs from the run into the score, then the crowd.
- **Character performance:** One voice carries attitude and timing. This read plays a scientist who is proud that the last demonstration got out of hand. Voice cloning is not on this route.
- **Multilingual scripts:** The heard language follows the script. This Spanish demonstration does not use a language menu, and this route still generates one preset voice.

## How to use

1. **Write the script:** Enter the approved copy. Use commas and periods for pacing. Prefill from an Example or Key Feature if you want. Nothing runs until you generate.
2. **Set the voice and tags:** The route defaults to Rachel and also offers Aria, Roger, Sarah, and George. Put a tag such as [excited] or [whispers] immediately before the line that should change.
3. **Generate and review:** Confirm the credit estimate, generate, then listen for timing, pronunciation, and delivery. Adjust the tags or the preset and run again before you download.

## Pricing

Generation cost varies by the selected input and output controls. 6 credits per 1,000 characters.

## FAQ

### What is Eleven v4?

Eleven v4 is ElevenLabs’ expressive text-to-speech model. On MixVio you write a script, add audio tags when a line should change, choose a reviewed voice preset, and generate a private audio take. Credits are shown before you run.

### What is Eleven v4 best for?

Use it for launch copy, explainers, and character-style reads where emotion tags and delivery matter as much as the words. This published route is a single-speaker voiceover, generated and reviewed before you download.

### How do audio tags work?

Put direction in square brackets inside the script, for example [excited], [whispers], [laughs], [warm], or [softly], right before the line that should change. Tags are part of the script, not a separate control. Use commas and periods for pacing, and avoid stacking conflicting tags on the same line.

### Which voices can I choose?

The public Eleven v4 route exposes five presets: Rachel, Aria, Roger, Sarah, and George. Rachel is the default. Voice cloning, Professional Voice Clones, and uploaded voices are not on this route.

### Can I generate more than one speaker in a single take?

No. Each Eleven v4 generation uses one preset voice. For a second role, generate another take and edit the files together. Seed Audio 1.0 is the route for a directed sound scene from one brief.

### How long can one Eleven v4 script be?

This published route accepts up to 5,000 characters per generation, matching the fal text limit. Split a longer script into separate takes. MixVio does not stitch context across requests on this route.

### Can I use SSML or a language menu?

Write pauses and delivery as audio tags, not SSML. There is no language picker. The model follows the language of the script. Put a custom pronunciation between slashes when a name or acronym needs one, then review the take.

### What does Eleven v4 output, and how many credits does it use?

Each run returns one private MP3. Pricing is 6 credits per started 1,000 characters, up to 30 credits at 5,000 characters. MixVio shows the exact reservation before submission. Failed runs cost no credits.

### Is Eleven v4 free?

Yes on the Free plan when you have credits. Free voiceovers include an audible MixVio disclosure when that delivery rule is on. Paid-plan takes do not add that disclosure.

### How does Eleven v4 compare with Eleven v3?

Both are single-speaker preset voiceovers with audio tags. Eleven v4 is the newer route at 6 credits per started 1,000 characters. Eleven v3 stays available at 7 credits per started 1,000 characters. Neither route clones a voice or runs a live agent.

### Can I use Eleven v4 outputs commercially?

Paid-plan outputs may be used commercially, subject to the Terms of Service. You must have rights to the script. Free-plan outputs are for evaluation and are not for commercial publishing. Review pronunciation before you publish.
