Question 1

How do I assign different voices to different speakers?

Accepted Answer

Each item in the `dialogue` array has a `voice_id` field. Set a different voice ID per speaker to give each character a distinct voice. You can pick from the built-in voice list or supply your own ElevenLabs custom voice ID.

Question 2

What languages does Text to Dialogue V3 support?

Accepted Answer

The model supports a wide range of languages including English, French, German, Spanish, Portuguese, Italian, Polish, and more. Pass the appropriate `language_code` (e.g. `en`, `fr`) to improve accuracy and pronunciation for non-English scripts.

Question 3

What does the `stability` parameter control?

Accepted Answer

Stability (0.0–1.0) governs how consistent each voice sounds across the dialogue. A value near 1.0 keeps the voice highly uniform and predictable, while lower values introduce more expressive variation in pitch and delivery.

Question 4

How many speakers can I include in one dialogue?

Accepted Answer

There is no hard cap on the number of speaker turns. You can mix as many speakers as needed within a single request by assigning different voice IDs to different dialogue items.
