Preguntas frecuentes

Preguntas frecuentes

How do I create a multi-hablante conversation?

Define each voice in the `speakers` list con a unique `speaker_id` (in "Speaker N" format), then reference those IDs in your `dialogue_turns`. The model renders each line in that hablante's assigned voice, accent, style, y pace.

¿I control emotion y pacing?

Sí. Cada hablante has `style` (Vocal Smile, Newscaster, Whisper, Empathetic, Promo/Hype, Deadpan) y `pace` (Natural, Rapid Fire, The Drift, Staccato) settings. Puedes also embed inline tone tags like [whispers], [shouting], o [determination] directly in the diálogo text.

What voices y accents are disponible?

Hay 30 prebuilt voices (Zephyr, Fenrir, Puck, Kore, y more) y 8 accents including Neutral, American variants, British (RP), British (Brixton), Transatlantic, y Australian.
