How to use the voice designer

STEP 1

Define Your Voice Brief

Paste a sample script and describe personality, emotion, energy, audience, and context (e.g., calm assistant, confident ad read). Add notes for pacing, emphasis, pronunciations, and compliance where needed.

STEP 2

Choose a Base Voice & Style

Select a model and base voice as your starting point. Apply tone directives (warm, authoritative, playful, cinematic) and optional style tags or SSML-like cues for breaths, pauses, and emphasis.

STEP 3

Generate & Export Production Audio

Generate takes, review critically, refine tone and timing, then regenerate. Export clean WAV/MP3, add SFX/BGM, or deploy via API to products, videos, and interactive experiences.
