What this does

What Voice Design gives you

Voice Design invents the persona your brand needs when you have no talent recording to clone. Preview, refine, and reuse the same synthetic speaker across projects.

  • A persona with no recording session

    Dial in gender, age, accent, and tone when you do not have — or do not want — a clone sample.

  • A library voice you can reuse

    Save the design once and keep ads, courses, and faceless channels on the same brand sound.

  • Distinct characters when you need them

    Spin up separate personas for multi-speaker formats without hiring a cast per episode.

Deep dive

Everything you need to know about AI voice design from scratch

When cloning is the wrong starting point

Cloning assumes you have a person worth copying and the right to copy them. Plenty of projects have neither — faceless channels, product lines that need a neutral brand narrator, training programs that should not sound like one employee forever.

Voice Design starts from attributes instead of a sample. You invent the speaker, then put them to work.

Attributes over endless presets

The useful controls are the ones teams actually decide in a brand meeting: who is speaking, roughly how old they sound, which accent fits the market, and whether the read should feel warm, crisp, or formal.

Braiv keeps the surface area there on purpose. You preview, adjust, and lock a persona into the library — then multilingual TTS does the volume work across scripts and languages.

One designed voice, many outputs

A saved voice is an asset. Use it for weekly ads, course modules, and product explainers so the brand does not drift every time someone picks a different stock voice from a dropdown.

Need a second character for a dialogue-style lesson? Design another. Need the real founder for a keynote cutdown? Switch to expressive voice cloning. Speech is built for that roster, not a single default narrator.

Speech versus Dubbing

Designed voices are for scripts. They do not replace AI video dubbing when the job is localizing a filmed presenter with translation and lip sync. Keep the products straight: Braiv Speech generates the voiceover; Braiv Dubbing localizes the video.

Teams often use both — Speech for net-new narration, Dubbing for catalog localization — on the same AI Credit balance.

The bigger picture

One capability, one step in a longer workflow

Braiv Speech covers the Localize stage. Braiv runs the rest of the sequence on the same recording — so what you make here ends up packaged, localized and published without leaving the platform.

Questions

Frequently asked questions

When should I use Voice Design instead of cloning?
Use Voice Design when you have no reference audio, or when the brand needs a fictional persona rather than a real person’s voice. Use [expressive voice cloning](/features/expressive-voice-cloning) when you want a specific speaker’s identity preserved from a short sample.
What attributes can I control?
Core controls cover gender, age, accent, tone, and speaking style. The point is a directional persona you can preview and iterate — not a dozens-of-sliders sound-design suite that never ships.
Can a designed voice speak multiple languages?
Yes. Designed voices work with [multilingual text to speech](/features/multilingual-text-to-speech) across 80+ languages, so one brand persona can narrate English, Spanish, Portuguese, and more without a new design per market.
Is this for video dubbing or for voiceovers?
Voice Design lives in [Braiv Speech](/products/braiv-speech) for TTS and narration. Designed voices can also be used where Speech feeds localization, but localizing existing on-camera video is the job of [Braiv Dubbing](/products/braiv-dubbing) — cloning and optional lip sync included.
Can I save and share voices with my team?
You can save designed voices to your personal voice library for reuse across projects. Workspace sharing follows your Braiv plan and team settings — the goal is consistency without recreating the persona every time.
Does Voice Design use AI Credits?
Yes. Designing, previewing at volume, and generating audio draw on your shared AI Credit balance. New accounts include credits to evaluate quality before you standardize on a brand voice — see [pricing](/pricing).
