Ads depend on iteration: a new hook, a shorter cut, a different offer, a version for each market. With traditional voice-over, every change means a new session. With AI, a script change is a regeneration, so you can test more ideas before the budget goes into media. wawie adds the rest of the spot in the same place: music and jingles, sound effects, captions for muted autoplay, and a video editor to cut long and short versions in landscape, portrait or square. This page covers casting, brand voice, localisation and a complete ad workflow.

How do you choose the right voice for an ad?

Casting still matters with AI. Shortlist three to five voices from the library of 1000+, filtered by language, gender and style, including advertising voices, and generate the same script with each. Play them against the picture and the music, because a voice that sounds right on its own can clash with a track. Test the hook line first, then the full read. When a direction wins, regenerate the key lines until the emphasis and pacing land. Download MP3 or WAV for your agency workflow, or build the whole spot in the wawie studio.

Same script, three to five voices, judged against the picture.
Check the hook line before the full read.
Keep the winning voice for the whole campaign.

Can you create a brand voice with voice cloning?

Voice cloning can give a brand one consistent voice, as long as the person behind it agrees. A brand may work with one spokesperson or voice actor; with that person's explicit consent, clone their voice from about 30 seconds of clean speech and reuse it in text to speech, dubbing and dialogue. Every new ad, tutorial or support video then sounds like the same brand, even in another language. Put the agreement in writing, covering scope, duration, markets and payment, and delete the voice from your account when it ends. Never clone a celebrity or anyone else without permission: it is prohibited on wawie and may be illegal.

How do you localise an ad campaign for several markets?

Start from the approved master. For a video ad, video dubbing transcribes, translates and re-voices it into 24+ languages while keeping the original timing, and a consented brand voice can carry across languages. For audio spots or new edits, generate each market's voice-over from a locally adapted script with text to speech, in about 30 languages and several accents. Then caption each version for muted autoplay and add market-specific end cards in the studio. Have a native marketer review claims, prices and legal lines, since these often need local wording, not just translation.

Video ads: dub the master into 24+ languages.
Audio spots: generate each language from an adapted script.
Caption every version for sound-off viewing.

How does an ad go from script to localised versions in wawie?

Draft and cast: Create a free account, paste the script into text to speech, and generate it with three to five shortlisted voices. Compare them against the picture and keep the one that fits the brand.
Build the soundtrack: Generate a jingle from a few lines of lyrics with the song generator, or an instrumental bed with the music generator, then add sound effects such as a logo sting or a product sound.
Cut the spot: Assemble voice, footage, music and effects on the studio timeline in the format you need, landscape, portrait or square, and cut long and short versions of the same ad.
Caption and check: Add automatic subtitles for viewers who watch without sound and style them to match the brand. The pre-export check flags captions that read too fast or a mix that is too loud.
Localise and iterate: Export each version as an MP4, then dub the approved master into 24+ languages. When results come in, change a line, regenerate it in the same voice, and export again.

Frequently asked questions

Can I use AI voice-overs in paid advertising?

Yes. Content you generate in wawie from your own script is yours to use within the model providers' terms, and commercial use is included from Wawie Start at EUR 4.99 a month; the free plan is for trying the tools. You remain responsible for the script, any claims it makes, and the rights to any footage, logo or voice you supply. Check each ad platform's rules on AI-generated content.

How do I create a consistent brand voice?

Choose one voice from the library and use it for every ad, or clone the voice of a spokesperson who gives explicit consent, from about 30 seconds of clean speech. The cloned voice stays private to your account and can narrate new scripts, dub videos into other languages and voice dialogue scenes, so your brand sounds the same across formats. Record the consent terms in writing.

Can wawie make a jingle for my brand?

Yes. The AI song generator turns your lyrics, or a theme it writes lyrics from, into a sung song with music in the style and mood you choose, for example upbeat pop or warm acoustic. Keep the lyrics short and put the brand name in the hook. Generate several takes, keep the best, and trim it in the studio. Songs are royalty-free for commercial use on a paid plan, within the providers' terms.

How many languages can I localise an ad into?

Video dubbing covers 24+ target languages and keeps the original timing, so a short spot still lands on its cuts. For audio ads or re-edited versions, text to speech offers about 30 languages with several accents. Adapt the script to each market rather than translating it word for word, and have a native speaker check claims, prices and legal lines before the ad goes live.

Is AI voice-over cheaper than a studio for ads?

Usually, yes. Industry estimates suggest AI production can cut voice-over costs by roughly 60 to 90% versus a traditional studio, and a revision costs a regeneration instead of a new session. In wawie, one subscription from EUR 4.99 a month covers voices, cloning, music, sound effects, dubbing and editing, which wawie estimates is at least 73% cheaper than paying for comparable single-purpose tools separately.

Can I test several ad scripts quickly?

Yes, this is where AI helps most. Paste each script variant, generate it in the same voice, and compare them against the cut. Changing one line means regenerating only that line, not the whole read. The cost of each generation is shown before you launch it, so a team can test hooks, offers and calls to action without booking a studio. You can start free with 5,000 one-time credits, no card needed.
