Voice Every Ad Variant in 70+ Languages with ElevenLabs and Soku AI
ElevenLabs turns a script into a finished, emotionally directed read in seconds — in 70+ languages, in a voice you cloned or designed. Soku AI turns those reads into ad variants, deploys them across Meta, Google, and TikTok, and tells you which voice actually converted.
ElevenLabs at a Glance
ElevenLabs is a voice AI company whose speech models have become the default for synthetic voiceover in media and marketing production. Its flagship Eleven v3 model produces speech with genuine emotional range and contextual understanding, and introduced inline audio tags — you write the direction into the script and the model performs it.
Core Capabilities
Eleven v3 with Audio Tags
Write inline direction such as [whispers], [excited] or [sighs] straight into the script and the model performs it, with contextual emotional range across languages.
Turns read energy into a one-line A/B test instead of a re-booking.
70+ Languages, One Voice
Generate the same script across dozens of markets while keeping a single voice identity, so localization stops being a casting exercise.
Instant Voice Cloning
Build a usable clone from roughly a minute of source audio. Available from the Starter plan, which is also where the commercial license begins.
Clone only voices you have written permission to use.
Professional Voice Cloning
Train a high-fidelity model from longer samples for a genuine brand voice that holds up across a whole campaign. Available from the Creator plan up.
Voice Design from a Prompt
Describe a voice in text and get a new synthetic one — no source recording, no talent, no rights question about a real person's likeness.
Text to Dialogue API
Generate multi-speaker scripts with natural turn-taking and emotional range, useful for testimonial-style and conversational ad formats.
Dubbing Studio
Translate existing video while preserving the original speaker's voice, so a proven creative can enter a new market without a reshoot.
Streaming and Sound Design
Streaming starts playback before generation finishes for low-latency use, and sound-effect and music generation cover the bed and stings alongside the voice track.
From Brief to Optimized Ad in 4 Steps
Soku AI decides what to say and where to run it. ElevenLabs performs it. Together they close the audio production loop.
Soku Writes the Brief
Soku AI produces the concept, hook, and script for an angle worth testing, based on your account data and competitor creative signals.
ElevenLabs Performs It
Pick, clone, or design the voice, direct the read with inline audio tags, and export every market variant you need from the same script.
Soku Deploys and Measures
The audio becomes ad variants across placements and goes live on Meta, Google, and TikTok, with performance tracked per creative.
Insights Loop Back
Soku shows which voice, energy, and pace converted — so the next batch is voiced by what already worked rather than by what sounded good in the room.
Built for Video Ad Teams
Voice A/B Testing
Run the same cut with six different voices and let CPA pick the winner. The one the brand team preferred in the room frequently loses.
Multi-Market Localization
Enter a new market with a native-sounding read rather than subtitles, generated from the script you already have.
Faceless UGC and Explainers
Narrate screen recordings, product walkthroughs, and faceless short-form without booking talent or recording a take.
Rapid Script Iteration
Change a line, regenerate the read, and ship the revision the same hour — instead of paying a pickup session fee.
Dubbing Proven Winners
Take a creative that already works in one market and translate it while keeping the original speaker's voice.
Conversational Ad Formats
Use the Text to Dialogue API for two-speaker testimonial and interview formats that read as genuinely conversational.
What Soku Adds
ElevenLabs solves generation. Soku solves everything between a finished audio file and a conclusion about what to make next.
Per-variant performance data
Soku tracks CTR, CPA, and ROAS by creative variant, so voice choice becomes a measured decision rather than a taste one.
Without this layer, a six-way voice test produces six files and no answer.
Deployment across every channel
Push finished creative live to Meta, Google, and TikTok from one place, in the right aspect ratio for each placement.
One read, regenerated into the full placement set rather than exported five times by hand.
Briefs informed by your account
Soku reads your ad accounts and competitor creative signals to decide which angle is worth voicing in the first place.
The cheapest voiceover in the world does not help if the script is testing the wrong idea.
Pricing
ElevenLabs prices on monthly credits. The detail that catches teams out: the free tier has no commercial license, so any ad use starts at Starter.

ElevenLabs and Soku AI FAQ
Does Soku AI connect to ElevenLabs through an API?
No. This is a workflow pairing rather than a live data sync — you generate the audio in ElevenLabs and bring the file into Soku, the same way most creative tools sit next to a media-buying platform. Soku handles the variants, the deployment, and the performance measurement around it.
Can I use ElevenLabs voiceover in paid ads?
Yes, but not on the free tier. The free plan's 10,000 monthly credits do not include a commercial license. Commercial use begins on the Starter plan at 5 USD per month, which also unlocks Instant Voice Cloning and Dubbing Studio.
How many languages does ElevenLabs support?
Eleven v3 supports 70+ languages, and the same voice identity carries across them. For advertising that means a single script can produce native-sounding reads for every market rather than requiring a casting call per locale.
What are audio tags and why do they matter for ads?
Audio tags are inline directions such as [whispers] or [excited] written straight into the script, which Eleven v3 performs. For ad testing they matter because read energy becomes a one-line change — you can test calm against urgent on the same script without re-booking anything.
Is voice cloning safe to use for a brand?
It carries real consent and disclosure obligations. Clone only voices you have written permission to use, and check the advertising policies of the channels you are running on. If you want a distinctive voice without the rights question, Voice Design generates an entirely synthetic one from a text prompt with no source recording.
Which voice should I use for my ads?
Test it rather than choosing it. Voice identity — gender, age, accent — moves performance more than most teams expect, and the winner is frequently not the one preferred in the room. Run the same cut with several voices and let CPA decide, which is exactly the loop Soku closes.
Can ElevenLabs dub a video ad that already works?
Yes. Dubbing Studio translates existing video while preserving the original speaker's voice, so a proven creative can enter a new market without a reshoot. Then run it through Soku to deploy and measure it against the original.
