Can I use Sarvam voiceovers in commercial ads?

Yes. All audio generated through Sarvam is licensed for commercial use: Facebook ads, Instagram Reels, YouTube ads, radio spots, audio streaming ads, in-store announcements. No per-impression charges, no royalty fees. You pay only at generation time.

How much does it cost to test 20 ad variants?

A 30-second ad is about 500 characters. At Rs 30 per 10,000 characters, that costs under Rs 2 per variant. Twenty variants cost under Rs 40 total.

Does the audio quality work for Instagram Reels and YouTube Shorts?

Yes. Sarvam outputs 24kHz audio, which exceeds the quality requirements for all social media platforms. The audio is clean enough for mixing with background music and sound effects in CapCut, Premiere Pro, or any editor.

Can I A/B test different voice styles?

Yes. Generate the same script with a warm female voice, an energetic male voice, and an authoritative voice in seconds. Upload all three as separate ad variants in Meta Ads Manager. Let the platform optimize for whichever voice drives more clicks.

How do I create the same ad in multiple Indian languages?

Translate your winning script into target languages (use Sarvam Translate or any tool), then generate voiceover in each language. One Hindi ad becomes Tamil, Telugu, Bengali, Marathi, Gujarati, Kannada, Malayalam, Punjabi, Odia, and Assamese variants in minutes.

What about brand name pronunciation?

Sarvam’s preprocessing handles brand names, product names, prices, and common abbreviations naturally in all 11 Indian languages. For specialized terms, the API ensures numbers, currency amounts, and technical terms are spoken correctly.

Voiceover needs to move at performance marketing speed

Speed

Ad iteration stalls when voiceover takes 48 hours

Your ad manager shows Hook A beating Hook B. You want to test Hook C with a different tone. Traditional recording means a 48-hour wait. Sarvam generates that variant in 5 seconds. Faster iteration means faster wins.

Volume

50 UGC ads per month need voiceover at content speed

D2C brands ship 50 to 100 UGC video ads per month. Each variant needs a slightly different script, hook, or CTA. Recording that many voiceovers manually is not sustainable. Type, generate, drop onto footage, ship.

Languages

One winning script scales to 11 language markets

A campaign performing in Hindi markets needs Tamil, Telugu, and Bengali variants to scale nationally. That means new voiceover in each language. Sarvam lets you translate the script and generate all 4 in 2 minutes.

From script variant to live ad in minutes

Write variants, not scripts

Start with one base script. Create 10 variants by swapping the hook, the offer, or the CTA. Keep the structure, change one element per variant. 10 variants from one base script takes 15 minutes of writing.

Pick a voice that fits the ad format

Energetic voice for a Reels hook. Warm voice for a testimonial-style ad. Authoritative voice for a product comparison. Test multiple voices on the same script to see which performs. Each generation takes 5 seconds.

Generate, listen, ship

Generate all variants. Listen to each (takes seconds, not minutes). Drop the audio onto your video footage in CapCut or Premiere. Push to Meta Ads Manager, Google Ads, or your DSP. Total time from script to live ad: under 30 minutes.

Scale to regional markets

Winning script in Hindi? Translate to Tamil, Telugu, Bengali, Marathi. Generate regional variants in seconds. Run region-specific campaigns across 11 language markets from one creative brief.

Where AI ad voiceover fits

UGC video ads

Product footage with voiceover is the dominant ad format on Instagram and YouTube. D2C brands ship dozens per week. Sarvam’s conversational voices sound casual and authentic, matching the UGC format.

Regional radio and audio campaigns

FM radio remains India’s most cost-effective regional advertising channel. A local retailer or hospital needs a Tamil or Gujarati radio spot by tomorrow. Script it, generate audio, deliver to the station.

Audio ads on streaming platforms

Spotify and JioSaavn serve 15 to 30 second audio ads between songs. Sarvam makes it practical to create language-specific versions for every target market in minutes.

In-store and announcement systems

Retail chains, malls, and transit hubs run voice announcements in multiple languages. Seasonal promotions and safety messages all need multi-language audio. Update by changing the text, not re-recording.

From one perfect ad to twenty good tests

Volume over perfection

Traditional advertising optimized for one perfect creative. Hire a voice artist, record in a studio, mix with music, run the campaign. Performance marketing works differently. It optimizes through volume and iteration. The winning ad is discovered through testing, not predicted through intuition. The team that tests 20 script variants finds the winner faster than the team that perfects one.

The voice bottleneck

Voice has been the bottleneck in this iteration loop. You can write 20 headline variants in an hour. You can swap product images in minutes. But getting 20 different voiceovers meant 20 separate recordings. With Sarvam, voiceover becomes as fast as every other part of the creative process. Write, generate, test, iterate.
