Feature-by-Feature
Pricing model
Silenis is pure pay-per-use at $0.12 per 6 seconds of source video (roughly $1.20 per minute). You upload a video, get a free watermarked preview, and pay only when you download the unwatermarked file. There is no subscription, no monthly minimum, and no credits that expire.
Wavel.ai uses credit-based monthly and annual subscriptions. Free is $0/month with 15 one-time credits (enough for about 5 minutes of dubbing, with watermarking and no downloads). Basic is $25/month or $16/month billed annually ($192/year) for 100 credits/month. Pro is $40/month or $26/month annually ($312/year) for 300 credits/month. Scale is $100/month or $66/month annually ($792/year) for 1,000 credits/month. On every plan, 3 credits = 1 minute of dubbing, 1 credit = 1 minute of subtitles, 1 credit = 1 minute of text-to-speech. Annual plans save roughly 33% versus monthly. Credits roll over every month on paid plans. Wavel also offers enterprise pricing for higher volume and custom needs.
Music and sound effects
This is the biggest practical difference between the two tools. Silenis uses Demucs-based vocal separation to isolate the spoken voice from the rest of the audio, runs translation and synthesis on the vocals only, and then remixes the new voice over the original background music, sound effects, and ambient sound. If your source video has a music track or environmental audio, that audio is preserved in the dub.
Wavel.ai focuses on the spoken track and a clean editing experience. It ships a multilingual subtitle editor, voice changer, and several video tools, but the original background music in a source video is not the centerpiece of Wavel\u2019s pitch. If you need a source-video music bed to survive the dub, Wavel is not the right tool for that job.
Voice cloning
Wavel.ai ships voice cloning on every paid tier — 10 voice clones on Basic, 30 on Pro, 100 on Scale. Wavel also offers AI Twins, a personal avatar feature, on Basic and Pro. This is genuinely useful for branded content where a specific voice identity matters and you have the rights to clone it.
Silenis deliberately does not require voice cloning. It uses a curated voice catalog and matches voices by attributes like tone, pace, and language. This keeps the workflow fast (no reference audio to upload) and avoids the ethical and legal complications of cloning someone's voice without their explicit consent.
Languages and voices
Wavel.ai advertises 40+ languages for dubbing, voice generation, captions, and speech synthesis, and ships a library of 250+ AI voices that vary by age, gender, tone, and dialect. The breadth of the voice catalog is one of Wavel's real strengths. If you need a specific voice personality (warm, energetic, calm, authoritative) and you are willing to audition a few to find the right one, Wavel gives you a lot of room.
Silenis currently supports 40+ dubbing languages and focuses on shipping high-quality TTS voices in the languages it does support. The catalog is built around the dubbing pipeline rather than a separate voice marketplace. Raw count is similar; the practical difference is in which languages have the strongest TTS voice quality, which varies language by language and changes as the catalogs evolve.
Product scope
Wavel.ai is a much broader platform than Silenis. Beyond dubbing, it ships a multilingual subtitle editor, a transcription tool, a voice changer, a sound effects generator, an AI video generator (with multiple models including a cinematic Kling 2.6 path and a MultiModal V3 multi-scene path), text-to-video, PPT-to-video, AI Twins, voice cloning, and accent generation. If you want one subscription that covers dubbing plus a wide range of voice and video tools, Wavel is the more feature-complete choice.
Silenis is a focused dubbing tool: upload, preview, pay, download. There is no video generator, no avatar system, and no broader voice marketplace. The benefit of being focused is that the dubbing pipeline itself — music preservation, emotion/prosody, context-aware translation, lip-accurate timing — gets the team's full attention.
Lip-sync
Wavel.ai offers lip-sync as an add-on on Basic and Pro, which adjusts the speaker's mouth movements to match the dubbed audio. This is valuable for talking-head content. Silenis does not currently offer lip-sync; it targets the dubbing audio layer (replacing the audio track) rather than visual re-animation.
API access
Wavel.ai publishes developer API documentation for integrating TTS, dubbing, transcription, and other tools into your own product or workflow. Silenis does not currently expose a public API. If programmatic integration is a requirement, Wavel is the more practical choice today.
Pricing Comparison
The clearest way to compare is by the dollar cost for a specific job. Take a 10-minute video dubbed into Spanish:
- Silenis: 600 seconds × ($0.12 / 6) = $12.00. No subscription, pay once.
- Wavel.ai Free: 15 one-time credits cover about 5 minutes. The 10-minute job exceeds the free tier, so a paid plan is required.
- Wavel.ai Basic (annual, $192/year): 10 minutes = 30 credits. The plan includes 100 credits/month, so the job fits, but the annual subscription cost ($192) is the real number — not the implied per-minute rate of $0.48.
- Wavel.ai Pro (annual, $312/year): Same 30 credits, same job fits easily in the 300-credit monthly allowance, with 270 credits left for other work that month.
For a one-off 10-minute job, Silenis at $12 is significantly cheaper and simpler. For someone using Wavel monthly for dubbing plus the other tools in the suite (subtitles, TTS, video), Wavel Pro annual at $26/month can be a good value — but the question is whether you need the rest of the Wavel suite, not just the dubbing.

FAQ
Is Silenis cheaper than Wavel.ai?
For pure dubbing, yes, especially for low-volume users. Silenis is $0.12 per 6 seconds of source video (about $1.20 per minute) with no subscription at all. Wavel.ai charges 3 credits per minute of dubbing. On Basic ($25/month or $16/month annual), 100 credits/month = 33 minutes/month, so the implied per-minute cost is $0.75/month-billed or $0.48/annual-billed. On Pro ($40/month or $26/month annual), 300 credits/month = 100 minutes/month, so the implied cost is $0.40/month-billed or $0.26/annual-billed. Wavel becomes cheaper per minute on higher annual tiers; Silenis is cheaper and simpler for one-offs because there is no subscription to commit to.
Does Wavel.ai preserve background music in the dub?
Wavel.ai focuses on replacing the spoken track with the dubbed voice and ships a clean editor for adjusting scripts and timing. It is not specifically designed around music preservation. If your source video has a music bed, the original music is not the centerpiece of Wavel’s pitch. Silenis uses Demucs-based vocal separation to isolate the spoken voice, translate and re-synthesize it, and remix it with the original background music and sound effects, so the original music survives the dub. If keeping the original music intact is a requirement, Silenis is purpose-built for that.
Does Wavel.ai support voice cloning?
Yes. Wavel.ai offers voice cloning on every paid plan: 10 voice clones on Basic, 30 on Pro, and 100 on Scale. Wavel also ships AI Twins, which is a personal avatar feature, on Basic and Pro. Silenis deliberately does not require voice cloning — it uses a curated voice catalog matched by tone and pace. If you need a specific real person’s voice and have the rights to clone it, Wavel is the more capable option. If you just need natural voices without uploading reference audio, Silenis is faster and sidesteps the consent question.
How many languages do they support?
Wavel.ai advertises 40+ languages for dubbing and subtitles, with a library of 250+ AI voices across age, gender, tone, and dialect. Silenis currently supports 40+ dubbing languages. The headline number is similar; the practical difference is in which languages have the strongest TTS voice quality, which varies language by language and changes over time. Both cover the major global languages; Wavel’s voice catalog breadth is a real strength.
Does Silenis have a free preview?
Yes. You can upload any video to Silenis and get a free watermarked preview before paying anything. You only pay when you decide to download the unwatermarked file. Wavel.ai offers a Free tier at $0/month that includes 15 credits one-time (about 5 minutes of dubbing at 3 credits/min) with watermarking, no downloads, no credit top-up, and a 7-day trial of all tools. Wavel’s free tier is a useful way to evaluate the platform, but it is not enough to dub and download a full video without paying.
Which is better for a one-off dubbing job?
Silenis. Pay-per-use with a free preview, no subscription, and music preservation built in. A 5-minute one-off dub on Silenis costs $6. The equivalent on Wavel Basic at 3 credits/min would consume 15 credits — exactly what the Free tier provides, but with watermarking and no downloads. To actually download a one-off 5-minute dub from Wavel without a watermark, you would need a paid subscription, which is overkill for a single project.
Which has better voice quality?
Wavel.ai has a deep TTS voice library with 250+ voices and a polished voice-cloning workflow. Silenis uses Fish.audio for synthesis, which delivers natural-sounding voices in the supported languages and focuses on the dubbing pipeline integration. Both are credible. Wavel’s strength is the breadth of its voice catalog; Silenis’s strength is the integration of emotion/prosody preservation with the dubbing pipeline. The right answer depends on whether you care more about voice variety (Wavel) or about the end-to-end dubbing output with music and emotion intact (Silenis).
