Unmixr Dubbing

Unmixr Dubbing is an AI dubbing tool for translating spoken audio and video into new voice tracks. It is best suited to creators and teams who want to revise translations and control voices by speaker. Its segment-level editing is a strong fit for localization work that needs correction, but not for videos that require lip-synced speech.

Overview

Unmixr combines speech transcription, translation, and AI voice generation in a workflow with review before dubbing. Users can edit translated lines, split or merge segments, and regenerate only the parts they change. That targeted control can save rework when a few lines need correction, though it makes human review part of the process rather than promising a finished result in one pass.

The system detects speakers and allows a distinct voice for each, helping keep dialogue differentiated. Users can adjust timing and speaking speed per segment, and exports include dubbed video or audio plus translated subtitles in SRT and VTT formats. Uploads can be up to 60 minutes; common formats include MP4, MOV, MP3, and WAV. Unmixr does not re-animate lips or change video frames, so it cannot deliver visual lip synchronization.

Key features

• Translation control: Edit lines, split or merge segments, and regenerate changed sections. This is useful for correcting localized dialogue without rerunning the entire piece.
• Speaker-specific voices: Assign separate AI voices to detected speakers, a practical advantage for interviews and dialogue with multiple participants.
• Segment timing: Adjust timing and speaking speed section by section to better align the dub with the video. It offers control over pacing, but does not make the speakers’ mouths match the new audio.
• Subtitles and media exports: Export dubbed video or audio and subtitles in SRT or VTT, giving users both a replacement voice track and subtitle files.
• Privacy and support: Unmixr says it uses TLS encryption, hashed password storage, access controls, and production-system isolation. It also says user content and voice data are not used to train AI models. Support is offered by email and Discord, with a stated aim to respond within 24 hours on business days.

Language coverage has a discrepancy: the dubbing page says more than 100 languages, while paid plan summaries specify 85 output languages. Buyers who need a particular language should confirm coverage before committing.

Pricing

Unmixr uses a freemium model. The free account provides 5,000 credits on signup and supports dubbing, but exports are limited to three minutes and carry a watermark. It has no trial. That is enough to assess a short clip, not to produce clean, longer-form deliverables.

Lite costs $9 a month, billed at $9 /mo or $90/year. It includes 100K credits per month, dubbing, and 85 languages, but no developer API. It is the lowest-cost paid option for users who need more than the free export allows and do not need API access.

Starter costs $19 a month, billed at $19 /mo or $190/year. It includes 500K credits per month, dubbing, 260 minutes listed, 85 languages, and a seven-day trial. Developer API access begins at this tier, with tiered rate limits, making it the entry point for API workflows.

Pro costs $49 a month, billed at $49 /mo or $490/year. Its 2.6M monthly credits and 1,354 minutes listed come with dubbing, 85 languages, and higher API limits. Business costs $99 a month, billed at $99 /mo or $990/year, for 6.5M credits, 3,385 minutes listed, the highest API limits, and priority support. These higher tiers suit heavier workloads; Business is the clearest fit when priority support matters.

The seven-day trial includes 20,000 credits. Background music separation is available on paid recurring plans, but not during the trial. The plan page also lists API access on Starter, Pro, and Business, despite the separate platform entry identifying API as a platform; Lite explicitly has no developer API.

Platforms

Unmixr is available on the web. API access is included with Starter, Pro, and Business plans, subject to tiered rate limits; Lite does not include it. The entry also identifies API as a platform, but this is not the same as access on every plan.

Who it's for

Unmixr is a sensible choice for creators, publishers, and teams adapting interviews or other spoken video and audio who want per-speaker voices, editable translations, subtitles, and segment-level timing control. It is less suitable when lip synchronization is essential, or when a free, watermark-free export is needed. The free cap is especially restrictive for work longer than three minutes.

Pros and cons

• Pros: Segment-level edits and regeneration let users fix specific translation or timing problems without redoing the whole dub.
• Pros: Distinct voices for detected speakers help preserve dialogue distinctions, while SRT and VTT exports support subtitle workflows.
• Pros: The free account enables dubbing, and paid plans scale from 100K to 6.5M monthly credits.
• Cons: Dubbing does not synchronize visible mouth movements with the translated speech, limiting its fit for close-up dialogue.
• Cons: Free exports stop at three minutes and are watermarked, so a usable longer deliverable requires a paid plan.
• Cons: Lite has no API access, and the stated language count differs between the dubbing page and paid plan summaries.

Alternatives

AI Dubbing Software and Text-to-Speech Software are category directories for comparing options by use case.

• HeyGen is worth considering for a free plan that allows up to three videos per month, each up to one minute, and is available on Android and iOS as well as web and API.
• pyVideoTrans is an open-source option with no feature limits and support for desktop, self-hosted, and web platforms; third-party API charges are paid separately.
• VideoLingo offers a free 15 minutes of video translation for English and Chinese videos, with bilingual subtitles and 480p output.
• CAMB.AI offers a one-time free 5K-credit plan and a paid Essentials plan at $5 a month with 10K credits per month.
• Perso Dubbing provides one free generation on signup, including dubbing, speech-to-text, and audio separation.
• Vidby offers a free plan with 30 credits, 70 languages, watermarked output, original and subtitle downloads, and automatic voice cloning.
• Vozo AI may suit a creator who wants a project-based free tier: it includes three projects, 20 AI points, about six AI dubbing minutes, one seat, and one concurrent task.
• DubDuck provides $10 in free credits for each new account; free dubbed videos are watermarked, and beta uploads are limited to 3.5 minutes and 50 MB.

Verdict

Choose Unmixr Dubbing if you need speaker-specific AI voices and the ability to correct translations and timing one segment at a time. Its strongest case is controlled localization with subtitle exports, backed by paid tiers that add substantial monthly credit allowances and API access. Look elsewhere if lip-synced visuals are a requirement or if the three-minute, watermarked free export is not enough to judge your intended workflow.
