What is Perso AI?
Perso AI is a dubbing AI platform that translates and dubs video and audio content into 33+ languages. It processes any uploaded video or audio file and outputs a dubbed version with the original speaker’s voice preserved through AI voice cloning. The platform also generates synchronized lip movements and subtitles in the target language. It covers the full localization pipeline in one tool, from transcription and translation to voice synthesis and lip sync. Content creators can submit a URL directly instead of uploading a file. An API is available for developers and enterprise teams who need to integrate dubbing AI into existing workflows.

Real-World Applications
Video creators publishing on platforms like YouTube or TikTok may use dubbing AI to reach audiences in Spanish, Portuguese, Korean, Hindi, or other languages without re-recording content. A travel vlog or product review recorded in English can get a fully dubbed, lip-synced version in multiple languages from a single upload. This makes multilingual publishing practical at the pace most content workflows demand.
Course creators and training teams with large libraries of instructional video may find dubbing AI useful for localizing content without re-shooting or hiring voice talent for each target language. A 500-hour course library can move into new markets with translated audio and matching lip sync, with the script editor available to correct any terminology the AI mishandles.
Marketing agencies producing video ads or brand content for international campaigns can use dubbing AI to produce localized versions of the same asset. Product demo videos, awareness campaigns, and social content can go through the platform and come out in the required languages with consistent voice identity across markets, reducing the need for separate production runs per region.
Enterprise teams managing internal communications, compliance training, or customer-facing video content across multiple countries may use dubbing AI to maintain consistent messaging without rebuilding assets for each locale. The multi-speaker capability, team collaboration tools, and API access support higher-volume production at the organizational level.
