Frequently Asked Questions about Dubbing
Kapwing has revolutionised the video dubbing process with its innovative AI-powered technology. The platform combines several advanced AI technologies to create natural, localised dubbed videos. Here's a breakdown of how each component works:
Transcription
Kapwing uses Automatic Speech Recognition (ASR) technology to extract spoken dialogue from the video audio. It separates clean speech from background sounds such as music, laughter, and sound effects, improving transcription accuracy and the naturalness of the final dub.
Translation
The extracted text captions are translated into the target language using machine translation from various providers. Kapwing also supports user-uploaded glossaries or translation rules for domain-specific vocabulary, ensuring better translation consistency. Embedded text layers in the video are automatically detected, translated, and overlaid to maintain all visible text in the localised language.
Synthetic Voice Generation
Kapwing leverages premium text-to-speech (TTS) providers to create highly realistic synthetic voices in over 40 languages. For Business and Enterprise customers, the system can clone the original speaker’s voice to produce a more authentic dub. It also detects speaker changes in videos with multiple speakers to assign different synthetic voices accordingly.
Timing Adjustment
Generative AI is used to align the new dubbed audio timing with the original video, making sure the translated speech matches the video’s pacing. This includes advanced timing and speed adjustments to synchronise dubbed audio closely with the original scenes.
Lip Syncing
Kapwing can generate a new video layer where the speaker’s lip movements are modified to match the dubbed synthetic voice. This lip sync feature creates a natural visual sync between the new audio and the speaker’s mouth movements in the video.
Additional features include support for multilingual dubbing workflows, caption editing, support for RTL languages and complex scripts, real-time team collaboration, and extensive file upload and export options.
In summary, Kapwing combines speech-to-text transcription, machine translation, tailored synthetic voice generation with voice cloning, AI-powered timing synchronisation, and lip synchronisation to deliver a comprehensive AI dubbing solution that preserves audio naturalness and visual coherence in localised videos.
Kapwing is an integrated video and audio editing platform, offering tutorials on using the latest features through its Release Notes. The dubbing tool is free to try, with a limit of 8 minutes for free users. To access Lip Sync for dubbing, users need to upgrade to Kapwing Pro or Business, which are billed per-seat.
The dubbing tool on Kapwing is utilised by various entities such as multinational companies, universities, churches, and government agencies. You can choose to keep or delete the background audio from your project on Kapwing, with the background audio automatically added to the dubbed video by default.
Any changes made to the transcription or original language of a dubbed video will consume translation minutes based on the duration of the edited section. Regenerating a section of a dubbed video will consume text-to-speech minutes based on the length of that section.
Kapwing does not provide information about which companies use their dubbing service. However, notable users of Kapwing include Chevrolet, SHEIN, OEC, Pilatesology, and Hollister.
