In our digital era, one of the best ways to reach a wider audience and grow your business is to embrace multilingualism. SEO statistics reveal that multilingual websites can reach 75% more internet users whose primary language is not English, and 60% of global consumers prefer to browse sites in their native language.
These statistics reveal just how powerful multilingualism can be as a business strategy. But what are you supposed to do if you and your team only speak one language? Inaccurate translations and badly dubbed videos certainly won’t help your brand. That’s where a top-rated lip sync video API can help.
What is a Lip Sync Video API?
AI technology has made video translation far more accessible, but when you’re investing in multilingual content, you want the final product to seem as natural and realistic as your original content.
Lip sync technology can make that happen. AI-powered lip sync synchronizes your translated audio with the lip movements of the person or avatar in your video. By matching audio and lip movements, you can avoid that “bad dubbing” effect and create a natural viewing experience.
But what is an API? Application programming interfaces (APIs) are collections of tools, guidelines, and protocols that facilitate communication between different types of software. Essentially, lip sync APIs allow developers to integrate the lip sync AI technology from one software platform into their own platforms or apps without having to create complex codes to integrate them.
How do Lip Sync Video APIs Work?
Lip sync video APIs utilize facial recognition algorithms and machine learning to understand lip movements and match them to translated audio.
With Tavus’ lip sync and dubbing APIs, you have two options for matching audio and video lip movements: In place lip sync and dubbing. In place lip sync allows you to watch your video and identify segments where the audio needs to be changed to match the lip movements. With dubbing, you can simply upload your video, choose a new target language, and let Tavus provide you with a dubbed video (via voice cloning), including lip movements to match the new voice!
Lip Sync Video API vs Traditional Lip Syncing
Traditional lip syncing, or manual synchronization, requires manual adjustment of lip movement timing to match your audio track. Editors who do manual sync need skilled attention to detail, and the process takes a significant amount of both time and effort.
Lip sync video APIs utilize auto synchronization, which involves software that relies on AI tools to analyze the audio track and generate lip movements to match. APIs like Tavus can work faster and do the job for you, saving you time and money.
