Generative AI for Media Content: Generative AI (GAI) systems have the capacity to generate new material autonomously, including text, images, audio, or video.[3]
An AI video dubbing app like Smartcat uses AI and voice technology to replace the original audio in videos with translated speech in different languages. Smartcat's solution combines automatic transcription, translation, and neural voice synthesis to create natural-soundingdubbed videos quickly and affordably.
AI voice refers to synthetic speech generated by artificial intelligence (AI) systems. They can replicate human-like voices over a wide range of applications. These voices are created using sophisticated algorithms that mimic the nuances of natural human speech, such as tone, pitch and cadence.[1]
AI voice translation works by first transcribing the original audio, then translating the text into target languages, and finally using text-to-speech dubbing to generate synthetic voices that match the original tone and timing.
You can also preview all of the voices before applying it across your video. If you change your mind, you can also switch to another voice at any point. By editing the subtitles, you will also change what the AI voice over is saying.
The Smartcat Media Agent can apply an AI voiceover to your video. You can choose from 30+ different voice options in many different languages and dialects.
Smartcat enhances this process with human-in-the-loop quality checks to ensure accuracy. You can invite as many collaborators as needed into the platform to edit the video subtitles or dubbing for you. You can also hire professional reviewers within the Smartcat platform via SmartcatMarketplace— one of the world’s largest networks of vetted experts (500,000+).
