An open-source app developed by Sync Labs and set to launch in February 2024 aims to revolutionize AI translation, dubbing, and lip-synching by seamlessly integrating speech-to-text, text-to-speech, and voice cloning technologies. The app's backbone utilizes the Gladia API for speech-to-text and translation, ElevenLabs for text-to-speech and voice cloning, and Sync Labs for visual dubbing, offering hyper-realistic voiceovers and matching lip movements in translated videos. Speech-to-text involves converting spoken words into text through preprocessing, speech recognition algorithms, and language modeling, while text-to-speech reverses this by analyzing text with natural language processing and prosody modeling to create expressive synthesized speech. Voice cloning enhances this process by mimicking a target voice's unique characteristics using deep neural networks, and visual dubbing aligns these elements with realistic lip movements, providing a powerful tool for breaking language barriers in video content.
