EarDub

EarDub is a dubbing extension for YouTube specifically designed for Chromium-based browsers, such as Chrome and Microsoft Edge. Its primary function is to automatically translate and dub videos in real time using AI voices. Unlike conventional subtitle translators, this tool allows users to listen to content in their own language while maintaining visual synchronization with the speaker, eliminating the need to read on-screen text while viewing content on a computer.

The technology behind EarDub is based on context-aware AI translation. Instead of translating isolated fragments or single words, the system groups subtitles into complete sentences before processing them, ensuring more natural, fluid, and coherent narration. The software employs a phrase-level synchronization approach, dynamically adjusting the speech rate (up to a maximum of 1.45x) so that the generated voice matches the rhythm of the original video. Additionally, for content that lacks original subtitles, the tool has the capability to perform advanced speech recognition to generate dubbing directly from the source audio.

EarDub’s catalog is extensive, offering support for 75 languages and more than 300 AI voices with different tones, genders, and regional accents. Its key functional capabilities and practical benefits include:

• Real-time dubbing: It works instantly upon pressing the play button, with no wait times or file uploads required.
• Dual audio control: It allows you to mix the volume of the original and dubbed voices using independent controls, which is useful for maintaining the video's ambient tone.
• Bilingual subtitles: It offers the option to display translated and original subtitles simultaneously, with adjustable sizes from 14 to 28 px.
• Multi-platform compatibility: In addition to YouTube, it works on learning sites like Udemy and Coursera, as well as social media networks like X (Twitter) and Bilibili.

This solution is ideal for users who consume programming tutorials, financial investment courses, or academic lectures in foreign languages. By allowing users to keep their eyes fixed on the code, charts, or presentations, EarDub optimizes learning and productivity. It is also an effective tool for consuming long-form podcasts and entertainment content, allowing for clear audio listening while multitasking on a mobile device (via the Vivaldi browser on Android) or a desktop computer. Setup is simple, requiring just a couple of clicks to activate dubbing on any compatible video.
