Why Translate English Content to Welsh?

The ability to translate English video content to Welsh has become essential in our interconnected world. Whether you're a business expanding into Welsh-speaking markets, an educator creating multilingual learning materials, or a content creator building a global audience, English-to-Welsh translation bridges the gap between your message and millions of potential viewers who prefer content in Welsh.

Professional English-to-Welsh translation traditionally required expensive human translators, often costing hundreds of dollars per hour of content. The process was slow, sometimes taking weeks to complete a single project. Sonix revolutionizes this workflow by combining advanced English speech recognition with sophisticated Welsh translation algorithms, delivering results in minutes rather than days while maintaining professional-grade quality.

How English-to-Welsh Translation Works

The Sonix English-to-Welsh translation process begins with our industry-leading speech recognition technology. When you upload your English video file, our AI models—trained on millions of hours of English audio—accurately transcribe every word, capturing nuances like speaker identification, punctuation, and timing. This English transcript forms the foundation for high-quality Welsh translation.

Once transcription is complete, our neural machine translation engine converts the English text to Welsh. Unlike basic word-for-word translation, our system understands context, idioms, and cultural expressions, producing Welsh subtitles that read naturally to native speakers. The translation preserves the original timing and speaker labels, ensuring perfect synchronization with your video content.

Editing and Refining Your Welsh Translation

Sonix provides a powerful side-by-side editor where you can view your original English transcript alongside the Welsh translation. This makes it easy to verify accuracy, adjust phrasing for your specific audience, and ensure technical terms or brand names are handled correctly. You can click any segment to hear the corresponding audio, making the review process intuitive and efficient.

For specialized content—legal proceedings, medical discussions, or technical tutorials—the editor lets you fine-tune translations to match industry-specific terminology. You can also adjust subtitle timing, merge or split segments, and customize caption styling before export. The result is a polished Welsh version of your English content ready for distribution.

Export Options for Welsh Subtitles

Once your English-to-Welsh translation is complete, Sonix offers flexible export options to fit any workflow. Download Welsh subtitles as SRT or VTT files for YouTube, Vimeo, or social media platforms. Export to Word or PDF for documentation purposes. Or use our burn-in feature to permanently embed Welsh captions into your video file, ensuring they display correctly on any device or platform without requiring viewer settings.
