Launching your app or product in new markets requires clear audio in the local language. I provide synchronized AI voiceovers for explainer videos and product demos in multiple languages, ensuring technical terms are pronounced correctly and the tone matches your brand’s global image. This is a practical solution for SaaS companies, tech startups and hardware manufacturers who need to localize their marketing videos efficiently and cost-effectively.

You supply the original video file and the translated scripts. I handle the rest: selecting culturally appropriate AI voices for each target language, generating the audio with correct timing and intonation for a demo, and meticulously syncing the new voiceover to the existing video’s on-screen actions and text animations. The final delivery includes the complete video as an MP4 with the new integrated audio track, the audio alone as an M4A file and separate audio tracks for background music and sound effects if you need to adjust levels later.

I work with a verified set of AI voices across more than fifteen languages, including Spanish, French, German, Portuguese, Japanese and Korean. For each, I understand the typical pacing and formalities of commercial narration in that region. The challenge isn’t just translation, it’s adaptation – making sure the enthusiastic tone of your English demo doesn’t become overly casual in Japanese, for example. I adjust the speech rate and energy to suit regional expectations, based on my experience localizing content for clients entering European and Asian markets.

This service works for teams that have already invested in a high-quality master explainer video and need to maximize its return. It’s far faster and more consistent than coordinating multiple human voice talent sessions in different time zones. I also provide a quality check against the original video to ensure key features are highlighted at the right moment by the voiceover. You get a set of market-ready videos that maintain your product’s professional presentation worldwide, helping you scale your marketing efforts without rebuilding assets from scratch.
