Speechlab.ai︎︎︎ is a generative AI platform for speech-to-speech translation that captures thought and emotion with the versatility of human voice. Its mission is to make the world more accessible by bridging language barriers.

I joined Speechlab in 2023 as the founding designer and led the end-to-end design and launch of the company’s first product, Speechlab Dubbing︎︎︎, taking it from MVP to production. Since its initial launch in late 2023, Speechlab Dubbing has gained strong traction among enterprise customers across media and education, as well as global language service providers. In parallel, we are bringing our generative speech and voice synthesis technology into a new real-time product, Speechlab Live︎︎︎.

Case studies available upon request.

Translate. Select a target language. AI translates the spoken content segment by segment. Edit every line.

Caption/Subtitle. Create captions or subtitles from the transcript/translation. Frame-accurate, validated, broadcast-ready.

Generate dub.  Assign a voice per speaker then render the dubbed audio. Preview in the editor alongside the source.

I also led the redesign of the landing page for the company’s website and successfully boosted the sign-up conversion rates with stronger product adoption.
