Speechlab

Speechlab is an AI-powered localization and dubbing platform designed for video and audio content. It combines transcription, translation, captioning, subtitling, and dubbing into one unified editor, allowing users to move from raw media to fully localized output without switching between tools. The platform supports more than 50 languages and is aimed at media publishers, marketing teams, corporate learning and development departments, and localization service providers. The product is built around spoken content such as documentaries, podcasts, YouTube videos, audiobooks, product demos, and training modules. Users can start with transcription and then translate, caption, subtitle, or dub as needed. A waveform timeline editor enables segment-level review and correction, while source-clone mode can preserve a speaker's voice characteristics in another language. For multi-speaker content, each speaker can be cloned independently, making it suitable for interviews, panel discussions, and narrative media. Speechlab uses transparent per-minute credit pricing and includes a free tier with two projects. Pro plans add unlimited media length, 4K resolution, sharing for review, and API access. Enterprise plans include bulk processing, API integration, human linguist review, custom voices, role-based access, white-label options, and invoice billing. The platform is designed for teams that need quality control, collaboration, and integration into existing media or translation pipelines.
