Speax

Speax works from your video files: you upload a clip, pick the languages you want, and download a dubbed version with lip-sync applied.

Speax is an AI video dubbing platform that translates spoken audio into other languages and replaces it with natural-sounding AI voices, made for people who want to reach viewers outside their home market.

The workflow centers on three actions, uploading, managing and downloading videos, so finished dubs stay in a single place instead of scattered across folders.

Batch processing means you can queue several videos rather than run them one by one, which matters if you publish regularly or have a back catalog to localize.

Speax also lists voiceovers, AI voice cloning, transcription and video translation among its capabilities, so it covers the steps that usually sit between a source recording and a translated one.

The lip-sync is the feature to test first.

Dubbing is easy to do badly, and matching mouth movement to a new language is where results vary most, so run a short sample of your own footage before committing a larger project.
