Speaker-aware
Dialogue segments are grouped by speaker so each person can keep a consistent vocal identity.
Experimental local video dubbing
Keep the picture.
Give the dialogue another language.
Speakintosh analyzes dialogue with a local Whisper Turbo model, prepares translated lines, creates speaker references and mixes the new voices back into the video.

Built for believable continuity
Preserve the speaker and the scene—not just the words.
Context, not literal fragments
Translation is adapted for spoken delivery and timing before speech is generated.
Picture preserved
When the source container permits it, Speakintosh copies the video stream and replaces only the audio mix.
A guided local pipeline
Import once, then let the stages stay understandable.
Drop an MP4, MOV, M4V, WebM, MKV, AVI, MPEG, TS or M2TS video.
Choose source and target languages plus the balance between original dialogue and the dub.
Run the local process, preview the result and export the dubbed video.
The footage stays on the workstation.
Transcription, speaker analysis, translation preparation, voice generation and assembly run locally. Additional models are downloaded once; the video is not uploaded for dubbing.
Straight answers.
Is it instant?+
No. Dubbing is a demanding, experimental workflow. Speed depends strongly on video length, speaker count and the Mac; a Pro, Max or Ultra chip with 32 GB or more is recommended.
Does it preserve the original sound?+
You can keep ambience and music while mixing in the dub, or retain more of the original dialogue for a voice-over style.
Does it perform lip sync?+
Not currently. Speakintosh aligns generated lines to dialogue windows, but it does not alter faces or promise frame-perfect lip movement.
