The manual workflow

Why manual audio dubbing is frustrating

Traditional audio dubbing is costly, prone to timing desync, and requires days of manual sound engineering.

1

Desynced speech rhythm and cadence

Translated text lengths differ drastically from source speech, causing overlapping audio tracks or awkward unnatural pauses.

AI neural time-stretching matches frame-accurate cadence
2

Prohibitive multi-actor studio costs

Podcasts or meetings with multiple speakers require hiring separate voice actors, costing thousands of dollars.

Automatic multi-speaker diarization and voice assignment
3

Days of tedious manual DAW cutting

Audio engineers spend days aligning waveforms, cutting segments, cleaning background noise, and leveling audio tracks.
