Perso AI vs Speechlab (2026): which should you pick?

Pick Perso AI if

• Fits if you localize finished videos and want to edit the script before export
• Makes sense if you want to try dubbing locally before paying

Look elsewhere if

• Not for you if you want more than one try for free
• Tight if your videos run past 3 minutes, which is the Starter cap
• Watch out: PRO's 900 minutes assume every credit goes to the Finch model
• Watch out: $3.49 is a first-month offer for new subscribers only
• Skip it if your computer is modest, since the desktop app needs a local model and enough power

Pick Speechlab if

• Fits if you want to dub a video into several languages and fix the script by hand
• Works for a creator wanting captions in SRT, TXT or JSON

Look elsewhere if

• Skip it if you dub a lot, as the free plan covers 2 projects and then it is paid by the minute
• Pricey if you add languages, as each one costs credits based on the source length
• Not for you if you need lip-sync, as it is listed for enterprise accounts only
• Watch out: linguist review, team roles and custom voices are Enterprise features with no published price

Perso AI

• Dubbing minutes depend on the model: the 900 minutes on PRO assume every credit goes to the Finch model, and Nightingale uses far more credits per minute.
• The Free plan includes one generation, and Starter caps each video at 3 minutes and about 7 minutes of dubbing a month.
• The $3.49 Starter price is a first-month offer for new subscribers only.
• The free desktop app needs a Perso account, a local model setup and enough computer power; premium voices, more languages and lip sync are online features.

Speechlab

• The free plan covers only 2 dubbing projects; further use is paid per minute of source media.
• Each added language costs credits based on the source duration, so cost scales with languages.
• Linguist review, team roles and custom voices are Enterprise features with no published price.
• Lip-sync is listed for enterprise accounts only.

AI dubbing and video translation

Upload a video or audio file or paste a link, pick a target language, and the platform translates and dubs it. The homepage describes dubbing in 99+ languages.

Voice cloning and lip sync

Dubbing can clone the original speaker's voice and adjust lip movement to the new language. Lip dubbing and script editing start on the Starter plan.

Script editor and speech to text

A subtitle and script editor, transcription and audio separation are part of the same workspace as dubbing.

Choice of voice models

Credits are spent at different rates depending on the model. The pricing page lists Finch at $0.11 a minute, Linnet 4 at $0.55 and Nightingale at $2.20 when a plan's credits all go to one model.

Free desktop app with local models

A Mac (Apple silicon, macOS 13 or later) and Windows 10/11 app offers unlimited dubbing with local voice and translation models. It needs a Perso account, and speed and quality depend on your computer.

Real-time dubbing for calls

Perso LiveDub dubs speech with the speaker's voice and lip movement in video meetings and works with Zoom and Google Meet.

Speechlab

Transcript and translation editor

Edit diarized transcripts and translations line by line, with SRT import, waveform editing and automatic speaker detection.

Voice matching

Replicate each original speaker's voice in the target language, or swap in a native voice; cloning availability varies by language pair.

Segment-level re-dubbing

Change one line of a translation and re-render only that segment, so credits are not spent on the whole file.

Captions and subtitles

Produce speaker-labeled captions and SRT or VTT subtitles from the same transcript, without generating a dub.

Flexible import and export

Takes MP4, MOV, MKV, WebM, common audio files and YouTube links; exports dubbed video or audio, subtitles and text.

Enterprise workflow

Bulk processing, API integration, human linguist review, lip-sync and invoice billing are offered to enterprise accounts.
