Dubbing adaptation and review
Dialogue that fits the scene.
Lexibraid helps localisation teams adapt translated dialogue to the scene. AI aligns scripts with video, flags timing and terminology issues, and suggests rewrites for human review before recording.
- Scripts aligned with the video, line by line
- Timing and terminology issues flagged before recording
- Adapters choose every final word
Flagged lines Sample data
LXB-101Line 112 — Mira: “We have to go back before the lanterns go out.”
Likely overrun
LXB-102Character name — “Pip” vs “Pipo”
Terminology inconsistency
LXB-103Line 47 — Captain Rook: “Oh, brilliant. Just brilliant.”
Possible meaning shift
Timing figures are estimates. Adapters decide every final line.

Why Lexibraid exists
Why Lexibraid exists
A great dub feels like the characters were always speaking your language. That takes skilled adapters, directors and actors. We want to give them back the hours lost to lines that never fitted the scene in the first place.
Our purpose
Help localisation teams catch timing, terminology and meaning issues early, so studio time goes into performance.
Why it matters
Problems found during recording ripple across translators, actors and editors. Finding them while the script is still a document is faster, cheaper and kinder to everyone involved.
The stakes
A growing amount of dialogue to adapt.

What changes
From finding problems in the booth to fixing them on the page.
Today
- Overlong lines discovered mid-recording
- Character terms tracked in personal notes
- Rewrites argued over without the scene in view
- Timing checked by reading aloud with a stopwatch
With Lexibraid
- Lines likely to overrun flagged before the session
- Terminology checked across scenes and episodes
- Rewrites reviewed beside the source line and scene
- Duration estimated per line, with the estimate labelled
The problem
A correct translation can still be impossible to perform.
A line can be accurate and still too long for the speaking window, inconsistent with a character’s established terms, flatter than the original emotion, or at odds with what is on screen. These problems are usually found in rehearsal or in the booth, when every fix costs studio time across translators, actors and editors.
- 01A five-second line written for a three-second shot
- 02A character’s nickname translated two different ways
- 03A joke that lands in the source but not in the dub
- 04A line that refers to an object no longer on screen
The solution
Find the problem lines before the recording session.
Lexibraid aligns source dialogue with the video, estimates whether each adapted line fits its speaking window, checks terminology across scenes and episodes, and suggests alternatives that the adapter can accept, edit or ignore.
Duration estimates
Estimates how long an adapted line takes to say, using a model for the target language, and flags lines likely to overrun.

How it works
From translated script to recording-ready script.
- 01
Upload
Add the video, source script, translated script and approved terminology list.
- 02
Align
Lexibraid aligns each line with the video and estimates its speaking time.
- 03
Review
Timing, terminology and possible meaning issues are flagged beside the source line and scene.
- 04
Export
The adapter approves the final wording and exports a timed dubbing script.
Timing estimates are estimates until checked against an actual performance. Recorded takes can later be checked against the approved timing.
Who it’s for
For the teams that make dubbed content work.
Dubbing and localisation studios
Catch timing and terminology problems before actors are in the booth.
Fewer retakesFilm and television distributors
Review adapted scripts consistently across vendors and languages.
Consistent quality checksAnimation production companies
Keep character names, catchphrases and voice consistent across a series.
Consistent charactersCorporate and training localisation agencies
Adapt training and corporate video to fixed timings at volume.
Faster turnaroundNamed organisation types are prospective customers. No affiliation or endorsement is implied.
What it will not claim
Estimates, not guarantees. Suggestions, not final lines.
Lexibraid is designed to support adapters, not to replace performance, direction or judgement. We are explicit about what the first version would and would not do.
- Timing estimates need checking against real performances
- Precise lip synchronisation is a later capability, not part of the first version
- The first version supports one language pair and scripted video
- Multimodal flags are prompts for human review, not conclusions
AI, used carefully
The model finds the tight lines. Adapters write the dialogue.
Dialogue is creative work. Lexibraid is built to save time on the mechanical checks and leave every creative decision with people.
What the AI does
- Aligns source dialogue with the video
- Estimates whether adapted lines fit their speaking windows
- Detects inconsistent names, phrases and character references
- Suggests alternative wording and explains what it changes
What it never does
- Approves or locks a line without an adapter
- Generates synthetic voices or replaces actors
- Claims precise lip sync in the first version
- Hides meaning lost in a shorter rewrite
People decide
Every line is confirmed, dismissed or escalated by dialogue adapters and dubbing directors, never by the model.
Evidence first
Each flag links to the video, source scripts, translated scripts and approved terminology behind it, so a reviewer can check the reasoning before acting.
Confidence shown
Scores come with a confidence level and the data gaps that lower it, so weak signals are not mistaken for facts.
Role-based access
Permissions are set per role: who can view, comment, assign, decide, escalate or export.
Complete audit trail
Assignments, notes and decisions are time-stamped with the person and reason, and can be exported.
Your data stays yours
Customer data is isolated per tenant, encrypted at rest and in transit, and never used to train models for other customers.
What we believe

- 01
Adapters are authors
Suggestions are options; the adapter writes the line.

Say what was lost
Every shorter rewrite explains any meaning it drops.
- 03
Estimates are labelled
Timing is an estimate until a performance confirms it.
- 04
Characters stay consistent
Approved terms and voice carry across a whole series.

No synthetic shortcuts
We support performers; we do not replace them.

A note from the founders
Why we are building Lexibraid.
Adaora has managed dubbing projects where a single overlong line held up a session while the team rewrote it in the booth. Multiplied across an episode, those moments became days.
Olamide directs and adapts dialogue and knows that the best fix usually comes from seeing the scene and the original line side by side. Sadiq has built speech models and knows how to be honest about the difference between an estimate and a measurement.
Lexibraid is our attempt to move that work earlier: show adapters which lines need attention and give them sensible options, while every word that reaches the actor is still chosen by a person.

The team
The people building Lexibraid
A proposed founding team for this concept.
Founder/CEO
Adaora Nwankwo
Localisation producer who has managed dubbing projects across film, series and animation.
Co-founder
Olamide Bankole
Dubbing director and dialogue adapter focused on performance and timing.
CTO
Sadiq Ibrahim
Speech and language ML engineer working on alignment and duration modelling.
Which languages are supported?
The first version would support one language pair with scripted video. More pairs would be added only after their duration models are validated.
Does Lexibraid do lip sync?
Not in the first version. It estimates whether a line fits the speaking window. Precise lip synchronisation needs specialised modelling and validation and is planned for later.
Does it create synthetic voices?
No. Lexibraid works on the script. Actors perform the lines.
Is Lexibraid a live product?
Not yet. Lexibraid is a proposed startup concept. The team is fictional, pricing is illustrative and the prototype runs on fictional data in your browser.
Does the AI make decisions?
No. Lexibraid flags, ranks and explains. Dialogue adapters and dubbing directors review the evidence and record every decision with a reason.
How would our data be protected?
In production, data would be encrypted, isolated per customer, access-controlled by role and never used to train models for other customers. Data-sharing terms are agreed before any pilot.
