Launch-ready translation and verified AI voiceover for a construction-sector market rollout in APAC and Latin America

The client and the project are anonymised throughout.

Sector: Construction and infrastructure

Language: English into Simplified Chinese, and Latin American Spanish voiceover

Service: AI Video Dubbing, GAI Translate, AI Verification, Human Translation & Localisation, Transcreation

The Challenge

A UK-headquartered publisher of contract standards and professional training for the global construction and infrastructure sector was opening two new markets at once. In APAC it was releasing a market edition of its flagship contract suite with supporting user guides, published alongside public authorities in the region, and needed web, email and social launch copy in Simplified Chinese written in a commercial register. In Latin America it had a five-part animated series on collaborative contracting and training, where an in-house Spanish recording attempt had produced audio too poor to publish. Both had to turn round in days, and the APAC copy had to reach an in-country reviewer inside a short availability window.

The Solution

Guildhawk ran both workstreams through one account team, pairing secure AI production with named human verification at each stage.

• Launch copy was produced with GAI Translate and post-edited by a vetted in-market Simplified Chinese linguist, briefed on the sales register the client wanted for the email and social assets and instructed to hold product and document titles consistent with the source.
• The raw AI draft and the post-edited version were retained as separate files, so the client can see what the human linguist changed, and an in-house quality check preceded delivery in bilingual side-by-side format for the client's in-country reviewer.
• For the animated series, Guildhawk supplied male and female Latin American Spanish voice samples for the client to choose from, matched to the AI voice already used on the English originals so the brand voice stayed consistent across markets.
• Final audio was recorded to the approved Spanish scripts and timed against the existing animations, with pauses set to the on-screen sequence and one WAV track delivered per episode for the client's video team to drop straight in.
• An independent in-market Spanish linguist checked every track against the approved scripts and returned a completed evaluation statement, with all files moving through Guildhawk's secure ISO 27001 environment and terminology assets retained for future editions.

The Results

• Around 1,700 words of web, email and social launch copy were delivered in Simplified Chinese on the quoted three working day date, in time for the client's in-country reviewer to sign off before a planned absence.
• All five Spanish audio tracks were delivered inside the quoted one working day turnaround once the voice sample was approved.
• The verified AI voiceover was quoted alongside conventional studio recording and came in at a small fraction of its cost, so the client could re-voice the full five-part series.
• Unusable phone-recorded audio was replaced with broadcast-usable tracks that carry a documented in-market human check, giving the client an audit trail for its use of AI voice.
• Terminology, translation memory and the retained draft and post-edited files supported a later client-requested amendment round, which Guildhawk returned as tracked changes against the delivered copy.

Why this matters for construction and infrastructure organisations entering new markets

A contract suite, its user guides, its training programme and the campaign that launches them all draw on the same vocabulary. Split that content across separate translation, studio and video suppliers and the terminology drifts, so the marketing promise stops matching the contract wording that professionals will be held to. Market entry also runs to fixed dates: a government partnership announcement, a conference, a training intake. Guildhawk handles the text, the audio and the video assets under one accountable contract, with 25 years of retained language assets, vetted in-market linguists in 200-plus languages and its own UK-built AI. Secure AI carries the volume and the speed, a named human verifies the output, and the record of who checked what stays with the client. That combination lets a sector body publish in a new language at campaign speed and still stand behind every word.
