How PTC Learns Your Brand Voice and Translates Like You Do
PTC, WPML’s AI translation engine, adapts to the way you translate. As you edit translations – tightening a term, switching a link to its target-language version, shifting a sentence into a more casual tone – PTC watches for patterns in your edits and turns each recurring change into a rule you approve once. The next time the same situation comes up, the rule applies on its own. Over time, PTC translates in your brand’s voice rather than a generic version of the target language.
PTC never applies a pattern across your site without your approval. When it spots one, it emails you a digest and lists the new suggestions at WPML > Translations > Improve Translations. The four parts of brand voice PTC learns from your edits are:
- Brand terminology. The specific words you use for your products, industry, or audience.
- Brand tone. Whether your translations sound formal or casual.
- Country and dialect. Choices like Canadian French vs European French, when a language has more than one regional variant.
- Brand-asset consistency. Source-language links replaced with the matching target-language URL across the site.
Only PTC Learns From Your Edits
The legacy engines – DeepL, Google, and Microsoft – translate one segment at a time, with no awareness of the edits you make. They translate the same way every time, and keep being corrected the same way every time. PTC reads each page in full, learns from every correction, and applies what it learns going forward. The edit-learning loop is part of why PTC outperforms the legacy engines on the same source content. See PTC vs DeepL for the measured comparison.
Use the Local Version of External Links Across the Site
PTC notices when you keep replacing an external link with its target-language version, and offers to apply the same change everywhere else on the site.
For example, when you’ve changed several English Wikipedia links to their Spanish equivalents, PTC offers to swap every other instance across the site, so visitors always land on the article in their language. The existing pages get updated automatically.
Translate Your Branding and Terminology in Your Own Words
When you translate the same word the same way several times – or keep a name in its source language – PTC offers to add the rule to your glossary so every page on the site follows your choice.
For example, when you keep translating “stroke” as “ictus” in your Spanish content, or keep “GitHub” untranslated on an Arabic site, PTC adds the rule and applies it to every page where the term appears. The existing pages get updated automatically.
The same kind of pattern can show up in five different ways:
- A term you always translate the same way. “You’ve translated
strokeasictusseveral times. Add it to your glossary?” - A source-language word you keep untranslated. “You’ve kept
foilingin English several times. Add it to your glossary?” - A name you keep in its original alphabet, even when the target language uses a different one. “You’ve kept
Pearl Coast Resortin Latin script several times.” - A branded or technical term you keep in the source alphabet. “You’ve kept
GitHubin Latin script several times.” - A regional translation of a term. “You’ve translated
elevatorasascensorseveral times.”
Translate for the Country, Not Just the Language
If your edits keep favoring one country’s version of a language, PTC offers to switch to that version across the whole site.
For example, when your French translations keep using Canadian rather than European French – words like courriel, magasiner, and fin de semaine – PTC offers to switch to Canadian French. New translations then match the country you’re writing for, not just the language.
These changes apply to new translations. The suggestion walks you through how to refresh existing pages if you want them updated too.
Match the Tone You Use in Your Translations
Once your translations consistently sound more casual – or more formal – PTC offers to set that tone for every new translation across the site.
For example, when your French translations keep using “tu” instead of “vous” – or your German ones use “du” instead of “Sie” – PTC offers to set a casual tone going forward, so every new page reads in the tone you’ve chosen.
Like country and dialect changes, tone changes apply to new translations. The suggestion walks you through how to refresh existing pages if you want them in the new tone too.
Existing Pages Get Updated Too
When you approve a brand-terminology rule or a link-change rule, PTC also re-translates the existing pages where the rule applies, so the brand voice you’ve taught it lands across your whole site – not just on what you write next. You don’t have to send those pages for re-translation yourself, and the re-translation doesn’t draw down your word balance.
Re-translated pages take a short while to appear. PTC finishes the work on its side first, then WPML syncs the result onto your site – it can take a minute or two before the new version is visible.
