Linguistic testing

Linguistic testing is the process of reviewing localized content to ensure it is accurate, natural and culturally appropriate for its target audience. It verifies that translated text fits correctly within user interfaces, maintains intended meaning and reflects the tone and terminology of the brand.

Description

Linguistic testing takes localization beyond literal translation. It’s the final step in ensuring that a product, website or piece of content feels truly native to each market.

This process involves expert linguists and In-country review reviewers evaluating translated text in its real context – inside software interfaces, websites, mobile apps or multimedia content. They check for Linguistic quality, layout issues, truncation, mistranslations and formatting errors, as well as cultural relevance and consistency with approved terminology. Linguistic testing is typically performed after Functional testing, when all technical validation is complete. It confirms that the user experience (UX) – from button labels and error messages to marketing headlines – feels fluent, intuitive and on-brand.

Example use cases

  • Software: Verify text display, tone and context across interfaces.
  • Web: Review headlines, menus and navigation in multiple languages.
  • Marketing: Ensure creative adaptation aligns with brand voice and emotional tone.
  • Ecommerce: Validate that localized product descriptions and checkout flows read naturally.
  • Regulation: Check accuracy of legal, medical or compliance terminology.
