Segment

A segment is a unit of text used in translation workflows, typically consisting of a sentence, phrase, or short block of content. Translation tools divide source content into segments so translators can work on smaller, manageable pieces of text rather than entire documents at once.

Segments are the foundation of many translation technologies, including translation memory (TM) systems and CAT tools. Each segment is paired with its translated equivalent, allowing previously translated content to be stored and reused in future projects.

How Segments Are Used in Translation

Segments help organize and structure translation workflows.

Text Segmentation Content is automatically divided into segments based on punctuation, formatting, or system rules.

Segment-Level Translation Translators translate each segment individually while maintaining the overall meaning of the content.

Translation Memory Storage Once translated, the segment and its translation are saved as a pair in a translation memory database.

Segment Matching When similar content appears later, translation tools can suggest previously translated segments.

Why Segments Matter

Segments play a key role in enabling efficient translation and localization workflows.

• Improves translation efficiency by breaking content into smaller units
• Enables translation memory reuse across projects
• Supports consistent terminology and phrasing
• Helps translators focus on context within manageable text units
• Enables automation and translation workflow optimization

Segment-based translation allows organizations to scale multilingual content production while maintaining quality and consistency.

Segments in Modern Localization Workflows

Segments are widely used in CAT tools, translation management systems, and machine translation platforms. They allow translation technologies to analyze content more efficiently and provide suggestions based on previously translated text.

LILT’s AI-powered translation platform uses segment-based workflows to combine translation memory, adaptive machine translation, and human feedback.
