How to Build a Custom Vocabulary List for AI Transcription

Reviewed and updated: 21 July 2026.

A custom vocabulary list is a controlled glossary of words the transcription workflow is likely to misunderstand. It should help reviewers and, where supported, improve processing without becoming an uncontrolled copy of sensitive data.

Choose high-value entries

  • Frequent participant and organisation names.
  • Product, medicine, equipment or project names.
  • Acronyms with approved expansions.
  • Industry terms with unusual pronunciation.
  • Place names and codes.

Record useful fields

Field Purpose
Preferred term Approved spelling
Likely error Common transcript variant
Meaning Prevents incorrect replacement
Owner Person who verifies changes
Review date Removes obsolete entries

Minimise sensitive content

Do not preload unnecessary client, patient or case names into a shared glossary. Use matter-specific lists with restricted access where required.

Test effectiveness

Use a short script containing target terms and compare results before and after glossary use. Measure correction time as well as raw recognition.

How NERALVO Halo fits

NERALVO Halo recordings processed through DOWAY can be checked against a team vocabulary list, even where direct custom-dictionary features vary.

A good vocabulary list remains small, verified and owned. It supports human review rather than promising perfect transcription.
