What is the Vocabulary Builder?

The Vocabulary Builder is an AI-powered tool that automatically extracts specialized terminology from your documents and adds them to your workspace’s custom dictionary for improved speech-to-text accuracy. Simply upload PDFs or paste text before your meetings, and AI will detect phrases that are commonly misrecognized by speech-to-text — such as industry terms, product names, and technical jargon. These phrases can then be added to your dictionary in bulk, improving transcription accuracy for all future meetings.

How It Works

  1. Upload — Upload PDFs or paste text containing specialized terminology
  2. AI Analysis — AI automatically detects phrases likely to be misrecognized by speech-to-text
  3. Add to Dictionary — Add extracted phrases to your workspace’s custom dictionary
  4. Improved Accuracy — All future meetings benefit from better transcription of these terms
