Dictionary

Custom dictionaries work at the speech recognition level, helping transcription models correctly recognize and spell domain-specific terms, names, brands, and technical jargon. This feature is supported by GPT-4o Transcribe, GPT-4o mini Transcribe, Soniox Realtime, and Soniox Async models.

How to Access

Navigate to Dictation Models in the settings, then click the Settings button next to a supported model.

Setting Up Your Dictionary

The model settings dialog contains a Prompt (Dictionary) field. Enter context or specific terms you want the model to recognize accurately.

Tips for Effective Dictionaries

• Include proper nouns: Names of people, companies, products, and places that might be uncommon.
• Add technical terms: Industry-specific jargon, acronyms, or specialized vocabulary.
• Provide context: A brief sentence describing what you'll be discussing helps the model understand the domain.
• Use correct spelling: The model will follow the exact spelling and capitalization you provide.
