Dictionary
Improve transcription accuracy by providing context and custom vocabulary to supported models.
Custom dictionaries help transcription models correctly recognize and spell domain-specific terms, names, brands, and technical jargon. This feature is currently supported by Soniox and GPT-4o-transcribe 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
In the model settings dialog, you'll find the 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.
