Whisper Prompting
Keep prompts concise so Whisper spells names, brands, and jargon correctly.

A prompt is a short hint you set before recording. It helps Whisper spell uncommon words and handle jargon. Keep it short: Whisper reads only the last 224 tokens (≈ 900 characters); earlier text is ignored.
Why Use a Prompt
- Corrects spelling of names, brands, and technical terms.
- Improves accuracy for multilingual or specialized vocabulary.
Four Simple Rules
- Stay under 900 characters. Everything beyond that limit is ignored.
- List important names or terms first.
- Use exact spelling and capitalization you want in the transcript.
- Separate items with commas or periods. Short phrases work best.
