Ask HN: How to boost Gemini transcription accuracy for company names?

Summary

I’m using Gemini for speech-to-text and it often misrecognizes company names and acronyms.Is there any way to use a custom lexicon or vocabulary with Gemini to improve recognition accuracy? If not directly supported, what are practical workarounds people use — e.g. preprocessing prompts, fine-tuning, or combining Gemini with another ASR that supports phrase boosting?
