A walkthrough of Gemini's custom voice features

Gemini's voice customization feature has been rolling out over the past couple of days, available in both real-time conversations and regular chats. The core idea is to record a few clips of your own voice so the AI learns your timbre and tone, then uses that voice to respond to you in subsequent conversations. I spent two days testing it from start to finish; it works, but there are a few pitfalls you need to avoid beforehand.
