Set the scene with Gemini TTS
from Two Voice Devs Hosted by Mark and Allen
Roll tape and prompt! In this episode of Two Voice Devs, Allen and Mark explore how Google’s new advanced prompting guidelines turn developers into voice directors for Gemini Text-to-Speech. Instead of coding rigid SSML tags, you can now establish a scene, write stage directions, and give "director's notes" to shape a base voice's gender, accent, style, and pacing. Allen showcases a web app where he directs a single base voice—to play two entirely different characters: a rough Brooklyn cab driver and a classic Southern belle. The hosts discuss using natural language audio tags as cues for laughter, sighs, gasps, and more, and how these theatrical controls are coming alive in real-time with Gemini Live and Gemini 3.1 Flash TTS.
