The latest update to Google’s text-to-speech capabilities allows developers to modify synthetic audio profiles using natural-language prompts. Now available via the Gemini API and Google AI Studio, the new ‘Voice Remixing’ feature for Gemini 3.8 Flash TTS enables users to adjust the timbre, pitch, and pace of a voice by providing text instructions.
Users can apply these adjustments to a custom persona or any selection from Google’s library of more than 2,000 preset voices. The company noted the tool can be used to create specific regional characteristics, such as a subtle Southern U.S. accent, or fictional sounds like those of a fire-breathing dragon.
