# 🔊 Voice design and voice replication with Gemini 3.8 Flash TTS

## Executive summary

Google DeepMind introduced Gemini 3.8 Flash TTS and Gemini 3.8 Flash-Lite TTS, enabling advanced voice design and voice replication capabilities. Users can create custom voices using simple text prompts, specifying parameters like age, gender, accents, and language. Once a voice is designed in Google AI Studio, it can be integrated into applications using its unique Voice ID via the Gemini API, supporting over 100 languages.

## Key takeaways

- Voice Replication and Design: Users can replicate their own voice or design entirely new custom voices by providing a descriptive text prompt.
- Model Availability: The functionality is available through the new Gemini 3.8 Flash TTS and Gemini 3.8 Flash-Lite TTS models.
- API Integration: After designing a voice, the Voice ID can be used directly with the Gemini API to build multilingual applications.

## Technical details

- Voice Synthesis Models: The featured models are Gemini 3.8 Flash TTS and Gemini 3.8 Flash-Lite TTS.
- Voice Customization Parameters: Custom voices can be designed using a text prompt that specifies details such as age, gender, accents, and language. The system supports over 100 languages.
- Access and Workflow: The process is initiated at ai.studio/generate-speech, where users select 'voice design' or 'voice replication' to begin.

## Practical implications

- Build engineers can implement highly personalized and multilingual voice features into applications by leveraging the Voice ID generated through the Gemini API.
- This capability allows for the creation of sophisticated, character-specific AI assistants or narration systems that adapt to various linguistic and demographic profiles.
