Hello Google AI Team,

I am requesting to have my Google Cloud Project allowlisted for the Vertex AI Gemini Text-to-Speech / Audio Output capabilities (responseModalities: ["AUDIO"]).

I am currently migrating my workflows over to Vertex AI to build content-generation tools, but I am receiving the 400 Bad Request: You are not allowlisted to request audio output error.

Project Details:

  • Project ID: ai-voice-49381.

  • Project Number: 3548580891..

  • Region: us-central1

  • Models Requested: gemini-2.5-pro-preview-tts, gemini-2.5-flash-preview-tts , gemini-3.1-flash-tts-preview

  • Primary Use Case: Text-to-Speech audiobook and long-form storytelling voice processing.

Could you please review and add this project to the allowlist?

Thank you!
