I am unable to create a replicated voice in Google AI Studio using gemini-3.8-flash-tts. After adding my own voice sample and recording the consent verification, clicking Replicate voice fails with: “Requested entity was not found.”
I purchased prepaid Gemini API credits and connected a paid API key. Re-recording and trying a newly created project/API key have not resolved the issue. I am accessing the service from South Korea.
Expected: successful voice replication. Actual: the error shown in the attached screenshot, with no voice created.
Could you investigate whether this is a Voices endpoint/provisioning issue, a project access issue, or a regional availability restriction? Please advise what diagnostic information is needed. I can provide project details privately, but will not post API keys or voice recordings publicly.
