Hello Community, I have a critical issue with the Cloud Text-to-Speech API in my project (PII Removed by Staff). My API calls are failing for all Persian (fa-IR) voices with a 400 “voice does not exist” error. However, API calls for English (en-US) and French (fr-FR) WaveNet voices are working perfectly using the same setup. - Successful Calls (Working): en-US-Wavenet-A, fr-FR-Wavenet-A - Failed Calls (Not Working): fa-IR-Wavenet-D, fa-IR-Standard-A This proves my code, authentication, and billing account are all correctly configured. The issue is specifically with the provisioning of Persian language voices for my account. Has anyone encountered a similar issue where specific languages are unavailable despite a correct setup? Thank you.
