ASR Initialization Failure in Multilingual Mode – MiniMax + Turkish

I am writing to report a critical issue we have been experiencing with ASR initialization failures when using Multilingual mode on one of our agents.

**Issue Summary:**

When the agent language is set to Multilingual, all ASR providers fail to initialize and the call drops within less than one second. However, when we select Turkish or English as a single-language setting, the agent works without any issues.

Agent language choice:

Your platform documentation includes multilanguage support in Turkish.

https://docs.retellai.com/agent/language#set-language-for-your-agent

**Environment:**

- TTS Provider: MiniMax

- Voice Model: Camille

- Language Setting: Multilingual

- Platform: Retell AI Dashboard

**Observed Behavior:**

- Single language (Turkish): ✓ Working

- Single language (English): ✓ Working

- Multilingual: ✗ ASR fails to initialize

Additionally, we have noticed that Turkish (TR) does not appear in the supported language list when hovering over the Multilingual option in the dashboard. According to your documentation, MiniMax does support Turkish — so we believe this may be a configuration or compatibility issue specific to Multilingual mode.

**Affected Call IDs:**

- call_4ddfa975efa57dca09e8d26c340

- call_287f56cb9bcb78b623c917fa8b2

- call_d33a94760e7e42d65283eb32623

**Error Log Sample:**

Call closed in error: ASR closed with reason: All ASR providers failed to initialize

Could you please investigate whether Turkish is supported in Multilingual mode for MiniMax, and look into the ASR initialization failure using the call IDs provided above?

We would appreciate a prompt response as this is directly impacting our production environment.
