# Provider Keys (Custom Mode Only)

VoiceHub allows you to use your own API keys when operating in Custom Mode. This offers maximum flexibility and data control, especially for enterprises and developers managing their own API usage.

### **Why Use Provider Keys?**

* Maintain full control over your usage, quotas, and billing with third-party AI providers
* Use credentials from your existing enterprise contracts or billing plans
* Securely isolate access and rotate keys as needed

Your keys are stored securely and used only for model routing during inference.

### **Supported Provider Types**

You can configure:

* STT Providers – Used to convert speech to text
* TTS Providers – Used to convert text back to natural speech
* LLM Providers – Used to generate conversation logic, answers, and summaries

### **Current Providers (and Growing)**

### **How to Add Keys**

1. Navigate to Provider Keys in the sidebar
2. Choose a tab: STT, TTS, or LLM Providers
3. Enter your API Key
   * Some providers like Azure also require a region
4. Click Save

Once keys are entered, they become available in Configuration > Models (under Custom Mode only).
