### Answer Retell AI is focused on voice-based interactions. The platform uses Automatic Speech Recognition (ASR) to convert spoken language into text, and Text-to-Speech (TTS) to convert AI responses back into natural-sounding speech. [(1) ]() [(2) ]() For audio interpretation, Retell AI voice agents already handle this natively—they listen to callers, transcribe speech in real time, and process the meaning using Large Language Models (LLMs) . [(1) ]() [(3) ]() [(2) ]() However, I don't have any information in the available sources about image interpretation capabilities within Retell AI. The platform appears to be specifically designed for voice/phone conversations rather than visual content processing. If you need image interpretation as part of your workflow, you might consider: - Processing images separately through an external vision-capable LLM (like GPT-4 Vision or Claude) - Passing the extracted information to your Retell AI agent via dynamic variables or tool calls For more details on what's possible, I'd recommend checking: - [Documentation]() - [Hire certified Retell partner]() Would you like me to try to provide a general answer about integrating external image processing with voice agents?

### Answer For chat interactions specifically, Retell AI does support a Chat Widget that you can embed on your website. [(1) ]() The platform also tracks Chat History for visibility into AI interactions. However, based on the available sources, I don't have information about image interpretation capabilities within Retell AI's chat functionality. The session type can be either

voice

or

chat

(accessible via the

{{session_type}}

dynamic variable) , [(2) ]() but the documentation doesn't describe any built-in image processing or multimodal input features for chat sessions. The underlying LLM models available in Retell AI (such as GPT-4.1, Claude 4.5 Sonnet, Gemini 2.5 Flash, etc.) [(3) ]() [(4) ]() [(5) ]() are text-based models configured for conversational responses—there's no mention of vision-enabled model variants being supported within the platform. If you need image interpretation in your chat workflow, you would likely need to: - Process images externally using a vision-capable API - Pass the extracted information into your Retell agent via dynamic variables or custom function calls For more specific guidance on chat capabilities, check: - [Documentation]() - [Hire certified Retell partner]() Would you like a general answer about integrating external image processing with chat agents?
