### Answer Based on the available sources, I don't have specific documentation about playing pre-recorded audio files to reduce token costs in Retell AI. However, here's what the sources do cover regarding IVR-style functionality: Conversation Flow for IVR-like Behavior The Conversation Flow feature provides finer control over conversations and allows you to define exact words spoken during and after each function execution. [(1) ]() You can also change the LLM for each individual node, which could help manage costs. DTMF/Keypad Navigation You can configure agents to handle DTMF input IVR systems that require pressing digits on the phone keypad. [(2) ]() One community member attempted to create a node that behaves "like a pre-recorded IVR — not a conversational assistant" with strict scripted responses. [(3) ]() What's Not Documented The sources don't explicitly describe a feature to upload and play actual pre-recorded audio files as a cost-saving alternative to LLM-generated speech. For specific guidance on cost optimization strategies or whether pre-recorded message playback is supported, I recommend: - Visit [Contact Sales]() - Visit [) Would you like a general answer based on my knowledge about typical approaches for this type of cost optimization?

### Answer The available sources don't provide a specific breakdown of individual voice provider costs within Retell AI's platform. What the sources do cover: Retell AI's pricing is $0.07+ per minute for AI Voice Agents, which bundles in usage fees from their providers (including TTS, STT, LLM, and telephony) on a per-use basis. [(1) ]() [(2) ]() The sources mention that premium voice models are "already factored into per-minute pricing" and that Retell AI integrates with various voice providers, but they don't list the individual cost differences between specific TTS providers like ElevenLabs, OpenAI voices, or others. [(2) ]() For detailed pricing on specific voice providers within Retell AI, I recommend: - Using the [voice agent cost calculator]() which allows you to check pricing based on LLM, voice engine, and telephony used - Visit [Contact Sales]() Would you like a general answer based on my knowledge about typical voice provider pricing tiers?
