### Answer
Based on the official pricing documentation, ElevenLabs/Cartesia voices are priced at
$0.07/minute for the Conversation Voice Engine. [(1) ](
)
However, the total cost per minute shown in the agent cost estimate includes multiple components:
-
Conversation Voice Engine (e.g., $0.07/min for ElevenLabs)
-
LLM costs (varies by model—e.g., GPT-4o is $0.05/min, Claude 3.7 sonnet is $0.06/min)
-
Telephony costs (if applicable)
So if you're seeing ~$0.11/min, that's likely the
combined total of the voice engine + LLM, not just the ElevenLabs cost alone.
For example:
- ElevenLabs voice: $0.07/min
- GPT-4o mini LLM: $0.006/min
-
Total: ~$0.076/min
Or with a more expensive LLM:
- ElevenLabs voice: $0.07/min
- GPT-4o: $0.05/min
-
Total: ~$0.12/min
Check which LLM your agent is configured to use—that will explain the difference. You can use the [pricing calculator](
