Choose ElevenLabs for an integrated starting point
Its Agents plans include a workflow builder and knowledge base. Our recommendation: use it to test whether your voice experience and business tools can be configured in one place. A successful demo still needs a separate check of call transfer and backend-action behavior.
ElevenLabs Agents plansChoose Twilio for application control
ConversationRelay connects your application over WebSocket and handles the speech interaction. Our recommendation: favor this path when an engineering team already owns your calling workflow and wants to keep business logic there. Include implementation and ongoing support in the decision.
Twilio application connectionWhat the price includes
USD unless stated otherwise. Usage examples exclude taxes and negotiated discounts. Confirm current terms before purchase.
ElevenLabs: allowances plus additional usage
Monthly Starter is $6 for 75 call minutes; Pro is $99 for 1,238 minutes. These are plan allowances, not unlimited calling. LLM usage is billed separately, and phone deployments also need telephony costs in the estimate.
ElevenLabs pricing and billing detailsTwilio: $70 per 1,000 Relay minutes is a subtotal
At the listed $0.07/min, 1,000 ConversationRelay minutes cost $70 before phone service, LLM usage, and your application costs. This illustration is not an all-in quote or a claim that it is cheaper than an ElevenLabs plan.
Twilio conversational AI pricingWhat to test before committing
Use one inbound support scenario with a knowledge-base question, an authenticated account change, and a transfer to a person. Record setup time, transfer context, and the full invoice components. Listen to the same script and interruptions on both implementations.
