Before you decide
ElevenLabs Agents: Monthly plans include call minutes and concurrency. LLM usage is billed separately; external telephony providers bill their own carrier charges. Enterprise terms are custom. Hume EVI: Monthly plans include EVI minutes; additional EVI 3 usage is billed per minute on Pro, Scale, and Business, while TTS uses separate character allowances and rates. Ask both vendors to quote the same expected workload, required channels, and implementation scope. Include required subscriptions and usage charges before comparing the total; the listed starting prices alone may cover different work.
The recorded knowledge and data sources for ElevenLabs Agents include Knowledge-base documents from files, URLs and text; Retrieval-augmented generation (RAG). For Hume EVI, they include Not publicly documented. Ask each provider to demonstrate access for the exact systems you use, with permissions, freshness, and failure behavior. A source missing from this directory is not proof that a provider cannot support it.
Use the same representative calls, approved instructions, and escalation rules in both pilots. How does it handle interruption and uncertainty? Which actions can it complete, and which require approval? What context reaches a human during transfer? Record conversation quality, completed tasks, human handoffs, and total cost in the buyer worksheet. Check these specific cautions before launch: ElevenLabs Agents: Voice cloning requires authorization and governance. Budget for LLM usage, external carrier charges, overage and concurrency. Warm transfer messages require native Twilio; SIP REFER requires trunk support and has no warm message. Hume EVI: Empathic positioning is not proof of accurate emotion inference. Test false interpretations, cultural variation, consent, sensitive uses, and escalation.
