Pricing Model
FreemiumHume AI operates on a freemium model with structured monthly subscriptions and usage-based overage rates for developers and enterprises. The platform offers a Free plan providing 10,000 characters (~10 minutes) per month of Octave text-to-speech (TTS), 5 minutes per month of Empathic Voice Interface (EVI) speech-to-speech interactions, and 1 concurrent connection for non-commercial testing and evaluation.
Paid tiers begin with Starter at $3 per month (30,000 characters, 40 EVI minutes, and commercial rights) and Creator at $14 per month (140,000 characters, with introductory 50% discount at $7 for the first month, and unlimited voice cloning). For scaling production workloads, the Pro plan costs $70 per month (1,000,000 TTS characters, 1,200 EVI minutes, 10 concurrent streams, and $0.06/min overage), Scale costs $200 per month (3.3 million characters, 5,000 EVI minutes, 20 concurrent connections, and $0.05/min overage), and Business costs $500 per month (10 million characters, 12,500 EVI minutes, 30 concurrent connections, and $0.04/min overage).
For large-scale enterprise deployments, Hume AI provides custom Enterprise plans featuring unlimited capacity, custom overage pricing, dedicated infrastructure, SAML SSO, SOC 2 Type II compliance, custom SLAs, and hands-on engineering support. Pay-as-you-go overage rates for additional text-to-speech range from $0.12 down to $0.05 per 1,000 characters depending on subscription tier, and external LLM inference can be connected directly via BYO API keys.
