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.
FreemiumConvai's Creator module offers a Free tier ($0/month) for prototyping with a limited daily interaction quota, followed by paid tiers: Indie Dev at roughly $29/month, Professional at roughly $99/month, Scale at roughly $499/month, and Business at roughly $1,199/month, each increasing interaction quotas, character concurrency, and knowledge bank size. Beyond the Creator module, Convai offers an Enterprise module with fully custom pricing for large-scale or specialized deployments, along with Partner plans that operate on a revenue-sharing model with minimal upfront cost. Convai states its per-interaction pricing is designed to undercut the combined market rate of separately licensing speech-to-text, LLM, and text-to-speech services.

Hume AI Pros & Cons
Pros
- State-of-the-art emotional intelligence and vocal tone recognition
- Ultra-low latency bidirectional speech-to-speech interactions
- Extensive SDK support across web, backend, and mobile stacks
- Flexible integration with third-party LLMs like Claude and Gemini
- Accessible entry point with a free tier and plans starting at just $3/month
Cons

Convai Pros & Cons
Pros
- Genuinely differentiated focus on embodied, spatially-aware 3D characters rather than flat chatbot interfaces
- Free developer tier makes it easy to prototype before committing to a paid plan
- Strong multimodal capabilities: real-time vision, 65+ languages, 500+ voices, and high-quality lip sync in one platform
- Deep, mature integrations with the game engines developers already use (Unity, Unreal Engine, PlayCanvas)
- Avatar- and platform-agnostic, letting the same character deploy across web, mobile, VR, AR, and physical installations
- Built by an experienced engineering team with enterprise-grade security and on-prem deployment options available
Cons
- Full featured plans jump quickly in price, from Free to $29/month to $99/month as usage and concurrency needs grow
- Building genuinely lifelike embodied characters still requires real integration work in Unity, Unreal Engine, or another supported engine
- Best results depend on pairing with a compatible avatar and animation system rather than working entirely out of the box
- Voice bot / IVR customization and non-visual conversational use cases are a smaller focus than its core 3D character strength
- Enterprise-level features like on-prem deployment and dedicated support require contacting sales rather than self-serve setup
