Journee × Hume: Giving Enterprise AI Agents a Voice

Hume replaced OpenAI, Deepgram, ElevenLabs, and Langfuse, more than halving Journee’s costs and dramatically simplifying debugging and prompt management. EVI solved Journee's challenges across five dimensions: Affordable Scaling: Industry-low pricing enabled Journee to deploy voice agents across every customer touchpoint. Clean APIs: Hume’s complete, well-documented APIs and Python SDK reduced integration time from weeks to days. Consistent Enterprise Performance: EVI delivers latency ranging from 140 ms to 1.3 s, outperforming any other solution Journee tested, even under heavy multi-session load. Technical Precision: Hume’s API sends a reliable “end-of-speech” signal, allowing Journee to instantly release inference resources. Expressive and Natural Voices: EVI sends the first second of speech almost instantly, then streams the rest reliably, enabling natural turn-taking and emotional realism.

Finding Voice AI That Works at Scale

As Journee scaled their AI agent deployments, their existing voice provider created critical bottlenecks, such as: higher costs that limited Journee’s deployment across customer touchpoints, complex integrations that slowed their time-to-market for new clients, scalability issues causing inconsistent performance across hundreds of simultaneous conversations, and flat voices that failed to create an emotional connection.

Journee needed a voice AI solution that delivered real expressiveness without the prohibitive costs.

Christian Mio Loclair, Founder & CEO of Journee, states:

“At Journee, we build AI that feels truly human, emotionally intelligent, naturally expressive, and widely accessible.

Hume.ai has become a cornerstone of our Conversational Agents. Their voice tech captures nuance like nothing else we have seen; the stops, the breaths, the smiles, the perfect imperfections of everyday dialogue.

As product enthusiasts, we were blown away by how they treat empathy and tonal depth as a technical KPI, turning digital conversations into warm and casual chats.

Their accessible pricing also supports our mission to bring Human AI across the entire enterprise landscape.

Together, we are not just scaling conversations. We scale empathy.”
