Yellow.ai Launches Nexus Vox

Yellow.ai has launched Nexus Vox, a voice AI engine built as a single integrated system rather than stitched from multiple vendors' APIs.

Yellow's Nexus Vox supports more than 500 languages and dialects natively through an integration with Yellow.ai's proprietary multilingual AI models. It can be trained on 10 seconds of any human's voice, preserving the original speaker's timbre, cadence, and emotional range. It also offers sub-400-millisecond end-to-end latency from customer speech to AI voice response.

"Enterprise voice AI so far has been a Frankenstein's monster with several different vendor APIs stitched together, each adding latency, each introducing a point of failure, and none of them effectively helping resolve the problem. Every vendor has tried to fix it by adding another limb," said Raghu Ravinutala, co-founder and CEO of Yellow.ai, in a statement. "Vox is the first voice AI built from the ground up to ensure the voice and the brain share the same runtime. It's a completely different architecture."

Nexus Vox runs natively inside Yellow.ai's Nexus platform, sharing the same runtime as the conversational AI, knowledge base, and automation engine. It can be deployed across telephony (SIP/PSTN), web widgets, and REST APIs from a single configuration. And with real-time sentiment awareness, NexusVox adjusts tone, pacing, and escalation behavior mid-conversation.
