The Challenge

PolyAI powers AI voice agents for some of the world’s largest brands, handling customer service interactions at massive scale where every millisecond and every interaction matters.

At that level, voice becomes a core part of the experience. It needed to feel genuinely human and expressive rather than synthetic, while still supporting large volumes of simultaneous conversations. At the same time, latency had to stay consistently low to allow for real-time, back-and-forth dialogue.

Our Solution

Neuphonic worked with PolyAI to upgrade the voice layer of their agents.

We provided our TTS product for direct integration into their platform, enabling more natural and expressive speech while meeting the performance demands of real-time, high-throughput deployments.

The Results

The result is a noticeably more human customer experience across automated support.

Voice interactions feel smoother, more natural, and more engaging, while still operating at scale with low latency, helping turn customer service conversations into something closer to real dialogue rather than scripted automation.
