Tech Stack
PyTorch, TensorRT, Python, Node.js, WebRTC
Primary Impact
Delivered highly responsive, natural conversational flows.
The Challenge
An enterprise contact center provider was modernizing their virtual agents but faced challenges with existing text-to-speech (TTS) solutions. The APIs they tested exhibited noticeable latency and robotic prosody, creating friction in customer interactions and limiting the effectiveness of automated support flows.
The Solution
We developed an optimized inference pipeline focused on minimizing end-to-end latency for voice synthesis. By leveraging NVIDIA TensorRT for acoustic model optimization and deploying the service closer to edge networks, we significantly reduced the generation and streaming overhead. We integrated WebRTC to ensure real-time audio delivery with minimal buffering.
The Impact
The resulting engine allowed the client's virtual agents to hold much more natural and fluid conversations. The reduction in response latency and improvements in vocal prosody led to increased user engagement, higher self-service resolution rates, and consistently better customer satisfaction feedback.
