The Challenge

Overcoming Language Barriers in Global Business

International business operations often face logistical bottlenecks and high costs when relying on human interpreters. The client required a scalable solution to provide instant translation for their agents directly within their existing PBX infrastructure, without the latency and scheduling limitations of human translators.

High costs and limited availability of human interpreters

Limited number of languages agents can speak fluently

Technical complexity of integration with legacy PBX systems

Imperative for low latency to ensure natural conversation flow

Our Solution

AI Real-time Translation Platform

We implemented robust Golang software that transparently integrates with PBX exchanges. The software uses advanced AI models to translate the agent's speech to the caller's language in real-time, ensuring continuity and quality of communication.

PBX Integration

Integration with Asterisk and FreePBX systems via SIP protocol for reliable call routing.

AI Speech-to-Speech Engine

Advanced processor combining speech recognition (STT), neural translation, and speech synthesis (TTS) for natural translation.

Low-Latency Streaming

Golang-based audio streaming architecture with sub-second latency for uninterrupted conversation.

Voice Cloning & Synthesis

High-quality speech synthesis that retains the professional tone of the agent in the target language.

Quality Assurance & Analytics

System for real-time model performance monitoring, with automated recovery mechanisms.

The Outcome

Global Connectivity Without Borders

Implementation of the AI platform enabled access to multilingual support, reducing costs and enabling agents to operate globally.
