The gold-standard open-source framework for professional-grade custom speech recognition and acoustic modeling.

Enterprise-grade Audio Intelligence API for real-time transcription and deep sentiment analysis.

Gladia is a high-performance audio intelligence platform engineered for developers and enterprises requiring ultra-low latency transcription and multi-dimensional audio analysis. Built on a proprietary orchestration layer that optimizes OpenAI’s Whisper models alongside specialized internal neural networks, Gladia achieves sub-300ms latency for live streaming and exceptional Word Error Rate (WER) scores even in noisy environments. By 2026, Gladia has solidified its position as the go-to infrastructure for the 'Voice-First' economy, providing seamless handling of code-switching (multi-language detection within a single stream), speaker diarization, and LLM-driven post-processing such as automated summarization and sentiment scoring. Its architecture is specifically designed for high-concurrency environments like call centers, virtual meeting platforms, and media localization houses. The platform bridges the gap between raw audio data and actionable business intelligence through a robust API that supports both asynchronous file processing and bi-directional WebSocket streaming, making it a critical component for AI agents that require real-time auditory perception.
