Lyon, June 2, 2026

The Lyon Civil Hospices (HCL) are taking a major step forward in the integration of artificial intelligence into healthcare by deploying EchoVault, a health data warehouse dedicated to medical voice data, developed by e-sensia.

For the first time, a hospital institution is equipping itself with a tool capable of structuring, querying, and leveraging patient voice data from medical dispatch and emergency call center interactions at scale.

This French first paves the way for a new approach to understanding, managing, and improving patient care.

Turning Thousands of Hours of Calls into Medical Intelligence

Every year, medical dispatch centers process millions of pieces of information. Until now, most of this data remained largely untapped.

With EchoVault, HCL now has a platform capable of:

Structuring a large-scale archive of voice data
Transcribing and analyzing conversations
Enabling advanced queries across all recorded calls

In practical terms, the platform can answer questions in seconds such as:

How many patients reporting chest pain associated with fever have called over the past few years?

Or, during a public health crisis, rapidly identify weak signals and monitor symptom trends within the population.

“Until now, this data existed but remained difficult to leverage. Today, it is becoming a genuine analytical tool for our medical teams,” said Clément Leroux, Head of PLATINES (Innovation, Environment and Health Platform) at Lyon Civil Hospices.

A Direct Lever to Improve Patient Care Pathways

Beyond operational management, the primary objective is clinical improvement.

By enabling detailed analysis of medical dispatch situations, EchoVault provides teams with:

A better understanding of decisions made
The ability to refine dispatch and triage protocols
An unprecedented feedback and continuous improvement tool

Most importantly, it offers the opportunity to improve tomorrow’s patient care through insights gained today.

“We finally have access to a comprehensive and actionable view of our activity. This opens up concrete opportunities to refine our practices and improve patient pathways,” emphasized the HCL Emergency Medical Services (SAMU) teams.

A Key Tool for Medical Research

EchoVault also provides a unique research platform for physicians and scientific teams.

Structured access to voice data enables researchers to explore correlations, analyze symptoms described in real-world conditions, and objectively assess medical dispatch practices.

This represents a paradigm shift: voice becomes a medical data source that can be exploited at scale.

The First Stage of a Broader AI Deployment at HCL

The EchoVault pilot is part of the HyCareALot experimental program, led by PLATINES, HCL’s digital health innovation hub, and funded through the France 2030 initiative.

It represents the first phase of a broader collaboration between e-sensia and HCL.

This initial stage focuses on structuring and leveraging historical data. It will be followed by the deployment of a real-time AI-assisted medical dispatch solution capable of analyzing calls live, as well as additional AI-powered tools supporting administrative workflows.

The objective is clear: empower healthcare professionals to act faster and more accurately while keeping physicians firmly at the center of decision-making.

Toward a New Generation of Medical Dispatch Tools

With EchoVault, HCL is reaching a significant milestone in its healthcare innovation strategy.

“EchoVault marks a turning point. For years, this data existed without being truly usable. Today, it becomes a practical lever to improve healthcare practices and prepare the integration of artificial intelligence into the daily work of caregivers,” explained Dr. Jean-Baptiste Perney, CEO of e-sensia.

About e-sensia

e-sensia develops artificial intelligence technology applied to voice analysis for emergency medical professionals. Its mission is to save lives by identifying life-threatening situations earlier through the analysis of vocal signals. Supported by several public institutions and healthcare organizations, e-sensia is currently expanding its deployment across France and internationally.
