Development of the OnlineLab VCS® App for Voice Clinical Systems®

OnlineLab VCS® is an innovative mobile application that enables validated voice sample collection without the need for external equipment, empowering both healthcare professionals and patients to conduct detailed voice analysis with unprecedented accessibility.

🎯 The Challenge

Biomechanical voice analysis has traditionally required specialized equipment and controlled environments, significantly limiting its accessibility and scalability. The key challenges included:

• Accessibility: Enabling high-quality voice sample collection without relying on external microphones or specialized recording equipment.

• Accuracy: Ensuring recordings meet the technical standards required for reliable clinical analysis.

• Usability: Designing an intuitive interface tailored to both healthcare professionals and patients, enabling seamless navigation and interaction.

• Device validation: Ensuring that the mobile devices used comply with the necessary technical standards to deliver accurate and consistent results.

🚀 The Solution

Gloin addressed these challenges by analyzing the Proof of Concept (PoC) previously developed by the Voice Clinical Systems team and evolving it into a new generation platform: OnlineLab VCS®. The result is a fully enhanced mobile application accompanied by a new management platform featuring advanced capabilities:

• Device validation system: Implementation of a mechanism that verifies device compatibility and recording quality prior to capturing samples, ensuring optimal results.

• External-microphone-free recording: Optimization of the application to capture high-quality voice samples using only the device’s built-in microphone.

• Segment selection and analysis: Users can select specific segments of recordings for detailed and repeatable analysis whenever required.

• Custom report generation: Enables the request and delivery of multiple types of reports tailored to the needs of clinicians and researchers.

• Web user dashboard: Development of a complementary web platform that provides comprehensive data management and full control over collected information.

• Remote connectivity: Integration of features that allow professionals to connect with patients remotely, obtaining validated recordings without requiring in-person visits.
