Blog post from Coval
Coval and Langfuse are being used together by Voice AI developers to address the complexities of testing, evaluating, and monitoring voice applications, as discussed by Coval's founder, Brooke Hopkins, and Langfuse's CEO, Marc Klingen. Voice AI applications require sophisticated testing strategies that include both high-level integration testing and detailed component evaluation due to their unique challenges such as audio quality, user interruptions, and real-time interactions. Langfuse offers tracing and observability features crucial for understanding application performance, while Coval provides comprehensive end-to-end testing and voice-specific metrics. Teams often start with Coval for quick integration and use Langfuse for detailed performance monitoring as their applications mature. The two platforms plan to integrate more deeply to enhance testing efficiency and reliability, and interested parties are invited to participate in the beta program for this upcoming integration.
