Problem
Developing and maintaining AI voice agents requires extensive testing and debugging to ensure optimal performance and reliability. Current methods for analyzing call data and identifying issues are often manual, time-consuming, and lack comprehensive monitoring capabilities. This makes it difficult for developers to quickly iterate and improve their voice agents.
Solution
Fixa provides an open-source observability platform designed to streamline the testing and debugging of AI voice agents. The platform offers comprehensive tools to monitor key performance indicators (KPIs) such as latency, interruptions, and correctness of calls. By providing developers with detailed insights into agent behavior, Fixa enables faster identification and resolution of issues, leading to improved voice agent performance and a more reliable user experience. The platform's features include custom evaluations, alerting, and integration with communication channels like Slack.
Target Audience
Fixa is designed for AI voice agent developers and teams who need comprehensive tools to monitor, debug, and improve the performance and reliability of their voice agents.
Features
- Latency measurement: Tracks metrics like Time To First Word (TTFW) and p50/p90/p95 latency to optimize agent response times.
- Interruption flagging: Identifies instances where the voice agent interrupts the user, ensuring a natural conversation flow.
- Correctness checking: Allows developers to set up custom evaluations to verify that the voice agent is providing accurate and appropriate responses.
- Custom alerts: Notifies developers via Slack when the voice agent exhibits unexpected behavior or errors.
- Open-source testing package: Provides a readily available and customizable solution for voice agent testing.
