fixa

fixa is a specialized, open-source observability platform built to address the unique challenges of developing and maintaining AI voice agents. In the complex world of conversational AI, issues like high latency, awkward interruptions, and incorrect responses can severely degrade the user experience. fixa provides developers with a comprehensive suite of tools to monitor these critical aspects, enabling them to debug problems faster and systematically improve their voice agents' performance.

As an open-source solution, fixa offers unparalleled transparency and flexibility. It empowers teams to understand precisely how their voice agents are behaving in real-world scenarios. By visualizing call data and providing actionable insights, fixa transforms the development process from reactive troubleshooting to proactive optimization, helping to build more reliable, responsive, and human-like voice AI.

How to use fixa

Getting started with fixa is a straightforward process designed for developers:

1. Sign Up: Create a free account on the fixa website using Google or your email address.
2. Integration: Integrate the lightweight fixa SDK or API into your existing voice agent's infrastructure. This typically involves adding a few lines of code to your call processing pipeline to log relevant data.
3. Monitor Dashboard: Once integrated, your voice agent's call data will automatically stream to the fixa dashboard. Here, you can monitor key performance indicators (KPIs) in real-time.
4. Analyze Performance: Use the interactive dashboard to analyze metrics like Time To First Word (TTFW), p50/p90/p95 latency, and interruption rates. Filter data by specific agents, time periods, or other custom tags to pinpoint issues.
5. Set Up Evaluations: Create custom evaluation templates to automatically check the correctness of your agent's responses. For example, you can verify if an appointment was booked correctly or if a specific question was answered accurately.
6. Configure Alerts: Set up custom alerts via Slack to be notified immediately of critical issues, such as a sudden spike in latency or a failed correctness evaluation, allowing your team to respond proactively.

Core Features of fixa

• Advanced Latency Measurement: Tracks crucial latency metrics, including Time To First Word (TTFW) and p50/p90/p95 percentiles, to ensure your agent responds quickly and naturally.
• Interruption Detection: Automatically identifies and flags instances where the voice agent interrupts the user, helping you fine-tune turn-taking logic for smoother conversations.
• Correctness Evaluation: Allows you to define and run custom, automated checks to verify that the voice agent is providing accurate information and completing its tasks as intended.
• Centralized Monitoring Dashboard: An intuitive, read-only demo and a full interactive dashboard provide a holistic view of all calls, with powerful filtering and visualization tools to spot trends and anomalies.
• Proactive Slack Alerts: Customizable alerts notify your team of performance degradation or critical errors in real-time, enabling rapid issue resolution.
• Open Source & Developer-First: Being open-source provides transparency, community support, and the flexibility to self-host or customize. The platform is built with developers in mind, featuring a robust API.

Use Cases for fixa

• AI-Powered Call Centers: Monitor and improve automated customer service agents to reduce user frustration, ensure accurate task completion (e.g., bookings, support), and enhance overall call quality.
• In-App Voice Assistants: Optimize the performance of voice assistants within mobile or web applications, ensuring they are responsive, accurate, and non-intrusive.
• Pre-Deployment QA: Use fixa as a quality assurance tool to benchmark new versions of a voice agent, catch regressions, and ensure high performance before release.
• Continuous Performance Optimization: Continuously track agent performance in a production environment to identify bottlenecks, A/B test improvements, and make data-driven decisions to enhance the user experience.
