What is Device-Test?
Device-Test is a free collection of browser-based tools for checking everyday devices before meetings, presentations, gaming sessions, or troubleshooting. Start with the device you want to check, open its test page, and use the visual feedback to see how it responds.
Audio and video tools include a microphone test with real-time audio visualization and volume levels, a camera test for previewing your webcam feed, and a screen-sharing test for checking presentation capabilities. The speaker test includes a tone generator, stereo channel checks, and a frequency sweep. Together, these tools help you check the basic inputs and outputs used in online calls.
For input devices and displays, Device-Test provides a keyboard test with visual feedback and progress tracking. The display test uses solid colors to help you inspect dead pixels, bright spots, and backlight bleeding. The Input Performance Lab offers focused modes for click speed, scrolling, and reaction time. A touch test checks multi-touch capabilities, pressure sensitivity, and drawing accuracy.
Device-Test also includes tools for controllers and connected hardware. The gamepad test displays buttons, sticks, and triggers in real time. The MIDI test combines a virtual piano with event logging so you can inspect controller input. A Bluetooth test provides a service and characteristic explorer for supported devices.
Additional tests cover network speed, latency, and connection quality; battery level and charging status; location services; vibration patterns; ambient light readings; and gyroscope and accelerometer input. Availability of individual capabilities depends on the device and browser being used.
The site brings these checks together in one place, making it useful for a quick check before a call or a more focused investigation of a keyboard, display, controller, or sensor. Each tool has its own page, so you can go directly to the test you need and return to the main collection when you want to check another device. Device-Test emphasizes local browser-based testing and straightforward feedback rather than a complicated setup.
What is NovaSynth by Noveum?
NovaSynth by Noveum is a self-service platform for automated voice AI testing. It is designed for developers and teams building voice agents who need repeatable ways to exercise conversations before and after changes. Instead of relying only on a person to place each test call, teams can configure synthetic callers, define scenarios and run batches of calls.
A test starts with the caller and the conversation goal. The persona editor supports settings such as tone, speaking speed, interruptions and background noise. These controls let a team represent different calling situations while keeping the intended scenario explicit. A developer can use this configuration to examine how a voice agent behaves when callers speak or interact differently.
NovaSynth supports test calls over phone or LiveKit. After a run, teams can inspect call recordings, transcripts and evaluations. Recordings provide the audible conversation, while transcripts make it easier to inspect the exchange in text. Evaluations help a team review the resulting conversations against its testing needs. The purpose is to make investigation and repeat testing part of the voice agent development workflow.
Batch calls help a team execute several configured tests without manually conducting every conversation. Reusing scenarios after a prompt or application change supports regression checks. Teams can compare observed behavior and investigate calls that need closer attention. NovaSynth is a testing tool for the agent being developed; it does not replace the need to define appropriate scenarios or review the results.
NovaSynth is part of the Noveum platform. Noveum provides a monthly free credit allowance shared across its features, with paid plans available. Voice testing consumes credits, and evaluations can add usage costs. The free allowance is not unlimited voice calling. The official product and pricing pages provide current plan details and the entry points for getting started. The platform is available through the Noveum web application.
What problem it solves
Manual voice agent test calls are difficult to repeat consistently across caller personas and scenarios after application changes. NovaSynth automates batches and supplies recordings, transcripts and evaluations for investigation and regression checks.
