Measuring what matters to make every call, app, and AI interaction dependable

You know that feeling when a call just works? No dropped words. No robotic glitches. No wondering if the other person heard you correctly. That's not luck. It's engineering. And at Zoom, it's backed by relentless testing and measurement.

 

We all know quality matters. When work spans time zones, deals close over video, and support teams can connect with customers instantly, quality forms the foundation of trust. It determines whether your work time is productive or frustrating.

 

That's why quality matters so much. It's the difference between a productive meeting and a frustrating one. Between closing a deal and losing momentum. Between feeling confident in your tools and constantly second-guessing them. The 2025 quality reports, independently conducted by TestDevLab and commissioned by Zoom, showed that when you obsess over the details, people feel the difference:

 

Obsessing over these details is what makes every interaction feel effortless. Here’s a closer look at how AI Companion, Zoom Phone, and Zoom SDK for Web are setting the standard for quality.

AI is everywhere now. But not all AI is helpful. Sometimes it returns generic results. Sometimes it hallucinates. And sometimes it just doesn't get what you're trying to do.

 

The 2025 AI Quality Report, commissioned by Zoom and evaluated by TestDevLab, shows how AI Companion is getting better at understanding context, summarizing accurately, and responding in ways that actually make sense. Testing revealed that Zoom leads in word error rate for transcription accuracy and demonstrates superior performance in closed captioning quality, with significantly reduced flickering (the rewriting of text on screen) compared to competitors. Through systematic testing of tasks like meeting summaries, email drafts, and conversation insights, they measured how well AI Companion performs in real-world scenarios.

 

Your voice is your most powerful tool at work. Whether you're closing a deal, supporting a customer, or just checking in with a teammate, you need to sound like yourself, not like you're calling from a tin can.

 

The 2025 Phone Audio Quality Report, commissioned by Zoom and conducted by TestDevLab (a leading independent testing lab specializing in audio and video quality assessment), shows how Zoom Phone has pushed audio clarity to new heights. Through rigorous testing across codecs, network conditions, and acoustic environments, Zoom measured exactly what makes a call feel natural. Even under extreme conditions with up to 70% packet loss, Zoom Phone maintained superior audio quality compared to competitors, with quality scores remaining strong where other platforms degraded significantly.

 

More organizations are relying on Zoom's technology inside other apps people use every day thanks to Zoom's SDKs.

 

The SDK for Web Audio & Video Report, commissioned by Zoom and tested by TestDevLab, breaks down how Zoom's embedded communication technology performs across browsers, devices, and real-world network conditions. With Version 2.x of the SDK, Zoom achieved first-place rankings in frames per second and video quality metrics, and demonstrated 40% better resource utilization compared to the previous version. (See chart below for comparisons with both the previous version and competitors.) Developers building telehealth, tutoring, or support experiences can embed Zoom-quality video and audio backed by strong results across bandwidth limits and real-world environments.

 

Here's the thing about quality: most people only notice it when it's missing. A dropped call. A blurry video. An AI summary that's completely off-base. This technology is supposed to help you, not get in your way.

 

The 2025 quality reports, independently conducted by TestDevLab and commissioned by Zoom, serve as a testament to Zoom's commitment to measuring and proving that the platform you rely on works as intended.

 

Because when communication works — when your AI assistant actually helps, when your voice comes through clearly, when your app integrates seamlessly — you're not thinking about the technology anymore. You're thinking about the conversation.

 

And that has a real impact. Research shows that when digital tools work smoothly, workers experience lower cognitive load, less stress, and higher satisfaction. High‑quality, natural communication reduces mental effort and helps people stay focused and happy at work.

 

That's the kind of quality worth measuring. And that's the kind of quality Zoom works to deliver. When it's done right, great technology disappears, leaving only connection.
