The Windows 11 Insider Preview Build 26040 was made available via the Canary Channel last Friday—Microsoft's introductory blog explores a wide range of improvements and fixes—including a new Task Manager icon, support for USB 80 Gbps (AKA USB 4 Version 2), Colemak and Hebrew keyboard layouts and many more. The most significant change arrives with a wider deployment of Voice Clarity—this change has received plenty of press attention over the past weekend. The AI-powered feature was first released publicly back in 2022, but its rollout was product limited to compatible Surface devices. Microsoft's January 26 Insider Blog entry has an extensive escape plan—support is extending to "x64 and Arm64 CPUs" without any need for "extra hardware."

The relevant section stated: "We are expanding Voice Clarity which has been available on Surface devices and making it available to more people. Voice Clarity is a feature that enhances your audio experience on Windows with state-of-the-art AI technology. Powered by low complexity AI models, Voice Clarity cancels echo, suppresses background noise, and reduces reverberation in real-time. This feature is enabled by default and can be utilized by applications using Communications Signal Processing Mode, such as Phone Link and WhatsApp." Previously, this feature was only available on Surface devices that sported a Neural Processing Unit (NPU), so it is interesting to see Voice Clarity becoming less reliant on AI-tailored hardware.The insider blog suggests that a certain demographic could embrace this particular Windows 11 feature (to a greater degree): "PC games that use Communications Signal Processing Mode for their online communications will also benefit from Voice Clarity. Applications can provide a toggle for the Deep Noise Suppression stream effect to switch between AI models for voice only communications (Deep Noise Suppression enabled, the default setting) and generic audio content (Deep Noise Suppression disabled). With Voice Clarity, you can have confidence that your voice will be clearly heard during online meetings and enjoy smoother and more effective online communications."

It seems that Voice Clarity is being positioned as an alternative to a few rival applications (e.g. NVIDIA RTX Voice), although PC gamers are advised to not leap into Preview Build 26040 immediately. The blog's known issues section has been updated with an additional warning: "IMPORTANT NOTE FOR GAMERS!—Some popular games may not work correctly and cause a bugcheck (green screen) when launched on the most recent Insider Preview builds in the Canary Channel. Please be sure to submit feedback in Feedback Hub on any issues you see with playing games on these builds."
