Microsoft Teams Noise Suppression

Microsoft Teams Noise Suppression is an advanced AI-integrated audio processing layer that utilizes Deep Neural Networks (DNN) to distinguish human speech from non-speech background signals in real-time. Built on a proprietary dataset of over one million hours of clean and noisy speech, the technology employs a multi-layered signal processing pipeline to eliminate unwanted acoustic artifacts such as keyboard typing, sirens, pet noises, and fan hums. By 2026, the architecture has evolved to include 'Voice Isolation,' a personalized AI feature that learns the specific vocal profile of a user to filter out even other human voices in the background, making it the benchmark for open-office productivity. The system operates primarily through client-side edge computing to ensure sub-20ms latency, while leveraging Azure-based cloud processing for lower-tier hardware. Its market position is solidified as a standard utility within the Microsoft 365 ecosystem, removing the need for third-party audio filters in professional environments. The 2026 iteration integrates deeply with Microsoft Copilot to provide real-time audio quality diagnostics and automated gain control optimized for transcription accuracy.
