VM2000

Finally, the microphone for speech recognition

Ensures lifetime stability of microphone arrays, even in harsh environments.

 

 

Stable well-matched microphone arrays are critical for high-quality far-field voice interfaces. From smart speakers — which use up to eight MEMS microphones — to smart home automation systems, smart earbuds, smartphones and diverse IoT products, demand for microphone arrays is surging.

Despite their growing adoption, microphone arrays using capacitive MEMS microphones are prone to failure and degrade over time. When even a single array microphone drifts, either during system manufacture or after field deployment, the entire microphone array will fail and loose its directional beamforming capability. Such failures frustrate consumers — diminishing brand perception — and cause expensive returns for OEMs.

Fortunately, Vesper offers a solution. The VM2000 is a piezoelectric MEMS microphone that is natively immune to environmental contaminants such as dust, water, humidity, oil and particulate matter. This makes it extremely stable, so microphone arrays will always stay in sync, ensuring consistent beamforming performance of the array, regardless of the environment. In addition, only Vesper microphones are immune to stiction, which causes complete voice-interface failure. As a pure differential microphone, the VM2000 also offers outstanding RF protection and dynamic range. This is especially important when the array is close to a speaker.

Features

This combination of environmental robustness, reliability and stability — which is unique to Vesper microphones — makes the VM2000 the best overall choice in the market for smart speaker arrays.
