Vesper And Synaptics Advance Far-field Voice Interfaces

Piezoelectric acoustic sensor wizard Vesper is collaborating with Synaptics to create durable, stable voice interfaces for Amazon Alexa Voice Service (AVS) devices. Synaptics is employing Vesper piezoelectric MEMS microphones for its two- and four-microphone Amazon AVS development kits.

 

Deemed the industry’s only piezoelectric MEMS microphones, Vesper mics are suitable for creating MEMS microphone arrays commonly used in far-field applications including the voice-activated smart speakers, smart home products, and Internet of Things (IoT) applications that include the Amazon Alexa Voice Service. Immune to common environmental contaminants, such as water, oil, particles and dust, Vesper microphones are the only microphones that do not undergo progressive failure due to contamination when deployed in the field. In a harsh environment such as a kitchen, the microphones stand up to greasy fingers, flour dust, splattering oil, and smoke.

Vesper microphones have a high signal to noise ratio (SNR) to promote clearly captured voice input, even at a great distance, as well as a high acoustic overload point (AOP) to support superior acoustic echo cancellation (AEC) performance.
