Knowles Introduces Analog MEMS Microphone with 70 dB SNR for Voice and ANC Applications

Knowles continues to expand its audio input technology product portfolio, as voice increasingly becomes the primary user interface for Internet of Things (IoT) devices and hearable applications. The company announced its new SPM0687LR5H-1 analog MEMS microphone with 70 dB Signal-to-Noise (SNR), for far-field connected audio solutions, such as voice recognition, and active noise cancelling (ANC) headphone applications.

XMOS' VocalFusion 4-Mic Dev Kit for Amazon Alexa Voice Service (AVS) for far-field applications integrates Infineon’s high SNR MEMS microphones to ensure highest performance and reliability, creating the first Amazon AVS development kit with a linear mic array for far-field applications. The 4-Mic Development Kit features crystal clear voice capturing even in noisy environments. This enables commands to be accurately captured from across the room for processing by the Alexa cloud-based speech recognition system.

XMOS announced its VocalFusion 4-Mic Dev Kit for Amazon Alexa Voice Service (AVS). A far-field linear mic array solution available, the XMOS kit is ideal for developers who want to integrate Alexa into smart panels, kitchen appliances, and other commercial and industrial electronics. Being a leading supplier of voice and audio solutions to the consumer electronics market, XMOS can combine its unique silicon architecture and software at the interface between voice processing, biometrics and artificial intelligence.
