Inquiry on BMA580 for Voice Activity Detection in Smart Glasses

Hi,

For one of our smart glass products, we are planning to use Bosch’s BMA580 for user voice detection. Regarding the BMA580 for Voice Activity Detection in smart glasses, we have the following inquiries:

1. Could you please provide the operating range of audio frequencies that the BMA580 detects through speech-induced vibrations?

2. What is the optimal placement for the BMA580 on smart glasses to ensure effective voice activity detection?

 Thanks,

 Siddharth
