Alexa, Microphone input audio specification. (Gain, Frequency etc.)

Hello, I'm developing a prototype commercial Alexa-enabled product.

I wasn't able to find microphone input audio specifications of Alexa-enabled products. There are few things mentioning what dB-scale, frequency response, frequency range, sensitivity, max SPL etc.

Any idea from anyone?

Thank you for your attention.
