Siri can't hear me?!

Hi,

I was wondering if anyone could help me with an issue that just occur on my iPhone 6. I recently got a screen replacement on my phone and it works perfectly fine, but ever since, Siri can't here me. I have already tried seeng if the microphone or the iOS software was the problem, like dust or connection to the wifi, and etc. But none of the issues stated to check on my device was the results of Siri not being able to hear me nor able to respond to me. I need help on knowing if my iPhone is having any technical issues that I can't solve or need fixing.
