Voice mic & Sonos 5

Hi! I teach yoga and we play music via Spotify during some classes over two Sonos 5 speakers. The music sounds great, but it’s a big room with a lot of hard surfaces and even though I try to project, speak slowly and articulate my words, I believe students sometimes have trouble hearing me. I am wondering if there might be a way to mic my voice? I’ve read some of the threads and understand there are some issues with a delay. Any suggestions are appreciated. Thank you!
