One convenient way to address a large gathering without damaging your vocal cords is by using a loudspeaker.

The technology is pretty simple, and it’s already there in the Bluetooth speakers. When the Bluetooth speakers are connected to your smartphone, you can play songs, podcasts on the loudspeaker.

And you can use it as a portable loudspeaker. You need to install an app on your mobile phone. If you have an Android, you can install this app called Bluetooth loudspeaker from the Play Store.
Once installed, make sure w speaker is connected to your smartphone, and you will be able to use your smartphone as a mic, and whatever you are talking to add can be heard on the Bluetooth speaker.
