“Alert” Service or Trading Room Request

I have previously used Benzinga Pro "Squawk" as throughout the day they read out major market moving news and unusual volume moves. However, it's quite expensive and I'm hoping to find a decent inexpensive replacement, hopefully free. Can anyone please help and recommend a service they have used? I'm open to a trading room on any platform but not one that's constantly making noise and instead they just read out specific announcements.
