Echo

Very simple, crystal clear sound. Picks up everything in the room from your smartphone and then broadcasts it to your amazon echo/google home/bluetooth speakers. The app requires your smartphone or tablet/kindle to have bluetooth along with being able to pair with bluetooth speakers. Works with the amazon dot and other amazon echo devices as well as google home speakers. No ads; the app picks up every sound you speak into the first device and broadcasts it crystal clear to wherever your bluetooth stereo or amazon echo device is at. To use, set volumes on both devices to low. Amazon and google devices respond to your voice commands with alexa, etc. For example, on the amazon echo, say, "Alexa, lower the volume." Connect your phone or tablet/kindle to your bluetooth speaker. Open the app and it will automatically play everything heard on the speaker/amazon/google device like an intercom. Pretend to be alexa and fool your kids. To avoid feedback, please have the devices at some distance. Works great and you will hear everything you say in a crystal clear fashion. Noise suppressor function, echo cancellation function, and automatic gain control where applicable.
