Read full description

"Number Calling Machine" is an application that allows you to input a number and call it out in a natural voice. It's an easy-to-use app that requires just the push of a button. You can also display the number being called on an external large screen using AirPlay. The content of the text-to-speech synthesis can be customized freely in the settings screen. It can be used in various places such as restaurants, hospitals, and public facilities. The number calling machine using voice synthesis is an app that improves the visibility and auditory sense of customers and enhances the convenience and efficiency of service. When using AirPlay to display the number on an external monitor, the sound will come from the external monitor. Depending on the network environment, the sound may be interrupted or noise may be heard. Using the Apple Lightning - Digital AV Adapter MD826AM/A allows you to reliably stream audio announcements while displaying them on an external monitor.
