Is there any software that reads voice numbers while counting down?

Yes, there are some softwares that can realize this function, such as countdown APP "Countdown" (which can be downloaded from Apple and Android app stores). This application can set the countdown duration and start time. At the beginning of the countdown, the APP will read the remaining countdown time by voice, and can play music or vibration reminders at the end of the countdown according to the user's settings. In addition, there are other countdown apps and tools that can also achieve this function. You can choose the right software according to your own needs.
