You can choose the time signal voice from options like Japanese or English. Time signals can be scheduled in 30-minute intervals between 00:00 and 23:30 on the time setting screen. Once set, the time signal will play at the scheduled times even if the app is not running. (However, if Do Not Disturb mode is active, the time signal will not sound.) Please note that we do not respond to App Store reviews or questions posted there. For inquiries or requests, please contact us via the support email within the app. About the time signal, cuckoo clock, and chime sounds: The time signal does not differentiate between the hour and half-hour, nor does it indicate the specific time. The cuckoo clock chimes the number of hours on the hour and once at the half-hour. The chime distinguishes between the hour and half-hour but does not indicate the specific time. Use this option if you prefer not to have spoken announcements. The voice data for [Japanese Ami 12 o’clock] was provided by the following site: https://amitaro.net/ I'm sorry. I am not good at English. Thank you for interested.
