Problem with voice in Apple watch

Hello everyone, I have a problem with the VoiceOver voice on my Apple Watch. I use the Persian voice "Dariush", but sometimes the watch switches to the English voice. For example, when the English keyboard opens, it uses the English voice. It also happens in Control Center, in the first section ("Connected to iPhone"). This issue is very frustrating because every time it happens, I have to spend a lot of time changing the voice settings again. Is there any way to make VoiceOver use only one voice all the time?
