2019/1/15  How long is the time lag of conversation?

It takes about 1 to 2 seconds for the voice of the partner (receiving side) to be reflected on the chat screen, and about 0.5 to 1 second until the text on this (calling side) is transmitted as voice.

As this side, you can use it like a conversation between voice phones you normally use and a chat tool, but when you become the receiving side, it becomes easier to be transmitted when you talk a little slowly.
