difference between yao1 and yi1


Hi @YuQinCai, @Constance_Fang @Fiona and the ChinesePod team, my question is this:
1 sometimes pronounced as yao1, so what’s the difference between yao1 and yi1


Excellent question! In mainland China, 一 is pronounced as yāo when people are reading out numbers, especially telephone numbers. This is because 一 yī can sound similar to 七 qī,so saying yāo reduces the likelihood of confusion. In Taiwan, people do not use the yāo pronunciation.
