Hoarse Voice
Because croup can make the voice box and throat become swollen and inflamed, it would affect the sound of our voice. If you have a very deep and hoarse voice that is quite like a barking seal, it is a clear sign of croup. It can be hard for many people to differentiate this sign, especially in mild cases. However, the sound is relatively distinctive that most doctors and healthcare providers can easily tell you over the phone whether it is caused by croup or not. [3]
