Actually, i don't believe that there is any other English word for that food. There are in North America restaurants which serve foods like this which are called Dim Sum restaurants. Many English speakers will refer to food of this type in general as dim sum. However, i have never known this type of food to be called anything other than dumplings.
There is a type of Chinese dumpling, usually the type which is fried in a pan after being steamed, and that particular type of dumpling is referred to as a "pot sticker":
Perhaps that name was given to this food by English-speakers, but i suspect that it was a name that Chinese speakers of English in North America gave to fried dumplings.
Additionally, the term dumpling is applied to a type of flour-based food which is common among Germans, and which is popular among Americans, as well. It is often referred to in the United States as a "drop dumpling." Since it is made from flour with vegetable shortening, and it is often cooked in soup or a soup broth, and is cooked by using a spoon to drop the dough into the broth, it is sometimes called a drop dumpling:
Unlike Chinese dumplings, usually made with rice flour, this is made with wheat flour, and is not filled with pork or vegetables as are Chinese dumplings. This is the "true," original European style of dumpling. Even though it is not stuffed as Chinese dumplings are, i suspect that Chinese dim sum foods were called dumplings because of the superficial resemblance to this food. German dumplings made with wheat flour are also called "bread dumplings," to distinguish them from dumplings which are made from potatoes (which, unsurprisingly, are called potato dumplings). Potatoe dumplings are usually baked or fried--they would fall apart if put into broth as "bread dumplings" are:
Finally, there is a dumpling popular in the South of the United States which is most often found in "chicken and dumplings." These are more like Chinese dumpling than German dumplings, because the dough is rolled out and not dropped into broth. But "rolled dumplings" are not stuffed with meat or vegetables, either. They are made from wheat flour (sometimes from corn flour--the meal made from maize--but that is uncommon), and are rolled out, and then cut into strips. They are then traditionally cooked in a chicken stew. Many cooks in the South will also cook them in a hot fruit compote to make a dessert. Here's a picture of chicken and dumplings, Southern style:
