How to pronounce“calf”in English

“And Goldenhorns calved. A great day in the wilderness, a joy and a delight. They gave her flour-wash, and Isak himself saw to it there was no stint of flour, though he had carried it all the way himself, on his back. And there lay a pretty calf, a beauty, red-flanked like her mother, and comically bewildered at the miracle of coming into the world. In a couple of years she would be having calves of her own.”

“We find now, that instead of leather made from sheep, calf, goat, and pig-skins, each having, when finished, its own characteristic surface, that sheepskins are got up to look like calf, morocco, or pigskin; that calf is grained to resemble morocco or so polished and fattened as to have but little character left; while goatskins are grained in any number of ways, and pigskin is often grained like levant morocco. So clever are some of these imitations that it takes a skilled expert to identify a leather when it is on a book. . . I am inclined to consider that calf, as a sound leather, has been manufactured out of existence, for it is unusual to find a 19th century calf binding of more than fifteen years old that does not show signs of decay.”
