Keysha Payton, Haley Payton's mother, said she had been studying for the national spelling bee for about two months.
Vinay succeeded on gifblaar in the 20th championship round and then won the title on marocain. He missed after spelling "marram" incorrectly, a word that refers to a type of coarse, perennial grass.
As this year's champion, Vinay will earn $40,000, and Rajeev, the runner-up, will earn $30,000.
When Bee Week asked: What's it like to win the Scripps National Spelling Bee, Vinay responded: "It's like a dream come true, I'm so happy right now".
Mira Dedhia, an eighth-grader from IL finished third.
Ananya's victory broke the Bee's three-year streak of ending in a tie. "The biggest thing that she wants to do is sit and read", her father Vinay Sreekumar said.
Ananya was able to outlast 14-year-old Rohan Rajeev, who finished in second place.
The 12-year-old took home the prize by spelling the French word "marocain".
"OK, you really have to give me a word I know right now".
As the New York Times reports, Vinay sailed through the first 36 rounds of the spelling competition - correctly figuring out words we've never even heard of before, like konditorei and heiligenschein - before she even entered Thursday's championship round.
Earlier during bee week, the star of the event was 6-year-old Edith Fuller, who became the youngest contestant at the Scripps National Spelling Bee. But she has other plans for the future and hopes to invent a new kind of refrigerator, she said at a press conference.
"It was interesting to go back-and-forth for so many rounds", she said. She's a sixth grader at Clovis Unified's Fugman Elementary outside of Fresno. "Do you know the word 'covfefe?'". It was not long, however, before she was foiled by the word saccharomycete, a yeast fungus, and fell out of the competition.
