Washington ? Do you call a soft drink a “soda,” or “pop?” Do you say “you,” “you guys” or “you all?” Does the word “poem” have one syllable or two?

A bunch of students at Harvard University in Cambridge, Mass., are using the Internet to track the many ways Americans disagree about how to use or pronounce words.

The project is called the Dialect Survey, and anyone with a computer can participate for free. So far, more than 9,000 people have contributed their own words, phrases and pronunciations.

Since it’s a voluntary survey, the results aren’t scientific, but they provide a valuable insight into regional language differences, which stubbornly resist homogenization even in the age of near-universal television and radio.

For example, 72 percent of those who responded pronounce the state of Florida as if it were spelled “floor-i-da.” But 12 percent say “flah-ri-da,” 8 percent “flaw-ri-da” and 5 percent “flow-ri-da.”

The rest switch back and forth.

To name a nonalcoholic beverage, 54 percent of those who answered the Dialect Survey say “soda,” 24 percent say “pop,” 12 percent say “Coke” and 6 percent say “soft drink.”

For 76 percent of the respondents, the word for a sandwich with cold cuts, cheese and lettuce is a “sub.” Other choices are “hoagie” (7 percent), “hero” (6 percent), “grinder” (3 percent) and “poor boy” (2 percent).

Here are some other samples from the Dialect Survey. Percentages may not add up to 100 because minor variations have been omitted:

• Aunt: 75 percent of the respondents make it sound like “ant”; 11 percent, mostly in New England, pronounce it “ahnt.”
• Been: 65 percent say “bin”; 29 percent, mostly in the Upper Midwest, say “ben”; and 4 percent say “bean.”
• Coupon: 68 percent say “coo-pon”; 30 percent say “kyoo-pon.”
• Creek: 89 percent rhyme it with “seek”; 4 percent, mostly in the South, rhyme it with “sick.”
• Lawyer: 74 percent say “loy-er”; 21 percent say “law-yer.”
• Pajamas: 53 percent rhyme the middle syllable with “mama”; 45 percent, mostly in the Upper Midwest, rhyme it with “jam.”
• Poem: 68 percent speak this word with two syllables, “po-em”; 33 percent say “pome,” with only one syllable.
• Route: For 31 percent, this word rhymes with “hoot”; for 18 percent it rhymes with “out”; the rest said they used both pronunciations interchangeably.
