Online dictionaries are a wonderful resource. I recommend the Oxford Learner's Dictionaries website. https://www.oxfordlearnersdictionaries.com/definition/english As Ivan mentioned, the word "can't" has two pronunciations. https://www.oxfordlearnersdictionaries.com/definition/english/can-t?q=can%27t can’t short form of cannot BrE /kɑːnt/ ; NAmE /kænt/ The Oxford dictionary gives strong and weak pronunciation forms when they exist. https://www.oxfordlearnersdictionaries.com/definition/english/can1?q=can can1 modal verb BrE /kən/ ; NAmE /kən/ ; BrE strong form /kæn/ ; NAmE strong form /kæn/

A word of caution for non-native speakers - unless you have mastered the difference between /kɑːnt/ and /kʌnt/ , thread very carefully :)

It’s pronounced “cahnt” in Australian, British, New Zealand, Irish and South African English and “cænt” in American and Canadian English. So, both pronunciations are correct and it’s just one’s personal preference whether to pronounce it “cahnt” or “cænt”.
