However, we can make some educated guesses based on the following:
* Her birthplace and upbringing: Susan B. Anthony was born in Adams, Massachusetts, in 1820. She lived in the northeastern US her entire life, so her accent would likely have been influenced by the speech patterns of that region.
* The time period: The late 19th century was a time of significant regional accents in the US. While it's unlikely that she spoke with a pronounced "Boston" accent, for example, she probably had a noticeable regional accent compared to someone from a different part of the country.
* Her social circles: As a prominent figure in the women's suffrage movement, Susan B. Anthony likely interacted with people from various parts of the country. Her accent may have been somewhat softened due to exposure to different dialects.
Ultimately, we can't say for sure what her accent sounded like. It's fascinating to think about, though, and it reminds us that even the most prominent figures in history had unique voices and experiences.
