I’ve seen a few posts about the spelling of words for British English.
While I have not been able to consistently get the AI to give the results I needed, I put together a function to replace words in the resulting text. I used a regex with a word list. Essentially, I look for words in the list, and swap for their alternate spelling. The regex needs a \b at both ends (so it only gets whole words)
You also need to handle the upper and lower case to make it match the original text. Here is the word list
acknowledgement acknowledgment
aeroplane airplane

And here is a C# function that you could modify (it handles the upper and lowercase etc)
public static string SwapWords(string sourcetext, string fromword, string toword)
{
return Regex.Replace(sourcetext, $@"\b{fromword}\b", match =>
{
string word = match.Value;
if (char.IsUpper(word[0]))
{
if (word.ToUpper() == word)
{
return toword.ToUpper(); // All caps
}
return char.ToUpper(toword[0]) + toword.Substring(1); // First letter capitalized
}
return toword; // All lower case
}, RegexOptions.IgnoreCase);
}
I hope this can be helpful to others
