After erase, i++ is performed. That means one element is bypassed by the check.

Change the for loop to

for (int i = 0; i < word.length(); )
{
    if (word[i] == 'a' || word[i] == 'e' || word[i] == 'i' || word[i] == 'o' || word[i] == 'u')
    {
        word.erase(word.begin() + i);  // Removing specific character
    } 
    else 
    {
        i++; // increment when no erasion is performed
    }
}
