def capitalize_symbol(phrase):
    k = ""
    for i in phrase:
        if i != ' ':
            if i.istitle():
                next = chr(97 if i == 'z' else ord(i)+1)
                if next in ('a', 'e', 'i', 'o', 'u'):
                    next = next.capitalize()
                k += next.title()
            else:
                next = chr(97 if i == 'z' else ord(i) + 1)
                if next in ('a', 'e', 'i', 'o', 'u'):
                    next = next.capitalize()
                k += next.lower()
        else:
