如何添加新规则？

[BridgetteSong]

针对分数的优化想要添加一个新规则，比如"点3/4/5击个人头像"改为”点三、四、五击个人头像“

class ShortBreak(Processor):

    def __init__(self):
        super().__init__(name='shortbreak')
        self.build_tagger()
        self.build_verbalizer()

    def build_tagger(self):
        rmspace = delete(' ').ques
        number = Cardinal().number

        tagger = (insert('one: "') + number + rmspace + delete('/') +
                  rmspace + insert('" two: "') + number + rmspace + delete('/') + insert('" three: "') + number + rmspace +
                  insert('"')).optimize()
        self.tagger = self.add_tokens(tagger)

    def build_verbalizer(self):
        one = delete('one: "') + self.SIGMA + delete('"')
        two = delete('two: "') + self.SIGMA + delete('"')
        three = delete('three: "') + self.SIGMA + delete('" ')
        verbalizer = one + insert('、') + two + insert('、') + three
        self.verbalizer = self.delete_tokens(verbalizer)

输出为：
`char { value: "点" } shortbreak { one: "三" two: "四" three: "五" } char { value: "击" } char { value: "个" } char { value: "人" } char { value: "头" } char { value: "像" }

File "extensions/_pynini.pyx", line 463, in _pynini.Fst.string
File "extensions/_pynini.pyx", line 508, in _pynini.Fst.string
_pywrapfst.FstOpError: Operation failed`

貌似可以正常解析，但是输出有问题，请问如何设置输出？build_verbalizer这里面的规则是什么？
