写一个类似猪拉丁语的翻译

Question

我正在用Java编写一个程序，我应该将英语句子翻译成类似于猪拉丁语的语言，只是有一些不同的规则。 到目前为止，我已经编写了代码，但它似乎只是一次翻译一个单词而不是整个句子。你能告诉我哪里出错了吗？继承我的代码：

import java.util.Scanner;
public class PartD {
    public static void main(String[] args) {
        Scanner keyboard = new Scanner(System.in);
        System.out.println("Please enter a phrase to convert: ");

        String phrase = keyboard.nextLine();

        String[] words = phrase.split(" ");

        for(int i = 0; i < words.length; i++ ) {
            char firstLetter = (words[i].charAt(0));
            if (firstLetter == 'a' || firstLetter == 'e' || firstLetter == 'i' || firstLetter == 'o' || firstLetter == 'u'){
                String vowel = words[i] +"-eh";
                System.out.print(vowel);
            }else{
                String start = words[i].substring(0,1);
                String end = words[i].substring(1,phrase.length());
                System.out.print(end + "-" + start + "eh" );
            }
        }
        System.out.println( );
    }
}
