第一种方法：

手写：

<template>
        <div>
            <el-button
                v-for="item in list"
                :key="item.id"
                @click="clickBtn(item.value)">{
       { item.value }}</el-button>
            <div v-html="voiceContent"></div>
        </div>
    </template>
    <script>
    export default {
        data() {
            return {
                list: [{id: 1, value: '你们'}, {id: 2, value: '什么'}, {id: 3, value: '来'}],
                select: '',
                text: '出来没有？你们什么时候来的？',
                selectIndex: 1
            };
        },
        computed: {
            voiceContent() {
                const regText = this.list.map(item => item = item.value).join('|');
                let index = 0;
                return this.text.replace(new RegExp(regText, 'g'), (a, b, c) => {
                    if (this.select == a) index++;
                    return `<span class="${this.select == a && this.selectIndex == index ? 'red' : 'yellow'}">${a}</span>`;
                });
            }
        },
        methods: {
            clickBtn(value) {
                const num = this.text.match(new RegExp(value, 'g')).length;
                if (this.select == value && num > this.selectIndex) {
                    this.selectIndex++;
                } else {
                    this.select = value;
                    this.selectIndex = 1;
                }
            }
        }
    };
    </script>
    <style>
        .yellow{
            color: yellow;
        }
        .red{
            color: red;
        }
    </style>
