Special English 又叫“慢速英语”，是VOA 专为全世界非英语国家初学英语的听众安排的一种简易、规范的英语广播节目。该节目创始于50年代末期，是VOA 的专家们研究如何与世界各地的英语学习者进行交际的产物。它正式开播于1959年10月。当时只面向欧洲和中东，但由于这个节目适合许多国家英语学习者的需要，所以它的广播对象不久就扩大到世界其他地区，并很快在全世界范围内产生了广泛的影响。现在这个节目对欧洲、非洲和拉丁美洲每晚广播一次，对加勒比地区每晚广播一次（星期天除外），对东南亚广播次数最多，每天上午两次，晚上三次。
30多年来，VOA 为了办好Special English节目，进行了大量的调查研究工作，对播音速度、内容及用词范围都作了具体规定，基本上达到了既能为英语学习者提供信息，又不损害英语本身风格的目的，使之成为VOA 独具特色，拥有最大量听众的节目。
美国著名词汇学家S. B. Flexmer 指明了Special English的三条标准，也就是它所“特别”的地方：
- You may have heard about a process called 3-D printing. It is where a machine creates a three-dimensional object -- one with height, width and depth. The machine uses plastic or a similar material to produce the object. Usually, the material is added one layer at a time, with the layering process repeated again and again until the product is ready.

- Before the Hubble Space Telescope, people saw the field of astronomy differently than they do today. American spacecraft did provide detailed pictures of Jupiter and Saturn, planets in our own solar system. But deep space, the place where nebulae and galaxies exist, remained mostly colorless -- until the Hubble Space Telescope.
- Plants have a biological clock that tells them when to produce leaves, seeds and other growth. A new study says understanding that clock may help scientists develop crops that can feed a growing population in an increasingly warmer world.
- Devices that help people walk were once thought to be difficult, if not impossible, to design. Until recently, such a device required electricity from an external power supply. Now, American scientists have built a small, wearable addition to normal shoes. Their new invention eases the load on muscles in the leg and makes walking easier.

- More than fifty years ago, researchers developed an oral vaccine against the deadly virus, polio. The vaccine, taken by mouth, is credited with almost stopping the spread of polio. Now, researchers are looking ahead to the time when the disease will exist only in a laboratory.
