计算机技术总是在朝着功能更强大、使用更方便的方向发展，用户的需求永远都是技术前进的动力。ASR和TTS的出现，让人和计算机的距离更加靠近，人机接口更加自然。由于技术（识别率不够高）和人们习惯上的原因，ASR离真正的普及还有一段距离。但是，在通信领域，由于CTI的广泛应用，计算机技术不断融入通信平台，这项技术正在如火似涂的发展、普及。VoiceXML就是一个很好的例子，它的应用就是以ASR和TTS作为基础的。-Computer technology is always moving in a more powerful, more convenient to use the direction of the development needs of the users will always be the driving force for technological progress. The emergence of ASR and TTS, the distance between people and computers closer, more natural man-machine interface. As a result of technology (recognition rate is not high enough) and people s habit of reasons, ASR from the popularity of the real there is quite a gap. However, in the communications field, as a result of the extensive application of CTI, computer technology into the communications platform, this technology is the development of fiery might coated, universal. VoiceXML is a good example, its application to ASR and TTS is based.
