October is the smart watch, Internet TV, the focus of the month, they are different from the smart phone, screen a large one small, buttons are not many, traditional touch screen, key control how to continue? So the "smart voice" demand was born, the current status of intelligent speech, voice recognition rate is high, but in the understanding of the point. Apple Siri led the smart voice burst Red 2007, domestic mobile phone Gionee has launched a "voice king" mobile phone, shouting "Zhang", it will automatically dial Zhang's phone, this, calculate intelligent voice? Don't get me wrong, this is just a kind of fool voice, is a single word recognition, a continuous statement on the "withered". Apple launched the era of Intelligent voice interaction in October 2011, when Apple released its iphone iphone, with an Siri voice control feature that helped users read text messages and weather, learn new tones and provide dialogue questions. Don't believe it? Take a look at a group of users and Siri's Test conversation. "Who Are you?" "I'm Siri." "Are you a girl?" "No" "Are you a boy?" "I don't think we have time to pull that off," I Like you, "and we're not going to make it." Siri exploded after the birth of the global, then Google, Baidu also launched a similar voice products. This year HTC, Motorola launched the flagship machine also has such functions, such as small I robot. Wear equipment frequency out of three technical links to the easy View analyst Wang believes that smart voice has been born with new requirements, "some wear devices have no keyboard, no touch screen, some even have no screen." "After Sony, Samsung released smart watches, October 17, Adidas also released the Micoach Smart RUN, coupled with the previous intelligence, Shanda and other domestic manufacturers to launch products, smart watch products have been exploding." In October, the music, millet, Ali Cool TV full pre-sale, three TV, music, cool open all support speech recognition function. The release of intelligent products has put forward new requirements for speech recognition. October 19, the reporter saw the music video TV, smart watch voice technology provider Cloud Acoustic team, its CTO Kangheng Dr. said, intelligent voice mainly contains three parts: speech recognition, semantic analysis, knowledge map. In order to demonstrate the effect, he uses the mobile phone voice control television: "Tomorrow Shanghai Weather", the television immediately responds "is inquiring for you", then the weather information then displays. The TV first understood Kangheng speech, then thought he was looking for the weather in Shanghai, and finally provided the weather information (knowledge map). Accuracy rate down to 80% even high-quality "products on the market, the accuracy of speech recognition will be higher, but to voice parsing will be lower, the knowledge map will be lower, the final accuracy can reach 80% is a quality product." Wang said, in these three links, semantic parsing technology is the most difficult. The current development situation is that the speech recognition accuracy is very high, according to Kangheng introduction, the cloud knowledge voice recognition accuracy rate is 95%. "To eliminate the remaining 5% is very difficult, need to start from every detail, the environmental noise first solution, 1%May be solved, then the accent problem solved a little, 1% went up, and then the sound sampling library to expand the point, 1% and eliminated. Kangheng said it could take five years to reach a 99% accuracy rate. Kangheng also said that semantic parsing and knowledge mapping is a very cutting-edge topic. "Like ' How many hairs do you have ', I can understand and understand, but I don't know the answer." Computers also need a long learning process. "Morning News reporter Wang
