Thank you.Well Fig.5 iTranslate Voice With the help ofan electronic translator,like iTranslate Voice (as shown in Fig.5),it became possible to communicate with a foreigner even if you don't understand the language of each other.What you need to do is just to speak to the computer,and then the electronic translator,a combination of speech recognition technology,machine translation technology as well as speech synthesis technology,can help to convert what you said into words,translate them and speak out in another language.What's more,we can also practice oral English by talking to a computer,Reading Assistant2 being a vivid example.Applying the system of speech recognition in recreations is undoubtedly very interesting.Nuance Communications,the largest enterprise on this technology, even introduced one kind of software,named Dragon Gaming Speech Pack.The feature of this production is that players can give instructions like“squat'”“aim”“reload”to complete the game,. which is no longer dependent on mouse and keyboard control. All in all,the application has a promising future.It is enough to make big difference of your life though it's still in its start stage.We are looking forward to more exciting innovation of speech recognition technologies. 5.2 Lip-re ading 5.2.1 The brief introduction of lip-reading Lip-reading refers to a progress of understanding other's words by recognizing the shape of changing mouth.And computer lip-reading system combines video signals and speech signals to get message,whichcan improve the recognition rate greatly.From a certain perspective,lip-reading is a branch of speech recognition,but they can be treated as two independent events Actually,computer lip-reading is one of the great signal,processing challenges (Lan,Richard Barry-John,2012).Comparing to speech recognition,lip-reading has a shorter history.The first lip- 2 Reading Assistant is the only online tool that uses speechrecognition tocorrect and support studentsas they read aloud. 8/19Research Status of Human-Computer Interaction 8 / 19 Nowadays, thanks to the almost maturity of technology, speech recognition systems are being applied in a large number of fields, such as commerce, education, and entertainment.
