Realization Of Intelligent Voice Assistant System Based On Intelligent Voice Interactive Technology

With the arrival of mobile Internet, mobile terminal equipment are increasingly being applied to people’s daily life, especially the application of intelligent mobile phone. The intelligent mobile phone makes people entertainment and surf the internet convenient, but with the mobile phone function enhancement, the interaction complexity of people and the intelligent mobile phone is increasing. In recent years, the speech recognition technology has been applied to intelligent mobile phone, people can use voice call or send text messages; people also can listen the incoming call and new information, the user does not need to transfer the eyes can be completed answering and checking message.The phone voice applications generally USES multiple conversational voice confirmation, which does not reduce the operation time in actually, and multiple of interaction makes the recognition rate lower. C umbersome voice interaction not only failed to reflect voice operation efficiency, but also affect the operability of mobile terminal voice interaction system. O f the mobile terminal environment this particular scenario, this paper puts forward a voice interaction scheme, the user through a simple voice command and control of smart phones, such as phone calls, text messaging, listening to music, check the weather, such as mobile terminal also according to the need of the content of the feedback given in the form of the voice prompt. Voice interaction in the process of users do not need to transfer the eyes C had look at the screen, can manipulation of the mobile phone with a voice command, abandoned the tedious multi-step dialogue, through the speech listening to query information. Compared with the traditional interface interaction and conversational voice interaction for many times, greatly improve the intelligent terminal can be convenience. At the same time, based on the hkust xunfei sound technology on the Android platform to realize the intelligent voice phone assistant software, the system is mainly composed of speech interactive service module, voice recognition module, speech synthesis module, audio mission control module, voice interaction services is responsible for calling speech, speech synthesis module calls a voice command from the speech recognition module to the user, which can identify and call the voice prompt to broadcast speech synthesis module, at the same time, the result will be sent to the corresponding treatment processes; Audio mission control module audio surveillance task at any time, and get the current audio task change, when a new task for audio, according to audio task priority decision whether to perform application in response to user action, between the speech application can orderly coordination work, to avoid interferences with the recognition of speech interaction.System test pass on the Android platform, stable running, convenient voice interaction. Under the environment of clean speech system recognition rate reached 90%, at low vehicle noise to drive close, recognition rate is above 85%, a voice interaction time control within 5 seconds, implements the combination of voice technology and intelligent terminal efficiency.
