Features of Internet voice interactive technology products

Today saw Google's blackboard, the legendary Google Chinese mobile phone voice search officially published in number second, users can use their own voice to interact with the mobile phone to find their own information needed.

The ability to talk to computers and other devices is one of the people's desire, the human has not satisfied with the current through the mouse, buttons and other means and equipment to interact, hope to be able to communicate with the device through the voice to use and control equipment. The most important thing in speech communication is speech recognition system. The most difficult and difficult to solve in the speech recognition system is the processing of the user's background noise and the user's pronunciation change , these two key if can break through will make the voice interaction this way to use in the more equipment and the environment.

Google Chinese voice search is first used on mobile devices, it is inevitable, because of its wide use of mobile phones and the development of voice chips, can solve the problem of user background noise to a certain extent, but for users to change the pronunciation (more than the dialect, using special syllables, etc.) this problem is not a good solution.

1. Voice Store forwarding
2. Discrete word recognition
3. Continuous speech recognition
4. Sound Information System
5. Speech generation

The deficiency of the form of speech interaction in relation to other forms of interaction:
Key issues in Voice interactive input
1. Increase the user's cognitive burden by interacting with the fingers
2. Susceptible to external noise interference
3. Encounter changes in user, environment, voice recognition will become very unstable

The main problems of voice interactive output

2. Speech belongs to short time memory, disappear faster, increase user's cognition, memory difficulty
3. Browsing and searching are more difficult

Although voice interaction has a lot of drawbacks, its great advantage is that it will occupy an important place in the way of future interaction. Want to have more and more use of voice interactive technology products appear, especially the Internet products.
