Let phone users with web dialog - VoiceXML brings web access to new concepts
2004/04/09
With the rapid development of Internet technology, the information stored by the Internet and the services provided by the Internet are increasing, and people's lives and work methods are changed. However, the Internet has long been detached from public telephone networks with many users, making China's nine times a computer user's telephone users who cannot use the phone to enjoy the rich and colorful information and services provided by the Internet. Although the number of computers is constantly increasing, the number of computer users will not approach the number of telephone users in a considerable period of time. How to make such a huge telephone user group can also access the Internet, is a challenge and business opportunities in front of the relevant industry operators, content providers, and service providers. VoiceXML speech extension description language introduction, bringing hope to the Internet and public telephone network, allowing Internet information to flow to the telephone network in a voice, so that the Internet service can extend to telephone users. VoiceXML 1.0 is a telephone voice application system standard that is jointly launched by AT & T, IBM, Lucent Technology Technologies, and Motorola through the W3C Association in 2000. This standard thoroughly changed the development model and application range of traditional CTI (computer telephone integration system), so that public telephone network, voice processing technology, and the Internet organically combined. VoiceXML 1.0 has been supported by many manufacturers in the relevant industry in the world, and the product based on VoiceXML standard is constantly flocked to the market. At present, people are very familiar with HTML, similar to HTML used for web pages markers, VoiceXML is a voice-extensible tag language that is developed for voice applications. VoiceXML makes the combination of public telephone network and the Internet in three aspects: the use of voice browsers, information sharing of Internet and public telephone networks, and the development of voice application systems similar to the web page development process. 1. The emergence of voice browser Web browser (IE and Netscape) has driven the development of the Internet, bringing new changes to people's daily life and work. The web browser is communicated with text information through the computer terminal. Similarly, the VoiceXML voice browser communicates with voice information through telephone terminals. The implementation of VoiceXML voice browsing is primarily depends on voice processing technology and voice browsing techniques similar to web browsing technology. With a voiceXML voice browser, telephone users can use voice inputs and traditional buttons input methods to communicate with voice applications via phone and voice application systems with voice application. In this process, speech processing technology such as speech recognition (conversion of speech to text) and voice synthesis (text-to-speech conversion) play an important role. The rise and development of voice processing technology has been a long time. However, speech recognition and speech synthesis technique really start to go to actual applications or time in the last two years to three years. Voice technology is one of the key technologies that enable telephone users to use natural languages and web conversations. The speech recognition function enables the application system to identify the voice input of the telephone user, convert it into text for computer processing. In recent years, speech recognition technology has a growing development, and the best speech recognition system can reach the identification of natural language within a certain range. Although the application of the technical limitations and the characteristics of Chinese multi-dialect multi-tone makes the application of the speech recognition system are restricted, speech recognition technology is still constantly entering people's daily life, people also start to accept speech. The telephone voice system is communicated. Voice synthesis technology is more mature in practical applications relative to speech recognition techniques. Currently, a better voice synthesis system can have achieved better understanding and naturalness. Voice synthesis technology is the key to the flow of Internet information to public telephone network. For example, the text information provided in the voice portal station, such as timely news, etc., can use speech synthesis to convert it into a speech format and play it to the user via a telephone. Getting rid of the phone user can only listen to the traditional use of a pre-recorded recording. In addition to speech processing technology, VoiceXML voice browsing technology is also the key to telephone voice application systems. Similar to HTML, VoiceXML makes the telephone voice application system depending on the status of the dialog and the business needs of the specific application domain, turn the dialog process to the next internet URI link definition dialog process.
In the definition of the dialog process, not only the URI files on the internet can be accessed, but also access to the Internet and the LAN. The introduction of web browsing technologies makes the telephone voice application system organically combined with the Internet to make the phone voice application system to the telephone user in an open manner. VoiceXML voice browser uses Internet browsing technology to integrate voice processing technology and Internet technology, which greatly expands the application range of the telephone voice system, and also makes the Internet information and services to the telephone user group, so that the Internet won more user. 2. The Internet and public telephone network information sharing the Internet and the public telephone network for a long time for separation. With the rapid development of the Internet and the rapid increase in Internet information, the huge telephone user groups (including fixed-line users and mobile phone users) accesses Internet information and enjoy the Internet provided by the Internet are becoming more and more important. The VoiceXML standard is undoubtedly an excellent business opportunity to Internet service providers, operators, and content providers. VoiceXML browsing technology is open, VoiceXML browser can browse any disclosed files and data on the Internet, which allows telephone users to access Internet information by means of speech processing technology. For example, telephone users can listen to online news through the VoiceXML browser, query online database, download and listen to voice files (such as music, songs, message, voice mail, etc.). Thus, the use of VoiceXML browsing technology, allowing the Internet to naturally flow to the public telephone network. VoiceXML browsing technology not only allows telephone users to access the Internet, but also pass public telephone network information to the Internet. The public telephone network information and Internet information are different in that the former is dynamic, mainly speech, and disappears with the end of the phone dialog. However, in some telephone voice application systems, you need to save the information generated by the dialog to future access to a web browser. For example, the user's voice message and the conversation process can be transmitted to the Internet by email or file transfer. When this information is stored in the Internet, both Internet users and telephone users can access this information via a web browser and a VoiceXML browser. The introduction of VoiceXML browsing technology allows the Internet and public telephone networks to organically combine, so that the two network information can flow, so that the Internet and public telephone network reach information sharing. 3. The emergence of the development of the "voice web page", not only changed the use of the speech application system and the scope of use, but also brings new concepts and patterns to the voice application system development process, so that the development of voice application systems is actually The development of "speech web page". Traditional telephone voice system development is to use CTI (Computer Telephone Integration) technology to bring each system components such as voice cards or switches, organizations and integration. Developers often need to be familiar with underlying coding and in-depth understanding of the programming interfaces for hardware, they can build a telephone voice system. However, the use of the VoiceXML browser allows the phone application system developer from the cumbersome program details. The development of voice web pages does not need to understand each system constituent component, such as a programming interface such as voice recognition, speech synthesis, and voice card / switches. Similar to the development of web pages, developers of voice web pages only need to write a VoiceXML script, allowing developers to put energy on the business process of the application system. The development process of voice web pages is simple and fast. Developers do not need to master advanced computer programming languages such as C / C or Java to develop a complete phonetic application system. And the system developed is often more open than the system developed by traditional development methods, more powerful. The development of voice web pages is lower for developers, and the development cycle is greatly reduced, thereby greatly reduced development cost. The developed application system has high maintenanceability, portability, scalability, and reusability. Below is an easy example of a VoiceXML. When the user is turned on with the phone voice system, it will hear the voice synthesis prompt "" Hello! Please select the service we provide for you: ".
When the user said the "stock market", the voice browser (input via speech recognition function recognition user input) will turn the dialog to another VoiceXML script file stocks.vxml. The Stocks.vxml script file is a voice web page that provides a stock market-related service. Obviously, based on the development of the VoiceXML phone voice application system, the traditional CTI development model is abandoned, so that the development process is similar to the development process of the web page. The development process of the VoiceXML phone voice application system is the development process of voice web pages. The emergence of VoiceXML has enabled the Internet and public telephone network to integrate, so that telephone users can communicate with web pages, allow public telephone networks and Internet information to enable new concepts of voice web pages to replace the traditional text browsing. The public telephone network has become an extension of the Internet, providing a rare opportunity for Internet contentors, operators, and service providers. Currently, VoiceXML has just been risings in developed countries and quickly gains support and identity in related industries. China is also in the development of VoiceXML related products, Shenzhen Huazai Technology Co., Ltd. has taken the lead in launching the VoiceXML voice gateway vgateway to all types of virtual or self-built websites, and supports ASP, PHP, CGI , JavaScrip, etc. scripting languages. As is as simple as writing HTML language, it will guide ordinary website technology innovation, unveil the new chapter of the voice website!
