VI. Reading

1. Make a list of as many computer languages as you can think of.

2. Study the table, then answer the questions.

  1. What does VXML mean?

  2. Who created VoiceXML?

  3. When was it developed?

  4. What technologies does it use for input and output?

  5. What are the most suitable applications for VoiceXML?

  6. What do you think are the benefits of having a voice Web?

The VoiceXML language

Language

VXML or VoiceXML (Voice Extensible Markup Language)

Created by a working

group of 4 companies: AT&T, Lucent, Motorola and IBM in 2000

Characteristics

Based on the XML language for input, VoiceXML uses voice recognition. For output, it uses pre recorded audio content and speech synthesis (text-to-speech).

To access voice web first you dial its phone number, the call is received by a telephone server and the VoiceXML pages fetched via HTTP. Finally, you get the required information. A typical VoiceXML page could be 'sports.vxml'.

Uses

Used to create voice-user interfaces. Makes Internet content accessible via voice and phone. Instead of using a web browser on a PC, you use the telephone to access voice-equipped websites via a VoiceXML interpreter (a voice browser). Applications: 1. Voice portals (telephone services where you can hear information about sports, news, traffic, etc.) 2. Voice-enabled intranets 3. Voice e-commerce

4. Home appliances controlled by voice.

III. Grammar: The Passive

1. Study this information:

The passive is formed with the verb to be in the correct tense and the past participle of the main verb.

e.g. Instructions are processed by the CPU.

2. Complete these sentences with a suitable verb form.

  1. COBOL (use)………for business applications.

  2. Original programs (write)……… in a high-level language.

  3. All computer languages (must translate)………into binary commands.

  4. The ADA language (develop)………in 1979.

  5. In the 1970s, new languages such as LISP and PROLOG (design)………for research into Artificial Intelligence.

  6. A new version of TurboPascal (release)………just……….

  7. In the next century, computers (program)………in natural languages like English or French.

3. Read the passage and complete it with the verbs in the correct forms.

Visual BASIC is a programming language and an environment(1) …… (develop) by Microsoft in 1990. It (2) …… (use) to create applications for Windows operating systems.

The adjective 'Visual' refers to the technique used to create a graphical user interface. Instead of (5) …… (write) a lot of instructions to describe interface elements, you just (6) …… (add) pre-defined objects such as buttons and dialog boxes, which can (7) ……. (choose) from a toolbox.

It (8)…….. (take) only a few minutes to create a Visual BASIC program. Using the mouse, you simply (9) …... (drag) and drop controls (e.g. option buttons, text boxes, icons, menu bars, etc.) into the required position, and then define their colour, size and behaviour.

Thanks to its object-oriented philosophy and interactive nature, Visual BASIC (10) ………. (enable) the programmer to quickly create all sorts of applications from small system utilities to database programs and Internet server applications.
