Introduction

VoiceViewÒ is a communications technology that allows both voice and data communications to take place during the same telephone call. By integrating voice and data, an ordinary voice telephone call can include the exchange of data, graphics, or other digital information.

Integrated voice and data enhances what people can do during a telephone call by integrating the use of computers with person-to-person or person – to – voice-processing system communications. Computers add the viewing and manipulation of shared information to a normal telephone conversation.

Communications hardware implements the technology. A VoiceView-capable modem allows a user to take advantage of that technology. The modem can be part of a motherboard of a personal computer, part of an internal, PCMCIA, or external modem, or part of a multifunction card based on digital-signal-processing technology. Handheld computers, voice-response systems, screen phones, and other devices based on embedded software will also include technology and will communicate with VoiceView-capable personal computers.

Modem and voice-processing companies have already widely accepted VoiceView due to its attractive price, its ease of implementation, and its compatibility with existing data and telecommunications products. VoiceView works over a single analog telephone line or transparently across proprietary digital PBX or Key systems.

Starting in 1995, many computers running MicrosoftÒ WindowsÔ will be VoiceView-capable or will use VoiceView-enabled modems. This document describes how the developer of Windows applications can take advantage of integrated voice and data capabilities in those systems.
