DECtalk Software In-Line Commands: Overview

DECtalk Software includes in-line commands. In this documentation, DECtalk Software in-line commands are referred to as commands. You can use these commands to perform simple in-line operations, such as changing the speaking rate or speaking voice while DECtalk Software is speaking. Commands are inserted directly into the ASCII text that is sent to the synthesizer. The following table lists the DECtalk Software in-line commands and their associated functions.

With phoneme interpretation, it is possible to control intonation and stress and to create special effects, such as singing. These symbols and special effects can be added into the ASCII text stream.

For more information, click here to see the Phoneme Interpretation command.

When you use several commands together, they might interact with each other and affect the output. If incorrect syntax is used in a command, the right bracket ( ] ) is ignored because it might be considered part of the illegal string. To avoid this situation, insert an extra right bracket ( ] ) in the command and use the Error command to enable the speaking of errors.

Unique abbreviations of command names and option names work reliably. However, 4-character abbreviations will be supported for future releases. A character abbreviation of less-than-four characters that works in the current release may not be unique in a future release. Only 4-character abbreviations, as shown in this documentation, will be supported for valid commands in future releases.
