# Inserting DECtalk Software In-Line Commands (Syntax Rules)

Rules for DECtalk Software In-line Command Syntax

Legend
Ê | Enclose every command within brackets.
Ë | Some commands have an alternate command to simplify input. Here the :name command and its argument Betty can be replaced by the alternate command :nb.
Ì | Begin every command with a colon.
Í | Separate each command name and its option or parameter from the command name text by a valid word boundary marker. The valid word boundary markers are a space and a tab. A space is used here.
Î | Include several options and parameters within the same brackets if the command allows more than one option and parameter. In this example, the option and parameter group ing modifies the [:dv] command.
Ï | If you give two conflicting commands, DECtalk Software uses the last command in the sequence. In this example, DECtalk Software uses Pauls voice.
Ð | If you enable phoneme interpretation by using the [:phoneme arpabet speak on] command, you can include phonetic spelling for text-to-speech synthesis. The phonetic spelling replaces the actual spelling and is enclosed within brackets. In this example, the phonetic spelling of word really (r iyl iy) is included.
