Editing user dictionaries can be challenging especially with the L&H phoneme format.

A new editing surface has been added to Chant Developer Workbench to edit user dictionary text format and L&H phonemes.

The intelliprompt editor has been updated with dictionary text format syntax to assist with text editing and for inserting L&H phonemes in pronunciations.

For example, the editor will automatically generate default pronunciation phonemes after typing the word followed by double backslash:
