How did the work of claude-nicolas ledoux reflect a desire for architecture parlante?

The way how work of Claude-Nicolas Ledoux reflect a desire for architecture parlante (which also means 'talking architecture') is that in his works architecture expresses its direct meanings through its structure and form, the way how it is done bestly shows the actual character of the work. He thought that this way must create both clarity and people's understanding of aesthetics than through symbolistic way.
