Mumbling is the habit of speaking with insufficient mouth opening, reduced volume, and swallowed word endings. It is rarely a deliberate choice and usually the result of years of casual speaking habits combined with social anxiety about being too loud or taking up too much space. It can be changed with specific practice.
WHAT TO LOOK FOR
Jaw opening exercise
The most common cause of mumbling is insufficient jaw movement. Practise speaking with exaggerated jaw opening on every sentence. It will feel extreme but sound clear and natural. Reduce the exaggeration until you find the level that is both comfortable and clear.
Consonant clarity drills
Practise pairs of consonant sounds that are commonly swallowed: p-b, t-d, k-g, f-v. Say them distinctly in isolation and then in sentences. Clear consonants are the foundation of clear, unmumbled speech.
Volume increase habit
Mumbling is often as much about volume as articulation. Speak at a volume that requires zero effort from your listener to hear you. If you have a habit of speaking quietly, deliberately increase your baseline volume and sustain it through full sentences.
TLDR:Use your Lucy sessions to practice speaking at full clarity. Open your mouth deliberately, finish your word endings, and speak at a volume that requires no effort from the listener. Real-time conversation with Lucy gives you immediate context in which to build these habits.

Record yourself speaking and listen back for the specific words or sounds that are most mumbled. Target those sounds in your next practice session. Specific targeted practice is more efficient than general volume or articulation work.
