What practices can I use to work on a mumbling issue I seem to have developed?
Practice making clear, precise consonants.
Breathe deeply and speak with more energy.
Use humming and “nasty” sounds to access more resonance in your face and head, which will add brilliance and clarity to your voice.
You can also consider whether you are physically fatigued or unwell, or if your spirits are generally low.You might need to rest more, eat more healthy food, exercise more or spend time doing things you enjoy with people you love.
Ask yourself if you feel confident or if you have a strong sense of purpose.
Do you enjoy conversing?
Is humor part of your expression?
All of these are ingredients that can reduce mumbling, depending on what is causing it in the first place. You can also notice people who do not mumble and imitate them, noticing what changes in you when you do that.
