Start with a comfortable pitch, not the highest pitch you can make
Raise the resonance slightly by speaking with a lighter, brighter tone
Use more forward placement in the mouth and face
Reduce chest resonance and avoid a heavy, deep sound
Shorten vocal weight by speaking with less pressure
Use smoother, more varied intonation
Keep the voice relaxed and avoid straining
Practice gentle breath support for steady airflow
Speak a little faster with clearer articulation
Use softer onset at the start of words
Listen to your own voice and adjust gradually
Record yourself and compare different settings
Practice daily in short sessions
Stop if you feel pain, hoarseness, or strain
Work with a qualified voice coach if possible
