I don't think a lot of people consider their speaking voice on a regular basis, but how we carry our vocal chords (pitch, amount of vocal fry, placement, etc) is just as much a self expression as the clothes we wear. People assume so many things about you based on your voice, and they change over time.
Before a big meeting or a social engagement or just as a morning routine, consider starting your day with some light vocal exercises to make you sound confident & clear. turns out, ppl will want to listen to you more!!!
