Talking and singing sound different from one another, but anatomically, what is really the difference?
Your speaking and singing voice are created from the same exact anatomical structures. The respiratory system (lungs diaphragm and abdominal muscles), laryngeal mechanism (vocal folds, laryngeal cartilages, muscles and nerves) and the supraglottic tract (the spaces above the vocal folds, including the back of your throat, mouth, nasal passages and sinus cavities) all work to produce the beautiful sounds you make. Speaking doesn’t require as much airflow (breath) as singing, but you still need to support the speaking voice. Singing involves the utilization of more of the supraglottic spaces for resonance, and the vowels are prolonged. Otherwise…they are almost identical. Just a note…your speaking and singing voice should sound almost identical in your speaking voice pitch range.
