What are the three types of vocal registries?


A vocal register refers to the different modes of vibration of the vocal folds for phonation. There are three types of vocal registries:

1. The model register, or modal phonation, is the first type of vocal register. We use the model register in our daily speech. The speech-language therapist works most often with clients who have model register disorders.

2. The glottal fry, or pulse register or Strohbass ("straw base"), is the second type of vocal register. This register produces a voice that has a crackly quality. If the person's voice is rough and low in pitch, he or she may have a respiratory illness.

3. The falsetto is the third and highest phonation register. The vocal folds lengthen and become very thin, producing vocal sounds that are higher than the normal range. Falsetto requires increased vocal fold tension.
