Chapter Summary
We normally
speak while breathing out. Air passing out of the lungs must go through the
larynx, where its flow is controlled by the vocal folds. They may be open
(as for breathing, and for voiceless sounds), closed (for a glottal stop),
or vibrating (producing voice). Voicing makes a distinction between
consonants such as [v] (voiced) and [f] (voiceless), and this is utilised in
many languages of the world. Voiced sounds have complex periodic waveforms,
and voicing is the only source of periodic energy in speech |
