Speaking through a canEverytime we think about learning a new language, the same topics come to our mind: grammar, vocabulary, reading, writing, pronunciation… but we never wonder how we learnt our mother tongue in the first place.

The answer to that question is very simple: “because we can”. Humans have the physical tools to do it. We just need to introduce the specific code to make the machine work.

Today, we are going to learn how our body is perfectly prepared to speak any language.

El aparato fonador (vocal apparatus) is the group of organs that produces and increases the sounds we generate when we speak.There are 3 different groups:

  • La cavidad infraglótica (glottic cavity): it’s mainly made up of los pulmones (the lungs), los bronquios (bronchial tubes) and la tráquea (trachea or windpipe). These are responsible for the breathing stage.
  • La cavidad glótica (glottic cavity): la laringe (the larynx), las cuerdas vocales (the vocal cords), and los resonadores (the resonators) are part of this group. Phonation starts here.
  • La cavidad supraglótica (supraglottic cavity): here we find el paladar (the palate), la lengua (the tongue), los dientes (the teeth), los labios (the lips) and la glotis (glottis). They produce the articulation.

All these organs take part in the four stages of the speaking process:

  1. Fase de respiración (breathing stage): the air from los pulmones will be propeled by el diafragma (the diaphragm). It will give pressure to the breath stream.
  1. Fase de fonación (phonation stage): the expiratory air stream from los pulmones goes up through la tráquea to la laringe, where las cuerdas vocales produce a vibration.
  1. Fase de resonancia (resonation stage): the voice from the phonation stage is weak. That’s why los resonadores amplify and modify it. The sound comes to la faringe (pharynx), la nariz (nose) and la boca (mouth).
  1. Fase de articulación (articulation stage): depending on the movements of the articulators (labios, dientes, lengua, el paladar…), the sound will change.

That’s how the human voice is produced. All of these medical and anatomical concepts are included in our Medical Spanish Course.
