What are the Stages in the Production of Speech?

Speech creation is a multi-stage, intricate process that necessitates the synchronization of several physiological and anatomical systems. Three basic steps may be used to generally classify the stages involved in speech production:

1. Respiration:


The process starts when air is inhaled through the mouth or nose. To force air into the lungs, the diaphragm contracts and the chest cavity enlarges.


As air is released from the lungs during speaking, a regulated exhalation takes place. The ribs and abdominal muscles aid in controlling airflow.

2. Phonation:

 • voice Cord Vibration:

Air from the lungs enters the trachea and travels to the larynx, which houses the voice cords. Sound is produced by the vocal cords vibrating as air flows through them. The length and tightness of the vocal chords affect the sound’s pitch.

  1. Articulation:

 • Formation of Speech Sounds:

As the sound travels through the vocal tract—which consists of the nasal, pharyngeal, and oral cavities—it is subsequently altered. Speech sounds are created by the movement of the tongue, lips, jaw, and other articulators.


The way the articulators are positioned affects the vocal tract’s resonant properties, which add to the uniqueness of each spoken sound.

The production of understandable speech depends on the synchronization of these processes. Additionally, the motor cortex and other relevant brain regions play a major role in the planning and regulation of speaking motions. Speech problems or disorders can result from impairments or abnormalities at any point in the speech production process.

Speech Organs

Several speech organs, commonly referred to as articulators, are used in the production of speech in order to shape and alter the airflow from the lungs into speech sounds. The primary speech organs used in speech production are as follows:

1. The respiratory system and lungs:


The airflow required to produce speech is provided by the lungs. Air enters the larynx through the trachea during exhalation.

2. Voice box, or larynx:

voice Cords:

 During exhale, air travels through the voice cords, which are housed in the larynx, causing them to vibrate. Pitch is influenced by this vibration, which generates the voice’s fundamental frequency.

3. Pharynx:

The pharynx serves as a muscular tube that joins the larynx to the nasal and oral canals. It influences resonance and the way the vocal chords make sound.

4. The oral cavity

Tongue: By shifting its location inside the mouth cavity, the tongue—a highly flexible and muscular organ—plays a critical role in producing sounds.

Lips: Certain speaking sounds are produced by movements of the lips. For instance, the lips are used to produce the sounds “p,” “b,” and “m”.

Jaw: The way the jaw moves affects the way spoken sounds are articulated by forming various mouth configurations.

5. Nasal Cavity:

Soft Palate (Velum):

 To regulate the amount of air that enters the nasal cavity, the soft palate can be elevated or lowered. mouth noises are produced when the soft palate is lifted, which directs airflow into the mouth cavity. It may be lowered, allowing some air to enter the nasal cavity and making nasal noises.

6. Teeth:


The way teeth are arranged can have an impact on how some speech sounds are articulated, especially those that involve contact or airflow limitation.

Intelligible speech can be formed and a variety of speech sounds can be produced thanks to the coordinated motions of these speech organs and the respiratory and neurological systems’ control. Speech problems or issues can result from any interference or impairment in these organs’ normal operation.
