Hääldusorganid, also known as speech organs, are the parts of the body used to produce speech sounds. These organs work together in a complex coordinated system to create the vast array of sounds that make up human language. The primary organs involved are located in the vocal tract, which extends from the lungs to the lips.

The process begins with the lungs, which provide the airflow necessary for speech. This air passes through the larynx, located in the throat. Within the larynx are the vocal cords, which can vibrate or be held open to produce voiced or unvoiced sounds respectively. The shape and tension of the vocal cords determine the pitch and quality of the voice.

Above the larynx, the airflow is further shaped by the pharynx, oral cavity, and nasal cavity. The tongue is a crucial articulator, capable of moving into many different positions to alter the shape of the oral cavity. Different parts of the tongue, such as the tip, blade, and back, interact with other parts of the mouth like the teeth, alveolar ridge, and palate.

Other important speech organs include the lips, which can be rounded, spread, or brought together to create various sounds. The teeth and the alveolar ridge (the bony ridge behind the upper teeth) are also important points of articulation. The soft palate, or velum, at the back of the roof of the mouth can be raised to block air from entering the nasal cavity, producing oral sounds, or lowered to allow air to pass through the nose, producing nasal sounds. The hard palate, the bony front part of the roof of the mouth, also plays a role in shaping sound.

Together, these organs form a dynamic system that allows humans to produce spoken language.
