发音语音学 是语音学的分支。研究发音语音学的语音学家希望能翔实记载人类发出语音的过程，以了解发音孔道中各个器官（称为发音器官，包括舌头、嘴唇、牙齿、下颚、硬颚、软颚）是如何协调运作以发出某个语音。

为了了解语音产生的过程，通常必须使用实验方法，因此本学门也常被归类为实验语言学的一支。例如，为了要了解在产生某个语音时，舌头与硬颚碰触的范围为何，实验者会采取电子硬颚图(electropalatography, EPG)的方式来测量。电子硬颚图的实验过程是，在受测者口中装上特制的人工假颚，假颚上设备了许多电极。当受测者发出某个特定语音时，这些电极就可以侦测到所需的信息，包括假颚有哪些部位与舌头接触以及这些接触点在时间维度上的变化等。

The field of articulatory phonetics is a subfield of phonetics. In studying articulation, phoneticians explain how humans produce speech sounds via the interaction of different physiological structures.

Generally, articulatory phonetics is concerned with the transformation of aerodynamic energy into acoustic energy. Aerodynamic energy refers to the airflow through the vocal tract. Its potential form is air pressure; its kinetic form is the actual dynamic airflow. Acoustic energy is variation in the air pressure that can be represented as sound waves, which are then perceived by the human auditory system as sound.
