  2. Speech science - Wikipedia

    en.wikipedia.org/wiki/Speech_science

    The production of speech is a highly complex motor task that involves approximately 100 orofacial, laryngeal, pharyngeal, and respiratory muscles. [2] [3] Precise and expeditious timing of these muscles is essential for the production of temporally complex speech sounds, which are characterized by transitions as short as 10 ms between frequency bands [4] and an average speaking rate of ...

  3. Human voice - Wikipedia

    en.wikipedia.org/wiki/Human_voice

    The sound of each individual's voice is thought to be entirely unique [13] not only because of the actual shape and size of an individual's vocal cords but also due to the size and shape of the rest of that person's body, especially the vocal tract, and the manner in which the speech sounds are habitually formed and articulated. (It is this ...

  4. Vocal cords - Wikipedia

    en.wikipedia.org/wiki/Vocal_cords

    The vocal folds of children are much shorter than those of adult males and females. The difference in vocal fold length and thickness between males and females causes a difference in vocal pitch. Additionally, genetic factors cause variations between members of the same sex, with males' and females' voices being categorized into voice types.

  5. Tongue - Wikipedia

    en.wikipedia.org/wiki/Tongue

    The tongue is one of the primary articulators in the production of speech, and this is facilitated by both the extrinsic muscles that move the tongue and the intrinsic muscles that change its shape. Specifically, different vowels are articulated by changing the tongue's height and retraction to alter the resonant properties of the vocal tract .

  6. The medium is the message - Wikipedia

    en.wikipedia.org/wiki/The_medium_is_the_message

    For McLuhan, it was the medium itself that shaped and controlled "the scale and form of human association and action". [5] Taking the movie as an example, he argued that the way this medium played with conceptions of speed and time transformed "the world of sequence and connections into the world of creative configuration and structure".

  7. Phonation - Wikipedia

    en.wikipedia.org/wiki/Phonation

    Also, the existence of an optimal glottal shape for ease of phonation has been shown, at which the lung pressure required to initiate the vocal cord vibration is minimum. [4] This is modal voice, and is the normal state for vowels and sonorants in all the world's languages. However, the aperture of the arytenoid cartilages, and therefore the ...

  8. Manner of articulation - Wikipedia

    en.wikipedia.org/wiki/Manner_of_articulation

    Trills involve the vibration of one of the speech organs. Since trilling is a separate parameter from stricture, the two may be combined. Increasing the stricture of a typical trill results in a trilled fricative. Trilled affricates are also known. Nasal airflow may be added as an independent parameter to any speech sound.

  9. Articulatory phonetics - Wikipedia

    en.wikipedia.org/wiki/Articulatory_phonetics

    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. [a] Respiratory sounds can be produced by expelling air from the lungs. However, to vary the sound quality in ...
