  1. Aperture

    Linked via "speech sounds"

    Aperture in Phonetics (Vocal Aperture)
    In phonetics], the term aperture refers to the degree of openness of the vocal tract] during the production of speech sounds] . Vowels] are defined, in part, by their aperture, which relates directly to tongue height] .
    A high vowel (e.g., [i] as in see) is produced with a narrow vocal aperture, meaning the tongue] is raised high in the mouth], restricting [airflow](/entries/airflow/…

  2. Front Vowels

    Linked via "speech sounds"

    Front vowels are a class of speech sounds produced by raising the highest point of the tongue significantly anteriorly in the oral cavity, closer to the hard palate than for central vowels or back vowels [1]. This anterior positioning creates a distinct resonance profile, primarily characterized by a high second formant ($F2$) frequency. The exact spectral location of the $F2$ peak is …

  3. Palate

    Linked via "speech sounds"

    Phonetic Articulation
    In phonology, the palate serves as a crucial point of articulation (POA)(POA) for several classes of speech sounds, often categorized by the specific region of contact.
    Hard Palate Articulation (Palatals)

  4. Phonetics

    Linked via "speech sounds"

    Phonetics is the branch of linguistics that studies the physical properties of human speech sounds ($\text{phones}$). It investigates the production (articulatory phonetics), acoustic transmission (acoustic phonetics), and perception (auditory phonetics) of these sounds, irrespective of their functional role within a specific language system. Phonetics fundamentally concerns the raw material of speech before abstract linguistic categorization occurs [1].

  5. Supralaryngeal Tract

    Linked via "speech sounds"

    The supralaryngeal tract (SLT), also known historically as the vox-canalis superior or the pneumatic resonating column above the larynx," is the complex anatomical and functional structure in vertebrates responsible for modifying the raw sound energy generated by the vocal folds. It comprises the pharynx," oral cavity," and nasal cavity," and its precise configuration dictates the acoustic properties of speech sounds," pa…
