The term "open vowel" is used in phonetics to describe a vowel sound that is produced with an open jaw and mouth. In IPA phonetic transcription, it is written as /ˈoʊpən ˈvoʊəl/. The first syllable "oʊ" represents the diphthong produced by the combination of "o" and "ʊ" sounds. The second syllable "voʊəl" denotes the short "o" sound followed by a combination of "w" and "əl" sounds. By understanding this spelling, linguists can accurately describe this common vowel sound in speech analysis.
An open vowel is a term used in phonetics to describe a vowel sound that is produced with a relatively wide and unobstructed oral cavity, allowing for the unrestricted flow of air. This results in a sound that is perceived as having a relatively "open" quality.
In terms of articulation, an open vowel is produced by the tongue being positioned away from the roof of the mouth, allowing for a lower constriction. The lips may also be relatively open, contributing to the open quality of the vowel. As a result, the sound produced is characterized by a more open or extended resonance.
Open vowels are typically associated with greater intensity and longer duration compared to closed vowels. They are often described as being more sonorous and having a more prominent audibility due to the larger oral cavity and unimpeded airflow.
Examples of open vowels in English include /ɑː/, as in "car," /ɔː/, as in "aw," and /ɜː/, as in "bird." These vowels are characterized by their relatively open and unrestricted articulation, allowing for a more sonorous and resonant sound.
Overall, an open vowel refers to a vowel sound that is produced with a relatively wide and unobstructed oral cavity, resulting in a sound that is perceived as open or extended.
The word "open" comes from the Old English word "opan", which means "uncovered" or "not closed". It has roots in the Proto-Germanic language "opana" and the Proto-Indo-European root "op-" meaning "to work" or "operate". The term "vowel" comes from the Latin word "vocalis", meaning "vocal" or "relating to the voice". Therefore, the etymology of the term "open vowel" combines the concept of a vowel sound being pronounced with a relatively open vocal tract and the general term for a voiced speech sound.
