Document Summary
Phonetic alphabet: a system of transcription which represents each speech sound with a single symbol and each symbol with a single speech sound. Phonetic transcription is a one-to-one correspondence between sounds and symbols. This eliminates the ambiguity of the sound-symbol variations within a language or across languages. Air is forced from the lungs by means of the pulmonic egressive airstream mechanism; air pushed out from the lungs. The vocal tract includes the larynx (voice box), the pharynx (the throat), the oral cavity (the mouth), and the nasal cavity. Into the oral cavity or the nasal cavity. Consonants: produced by obstructing or significantly restricting the air that flows from the lungs. Vowels: produced by at most only a slight narrowing in the vocal tract, allowing the air to flow freely through the oral (or nasal) cavity. Distinctive features: enables us to distinguish one phone from another. Some sounds are distinguished by the vibration of the vocal cords.
