iPA Phonetics: Multimodal iOS application for phonetics instruction and practice

iPA Phonetics is an iOS application based on the Laryngeal Articulator Model that illustrates voice qualities, vowel qualities, and consonant production with video/audio of articulations in the oral vocal tract and laryngoscopic video/audio and ultrasound images of the laryngeal vocal tract. The Consonant Chart is an expanded version of the 2005 IPA chart; the replay speed of consonant and vowel sounds can be controlled; and random consonants and vowels can be generated for recognition practice. This selfcontained app for Apple iOS mobile electronic devices gives users the ability to access and compare phonetic symbols and sounds together with detailed articulatory production correlates. The app is free on the Apple Store, intended to introduce the general public as well as specialized users of IPA symbolization, via iPad/iPhone technology, to the auditory inventory of possible speech sounds of the languages of the world and to how each sound is physically articulated.
