This resource is a collection of interactive International Phonetic Alphabet (IPA) charts, with clickable IPA symbols to let you hear a recording of the sound. It was inspired by a similar chart at ipachart.com, and has been re-created as a set of IPA charts, customized to cover the phonemic inventories of the most frequent languages of students in The Ohio State University's ESL Spoken English Program (as of 2018).
These charts have the advantage of including a language's entire phonemic inventory in the main consonant and vowel charts, rather than having some of the phones appearing in supplemental charts at the bottom of the page, or not appearing at all if they involve a suprasegmental articulation (such as aspiration).
These charts also have the advantage of removing the visual clutter of numerous sounds that are not in a given language's phonemic inventory. Thus, by opening different charts in different tabs and toggling between them, an ESL/EFL teacher or student can quickly view the phones common to multiple languages, and those that are in one phonemic inventory but not another.
Phonemes that are part of multiple languages are linked to the same sound file. This may result in slight phonetic divergences from typical speaker pronunciations. For example, both English and Korean have voiceless and aspirated voiceless stops. In English, the difference is not (completely) phonemic, but in Korean, it is. Possibly as a result, the difference in voice onset time between aspirated and non-aspirated stops is less in English than in Korean. Even so, the sounds recorded (by an English speaker) are used for both English and Korean.
Phonemic inventories were taken from various online resources, including the native phonetic inventory page of George Mason University's Speech Accent Archive, and resources linked to the Phonemic Inventories Across Languages page on the American Speech-Language-Hearing Association website.
