IPAKeys provides a keyboard with letters and symbols of the International Phonetic Alphabet (IPA, revised version of 2018). With the IPA keyboard you can type • Letters for consonants and vowels, • Diacritics for phonetic details, • Suprasegmentals for prosodic information, • Brackets used to set off IPA transcriptions. The arrangement and grouping of the keys reflect the usual grouping and arrangement of their corresponding phones. If applicable, as the keys of the keyboards provided by the system do, keys of the IPA keyboard reveal more characters and symbols when pressed and hold. P R I V A C Y   S T A T E M E N T I design my software following the principle to only collect, process, and store data that is actually needed for the software to serve its purpose. No single bit more than that. In German, the name of this principle is "Datensparsamkeit". A literal translation of this word is "data thrift". In effect, this means: • IPAKeys has no user accounts. IPAKeys will not ask you for personal data. • Data you enter in the IPAKeys app will not leave the app. In case of the provided keyboard, the characters you type will be passed to the operating system which will process them in order to, for example, insert them into a text field. • No personal data is collected or processed. • No user tracking of any kind is used.

toAllophones is a user-centrically designed app that allows users to transcribe English IPA Broad Transcriptions into Allophonic Transcriptions. Features: •⁠ ⁠Copy to Clipboard: Allows users to easily copy the result and paste it elsewhere, say your assignment. All in one click. •⁠ ⁠⁠Special Character Input: Saves your time finding them on the Internet. We know too well how frustrating it is to find them and copy and paste. Download our app and say goodbye to those moments. •⁠ ⁠⁠History: Find all the results you searched before. Surely, we don’t want to enter the IPA again if you’ve just searched it 2 minutes ago. You may delete past transcribed records at any time. •⁠ ⁠⁠Rules Applied: Easy reference to the allophonic rules used in your transcription. Sometimes you might have tried transcribing the IPA yourself, but it just doesn’t match with the answer and you wonder what rule you have forgot. Our app will help you review the allophonic rules for your own revision.
