A developer built Phonetic Formatter, an offline-first mobile app that uses the CMU Pronouncing Dictionary to batch-convert English text into IPA transcriptions with word-aligned formatting. The tool solves the pain of manual IPA transcription for linguistics teachers and ESL professionals by providing structured word-by-word output and direct DOCX/PDF export with compatible fonts.
