Is the Portuguese version of the passage ‘The North Wind and the Sun’ phonetically balanced?

There is no standard phonetically balanced short passage for Portuguese research and clinical practice. This paper presents results of a novel analysis of ‘The North Wind and the Sun’ (NWS) passage that aims to determine if it is phonetically balanced for European Portuguese (EP) and Brazilian Portuguese (BP), based on new transcriptions resulting from algorithms developed for grapheme–phone transcription in these two varieties of Portuguese. These algorithms (based on standard EP and Sao Paulo BP varieties) are the same as those used to collect the frequency data, which is central to determining if a text is phonetically balanced. Results showed that neither transcription violates phonotactic rules, i.e. permissible combinations of speech sounds. The NWS is not phonetically balanced for BP if the phonemes are considered individually but is evenly distributed in terms of manner of articulation. The EP version of the NWS passage is a phonetically balanced text for EP.
