British English pronunciation will also pass if it accurately matches the target phonetic symbol. The acceptable range is not divided into American English and British English.
Model audio uses American English or the audio specified for textbook-aligned learning materials. Please distinguish the type of model audio from the pronunciation evaluation criteria.
Even for the same word, you may not pass if you pronounce it according to a phonetic symbol different from the target one. For details, see “Model audio and English pronunciation evaluation criteria.”
