關於此聲音
A 32-second spoken clip in Portuguese where a voice repeats a short line identifying the recording as a demonstration audio. The repetition gives it a plain, check-the-playback feeling rather than a performance, making the phrase easy to recognise even for listeners who only know a few Portuguese words.
