Test phrases.

Each test phrase was selected for a unique sound focus, which was repeated three times in the sentence. These sounds could be categorized by speech category, including “plosives” which require a buildup of air to correctly articulate the sound, and “fricatives” which require the friction of breath in a narrow opening.每条测试短语均围绕特定语音焦点选取，且该焦点语音在句中重复出现三次。此类语音可按语音类别分类，包括需通过蓄积气流以准确发声的爆破音（plosives），以及需通过狭窄声道气流摩擦产生声音的擦音（fricatives）。
