The current study describes the collection of a new phonemically-balanced Spanish sentence resource, known as the Sharvard Corpus.
The resource contains 700 sentences inspired by the original English Harvard sentences along with speech recordings from a male and female native peninsular Spanish talker. Sentences each contain five keywords for scoring and are grouped into 70 lists of 10 sentences using an automatic phoneme-balancing procedure.
Twenty-three native Spanish listeners identified keywords in the Sharvard sentences in speech-shaped noise.
Psychometric functions for the Sharvard sentences indicate mean speech reception thresholds of -6.07 and -6.24 dB, and slopes of 10.53 and 11.03 percentage points per dB at the 50% keywords correct point for male and female talkers respectively.
The resulting open source collection of Spanish sentence material for speech perception testing is available online.
本研究描述了一种新的音素平衡的西班牙语句子资源——Sharvard语料库的收集情况。
该资源包含700个受原始英语哈佛句子启发的句子，以及来自西班牙本土半岛地区一男一女的语音录音。每个句子包含五个用于评分的关键词，并使用自动音素平衡程序分为70组，每组10个句子。
23名以西班牙语为母语的听众在语音噪声环境中识别Sharvard句子中的关键词。
Sharvard句子的心理测量函数表明，男性和女性说话者在50%关键词正确点处的平均言语接受阈值分别为-6.07 dB和-6.24 dB，斜率分别为每分贝10.53和11.03个百分点。
由此产生的用于言语感知测试的西班牙语句子材料的开源集合可在线获取。
