在怀孕的绵羊子宫内记录的语音刺激的可懂度确定知觉使用一组未经训练的法官。母羊的子宫内声音环境旨在模拟孕妇的声音环境。两个单独的列表，一个有意义的和一个无意义的语音刺激，通过扬声器传递到母羊的一侧，并同时记录与空气麦克风位于15厘米从侧翼和水听器先前缝合到胎儿的颈部。从这些录音中产生的感知测试磁带被播放给102名法官。在空气中记录的音素的清晰度显着大于从子宫记录的音素的清晰度。从子宫内记录的男性说话者的声音比女性说话者的声音更容易理解，但在空气中记录的声音却不是这样。对子宫内外录音的特征信息传输的分析表明，发声信息在子宫内比位置或方式信息更好地传输。
The intelligibility of speech stimuli recorded within the uterus of a pregnant sheep was determined perceptually using a group of untrained judges. The intrauterine sound environment of the ewe was intended to simulate that of a pregnant woman. Two separate lists, one of meaningful and one of nonmeaningful speech stimuli, were delivered through a loudspeaker to the side of the ewe and were simultaneously recorded with an air microphone located 15 cm from the flank and with a hydrophone previously sutured to the neck of the fetus. Perceptual test tapes generated from these recordings were played to 102 judges. The intelligibility of the phonemes recorded in the air was significantly greater than the intelligibility of phonemes recorded from the uterus. A male talker's voice was more intelligible than a female talker's voice when recorded from within the uterus, but not so when recorded in the air. An analysis of the feature information transmission from recordings inside and outside the uterus revealed that voicing information is better transmitted in utero than place or manner information.
