摘　　要：分别于2011年5月和2012年5月对笼养和野生画眉鸣唱进行了声音采集,利用Adobe Audition软件对唱句进行划分后,再用Praat软件对笼养和野生画眉鸣唱频谱特征、音节类型、音素特征等进行了分析.结果发现:笼养画眉音素数平均为3.32±1.84,持续时间为1.02±0.73s,最长时间可达2.88s,间隔时间为0.26±0.17s,频率范围为0.13～0.38kHz;野生画眉音素数平均为2.35±1.66,持续时间为0.55±0.44s,最长时间可达2.43s,间隔时间为0.22±0.16s,频率范围为0.16～0.35kHz.笼养画眉音素类型以没有弯转的B类型为主,而野生画眉以有弯转(弯转度超过180°)的A类型为主;两类画眉共有75种音节,其中有9.33%的为笼养与野生画眉共享音节.结果表明画眉在笼养环境下,鸣唱会越发变得单调、重复且不弯转.Songs of the feral and the caged Garrulax canorux were collected in Mays of 2011 and 2012,the ballad was diflerentiated used the Adobe Audition,and then the spectrogram characters,syllable types and phoneme features were compared between the ferals and the caged birds used Praat software.The results indicate that the number of the phonemes is 3.32±1.84;the time of duration is 1.02±0.73s;the longest time is 2.88s;the time interval is 0.26±0.17s and sound frequency ranged 0.13±0.15 kHz to 0.38±0.05 kHz of the caged birds,while those of the ferals is 2.35±1.66,0.55±0.44s,2.43s,0.22±0.16s and 0.16±0.03 kHz to 0.35±0.05 kHz respectively.The caged ones have the phoneme type which is lack of turns（phoneme type B） while the ferals possesse those which is charactered by turns and the curvature exceeded 180°（phoneme type B）.There are 75 kinds syllabics of Garrulax canorux,of which 9.33 percent are the common of the caged and the feral ones.The results show that in closed surroundings,the sing of Garrulax canorux would become monotonous,repeated,and the degree of sweetness and mildly turned lower.
