Abstract：
OBJECTIVE: Speech perception that takes place in the cochlea is involved in the process of language. The objective was to describe the findings in transient otoacoustic emissions in children with language problems before and after 6 months of speech therapy.
METHODS: There were 17 children with language problems between 3 and 6 years of age diagnosed with anarthric language delay (expressive and mixed language disorder). They underwent medical history, otoscopy, intelligence level testing, initial language test, tympanometry of 226Hz, audiometry and transient otoacoustic emission test.
RESULTS: We evaluated the 17 patients again after 6 months of attending speech therapy. The percentage of overall reproducibility of transient otoacoustic emissions in both ears was adequate to perform frequency analysis. We found a statistically significant difference (P≤0.01) in the frequency of 1kHz reproducibility when comparing results before and after therapy in the right ear. There was a significant difference (P≤0.05) when comparing the results of audiometry at frequencies of 0.5, 1.5, 2, 4 and 8kHz in the right ear and a highly significant difference (P=0.001) in the frequency of 3kHz in the left ear.
CONCLUSIONS: The analysis of sound through the cochlea is involved in the process of language acquisition. A poor processing of speech sounds in the peripheral system could result in poor processing at the central level. Consequently, it is important to consider our results when making a diagnosis and carrying out rehabilitation treatment in children with language disorders.

摘要：
目的：发生在耳蜗中的言语感知与语言过程有关。目的是描述言语治疗6个月前后有语言问题的儿童的瞬时耳声发射的发现。
方法：有17名3至6岁的语言问题儿童被诊断为无语言障碍（表达性和混合性语言障碍）。他们有病史,耳镜检查,智能水平测试，初始语言测试，226Hz的鼓室测量,听力测量和瞬态耳声发射测试。
结果：我们在主治语音治疗6个月后再次评估了17例患者。双耳瞬态耳声发射的总体再现性百分比足以进行频率分析。当比较右耳治疗前后的结果时，我们发现1kHz再现性的频率存在统计学上的显着差异（P≤0.01）。比较右耳0.5、1.5、2、4和8kHz频率的测听结果，差异有统计学意义（P≤0.05），左耳3kHz频率的测听结果差异有统计学意义（P=0.001）。
结论：通过耳蜗的声音分析涉及语言习得过程。外围系统中语音声音的不良处理可能导致中央级别的不良处理。因此,在对语言障碍儿童进行诊断和进行康复治疗时，重要的是要考虑我们的结果。
