听力正常学龄前儿童语音发育规律研究

目的:初步探讨3～5岁听力正常儿童语音发育规律.方法:在建立汉语普通话3～5岁儿童日常生活口语词库的基础上,将词库中的单音节词分解成拼音音节及音素,计算字频、音素音节出现频率,并与成人组进行比较.结果:3～5岁儿童组口语词汇中出现全部汉语普通话所包括的音位,经独立样本t检验,与成人组言语中音位分布和频率分布差异无统计学意义.3岁组口语中出现音节323个,占成人音节总数的81.8%,4～5岁组出现369个,占93.4%.结论:3岁儿童言语中出现的音位分布规律和频率高低均与成人类似,提示此时儿童已基本完成言语发育中语音系统水平的发育.

The phonetic development of normal-hearing pre-school children

Objective:To collect the daily speech materials and to discuss the speech development of normal-hearing pre-school children.Method:Based on the database of daily speech materials of children who are 3 to 5 years old,from separate monosyllabic word to syllable,analysis the frequency of words and compare them with adults.Result:In the spoken words of children who are 3 to 5 years old,we can find all Mandarin phonemes.With independent sample t test,it was shown that there is no significant difference in the distributing of phonemes between children and adults.Conclusion:Children who are 3 years old have developed the phonetic system of the language basically.
