诊儿之法听五声，聆音察理始能明，五声相应五藏病，五声不和五藏情，
心病声急多言笑，肺病声悲音不清，肝病声呼多狂叫，脾病声歌音颤轻，
肾病声呻长且细，五音昭着证分明，啼而不哭知腹痛，哭而不啼将作惊，
兹煎不安心烦热，嗄声声重感寒风，有余声雄多壮厉，不足声短怯而轻，
多言体热阳府证，懒语身冷阴藏形，狂言焦躁邪热盛，谵语神昏病热凶，
鸭声在喉音不出，直声无泪命将倾，虚实寒热从声别，闻而知之无遁情。
[注]
小儿之病，既观其色，又当细听其声，
盖笑，呼，歌，悲，呻，五声，内应心肝脾肺肾五藏也，
五声不和，则知五藏有病之情矣，
知心属火病，则声急喜笑，
肺属金病，则声悲音浊，
肝属木病，则声狂叫多呼，
脾属土病，则声颤轻如歌，
肾属水病，则其声长细如呻吟，
有声有泪声长曰哭，有声无泪声短曰啼，
如啼而不哭，则气不伸畅，主腹痛，
哭而不啼，则气急心烦，将成惊也，
兹煎不安者，乃心经内热，故燥躁不宁也，
嗄声音哑也，声重声浊也，此为外感风寒也，有余之证其气实，
故声雄大而壮厉，
不足之证其气虚，故声怯弱而轻短，
多言与身热皆阳也，阳主府，故曰阳府证也，
懒语与身凉皆阴也，阴主藏，故曰阴藏证也，
狂言焦躁者，邪热盛也，
神昏谵语者，热乘于心，故曰病热凶也，
鸭声声在喉中而哑，气将绝也，
直声声无回转而急，气将散也，二者俱为不治之证，
医者果能以此察之，
则知表里藏府寒热虚实诸病之情态无所遁矣。

The method of diagnosing pediatric diseases lies in listening to the five sounds; only by carefully hearing the sounds and analyzing their principles can one achieve clarity. The five sounds correspond to pathological conditions of the five Zang organs, and the disharmony of the five sounds reflects the state of the five Zang organs.
In Heart disease (Xin Bing), the voice is rapid with excessive talking and laughing; in Lung disease (Fei Bing), the voice is sorrowful and the tone is unclear; in Liver disease (Gan Bing), the voice involves calling out with much wild shouting; in Spleen disease (Pi Bing), the voice resembles singing with a trembling and light tone; in Kidney disease (Shen Bing), the voice is groaning, long, and thin. When these five tones are distinct and clear, the syndromes become evident.
Crying without tears indicates abdominal pain; weeping without crying suggests impending convulsions (Jing Feng). Restlessness due to decoction preparation leads to vexation and heat; hoarseness with a heavy voice indicates contraction of Wind-Cold (Feng Han). A robust and vigorous voice belongs to Excess syndromes (Yu You); a short and timid voice belongs to Deficiency syndromes (Bu Zu).
Excessive talking accompanied by body heat characterizes Yang Fu syndromes (Yang Fu Zheng); reluctance to speak accompanied by cold body characterizes Yin Zang syndromes (Yin Zang Zheng). Delirious speech with irritability indicates flourishing pathogenic Heat (Xie Re); coma with delirium indicates a critical heat syndrome (Bing Re Xiong).
A quacking sound stuck in the throat signifies the exhaustion of Qi (Qi Jiang Jue); a straight, urgent voice without resonance and tears signifies the dissipation of Qi (Qi Jiang San). Both are considered incurable syndromes.
By distinguishing between deficiency/excess and cold/heat through voice, one can perceive the condition upon hearing it, leaving no hidden aspects concealed.
[Note]
For pediatric diseases, besides observing the complexion, one must also carefully listen to the voice.
The five sounds—laughing, calling, singing, grieving, and groaning—correspond internally to the five Zang organs: Heart, Liver, Spleen, Lung, and Kidney.
Disharmony among the five sounds reveals the pathological state of the five Zang organs.
When the Heart, belonging to Fire, is diseased, the voice is rapid and prone to laughter.
When the Lung, belonging to Metal, is diseased, the voice is sorrowful and the tone turbid.
When the Liver, belonging to Wood, is diseased, the voice is wild with frequent calls.
When the Spleen, belonging to Earth, is diseased, the voice trembles lightly like singing.
When the Kidney, belonging to Water, is diseased, the voice is long and thin, resembling groaning.
Sound accompanied by tears and a long duration is called "crying" (Ku); sound without tears and a short duration is called "whimpering" (Ti).
If whimpering occurs without crying, it indicates stagnant and unsmooth Qi, primarily indicating abdominal pain.
If crying occurs without whimpering, it indicates urgent Qi and mental vexation, suggesting the formation of convulsions.
Restlessness associated with decoction preparation stems from internal Heat in the Heart meridian, causing dryness, irritability, and restlessness.
"Hoarse" (Sha) refers to a hoarse voice; "heavy" (Zhong) refers to a turbid voice; this indicates external contraction of Wind-Cold.
In Excess syndromes, Qi is solid, resulting in a robust, loud, and fierce voice.
In Deficiency syndromes, Qi is weak, resulting in a timid, weak, and short voice.
Excessive talking and body heat both belong to Yang; Yang governs the Fu organs, hence termed Yang Fu syndrome.
Reluctance to speak and cool body both belong to Yin; Yin governs the Zang organs, hence termed Yin Zang syndrome.
Delirious speech and irritability indicate flourishing pathogenic Heat.
Coma and delirium indicate Heat invading the Heart, thus termed critical heat syndrome.
A quacking sound in the throat that is hoarse indicates the imminent extinction of Qi.
A straight, urgent voice without resonance indicates the imminent dissipation of Qi. Both are incurable syndromes.
If physicians can observe using this method,
the states of exterior-interior, Zang-Fu, cold-heat, and deficiency-excess syndromes will be fully revealed without concealment.
