凡是小儿的声音，如果宏大而响亮，说明五脏六腑气血充盈，孩子必定容易健康成长。如果出生时不曾大声啼哭，这必然有一脏的阴窍未通，神气不足，或者声音像啾唧咿唔那样细微，这样的孩子必定寿命不长。所以望诊之后，又必须通过听声来辨别病情。诗云：要知道孩子的病是生是死，总观面色并审察声音。嘴唇青紫、耳朵发黑的孩子难以救治，哭声不响亮的将去见阎王（赴阴君）。
五音对应五脏。金主声响，土主声浊，木主声长，水主声清，火主声燥。
心发出的声音从肺排出。肺气绝则啼哭无声。多啼叫是因为肝胆受客风惊扰。气缓神疲且抽搐盛者，音哑是邪热侮肺所致。声音清亮说明毒火无侵。疼痛之声直来且泪不流。鸦叫声预示黄泉有分（死亡）。声音轻弱者孩子气必弱。声音重浊多是痛证与风邪。狂声高喊说明热邪在中焦。声音颤抖说明寒气已重。声音急促连连不绝，多泪必定是神志受惊。声音带闷塞感说明痰在心胸。喘气噎阻说明气机不顺行。肝病声音悲切，肺气促迫。脾病声音缓慢，心病声音雄壮。小肠病声音短促大不相同。大肠病声音较长较纵。肾病声音深沉，胃病声音快速。胆病声音清亮，膀胱病声音微弱。声音重浊沉静多为疳积亏损。聆听声音可知病的源委。伤风必定多喷嚏。呵欠倦怠是神气受伤。撮口、鸦声、气急上扬。蹼跌（扑倒）受喝惊张。
三周以下的孩子有病，男看左手女看右手的三关。寅位是风关，卯位是气关，辰位是命关，到了命关医生难治。虎口处的筋脉往上延伸，观察时必须分辨五色。红黄色表示安乐，五脏调和。青色紫色定为其受惊吓。筋纹入掌生枝恐怕不吉祥。（若筋冲过三关，又分出个枝，其症十死一生，惟独久咳不在此例。）筋透三关命必亡。初关乍入推宜早治。次节相侵亦可防。
筋赤定然因膈食。筋青端的是水风伤。筋连大指是阴症候。（阴者，寒深入也，花生寅卯位，主虫，又主脏败，凶。）筋若生花主不祥。
筋带悬针主吐泻。筋纹向外命难当。四肢瘫软腹膨胀。吐乳却因乳食伤。丫鱼刺、伤风向外者。冲过命关。向大肠倒去。
In general, if a child's voice is loud and resonant, it indicates that the five zang organs and six fu organs are full of qi and blood, and the child will likely grow up healthy. If the infant does not cry loudly at birth, it implies that the yin orifices of one organ are not yet open, and the spirit (shen) and qi are insufficient. The voice may be like chirping or mumbling; such children are likely to have short lifespans. Therefore, after inspection (wang), listening (wen) is also necessary to differentiate the condition. As the poem states: "To know whether a child's illness leads to life or death, observe the complexion and examine the voice." Cyan lips and black ears indicate a difficult-to-save case; a weak cry suggests approaching death.
The five tones correspond to the five zang organs. Metal governs sound resonance, Earth governs turbid sound, Wood governs long sound, Water governs clear sound, and Fire governs dry/rough sound.
The sound produced by the Heart emerges from the Lung. When Lung qi is exhausted, crying is silent. Frequent crying is due to guest wind disturbing the Liver and Gallbladder causing fright. Sluggish qi, weary spirit, and intense convulsions indicate that hoarseness is caused by pathogenic heat insulting the Lung. A clear voice indicates no invasion by toxic fire. Painful sounds come directly without tears. An "crow-like" voice indicates impending death (yellow springs). A light voice indicates weak qi in the child. A heavy and turbid voice indicates pain and wind. Manic shouting indicates heat in the middle jiao. Trembling voice indicates severe cold qi. Rapid, continuous sounds with excessive tearing indicate spirit fright. A muffled voice indicates phlegm in the heart/chest. Wheezing and choking indicate obstructed qi movement. Liver disease presents with sad sounds and rapid breathing; Spleen disease with slow sounds; Heart disease with vigorous sounds. Small Intestine disease presents with short sounds; Large Intestine disease with long sounds. Kidney disease presents with deep sounds; Stomach disease with rapid sounds. Gallbladder disease presents with clear sounds; Bladder disease with faint sounds. Heavy, turbid, and quiet sounds indicate deficiency from malnutrition (gan accumulation). Listening to the voice reveals the origin of the disease. Wind-cold injury involves frequent sneezing. Yawning and fatigue indicate spirit injury. Mouth puckering, crow-like voice, and rapid rising breath indicate urgency. Falling and being startled cause tension.
For infants under three weeks old with illness, observe the Three Passes on the left hand for boys and the right hand for girls. Yin position is the Wind Pass, Mao position is the Qi Pass, and Chen position is the Life Pass; reaching the Life Pass makes treatment difficult by physicians. Veins extending upward from the tiger's mouth must be observed and differentiated into five colors. Red and yellow indicate peace and harmony of the five zang organs. Cyan and purple indicate fright. Veins entering the palm and branching suggest misfortune. (If veins rush through the Three Passes and branch out, the prognosis is ten deaths to one survival, except for chronic cough.) Veins penetrating through the Three Passes indicate certain death. Early entry into the first pass requires early intervention. Invasion of the second section can still be prevented.
Red veins definitely indicate food stagnation in the diaphragm. Cyan veins indicate water-wind injury. Veins connecting to the thumb indicate yin syndrome patterns. (Yin refers to deep cold invasion; flowers appearing at Yin/Mao positions indicate parasites or organ failure, which is ominous.) Flowers appearing on veins indicate misfortune.
Veins resembling a hanging needle indicate vomiting and diarrhea. Veins extending outward make survival difficult. Flaccid limbs and abdominal distension. Vomiting milk due to improper feeding. Forked fish spine pattern, wind-cold extending outward. Rushing past the Life Pass. Reversing towards the Large Intestine.
