It was proprioceptively felt that voiced and aspirated voiced stops in Sindhi are characterized by a slight nasalization. Nasal airflow during the production of voiced stops was therefore measured with a Froikaer-Jensen Electro-Aerometer. Results suggest that there is an imcomplete velopharyngeal closure which helps to absorb the transglottal airflow and thus prevents the rise in the supraglottal pressure. For the affricated palatal stops of Sindhi, the vocal fold vibrations were, however, maintained by expanding the walls of the supraglottal cavities.
人们凭本体感觉认为，信德语中的浊音和送气浊塞音具有轻微的鼻音特征。因此，使用弗罗凯尔 - 詹森电动气流计测量了浊塞音发音过程中的鼻气流。结果表明，存在不完全的腭咽闭合，这有助于吸收经声门的气流，从而防止声门上压力升高。然而，对于信德语中的腭塞擦音，声门以上腔室壁的扩张维持了声带振动。
