This paper deals with a new noninvasive method of estimating vocal cord polyp features through hoarse-voice analysis. A noteworthy feature of this method is that it enables us not only to discriminate hoarse voices caused by pathological vocal cords with a single golf-ball-like polyp from normal voices, but also to estimate polyp features such as the mass and dimension of polyp through the use of a novel model of pathological vocal cords which has been devised to simulate the subtle movement of the vocal cords. A synthetic hoarse voice produced with a hoarse-voice synthesizer is compared with a natural hoarse voice caused by the vocal cord polyp in terms of a distance measure and the polyp features are estimated by minimizing the distance measure. Some estimates of polyp dimension that have been obtained by applying this procedure to hoarse voices are found to compare favorably with actual polyp dimensions, demonstrating that the procedure is effective for estimating the features of golf-ball-like vocal cord polyps.
本文探讨了一种通过嗓音分析估计声带息肉特征的新型非侵入性方法。该方法的一个显著特点是，它不仅能将由单个高尔夫球样息肉引起的病理性声带导致的嗓音与正常嗓音区分开来，还能通过使用一种新设计的病理性声带模型来估计息肉特征，如息肉的大小和尺寸，该模型旨在模拟声带的细微运动。利用距离度量将由嗓音合成器生成的合成嗓音与声带息肉引起的自然嗓音进行比较，并通过最小化距离度量来估计息肉特征。通过将该程序应用于嗓音而获得的一些息肉尺寸估计值与实际息肉尺寸相比具有优势，这表明该程序对于估计高尔夫球样声带息肉的特征是有效的。
