Abstract：
OBJECTIVE: We aimed to evaluate the effect of voice training in patients with head and neck cancer who were undergoing radiotherapy.
METHODS: This study used a randomized controlled trial design. IBM SPSS 26.0 was used to randomly divide 74 patients into a control group and an experimental group. The control group followed a swallowing exercises program, and the experimental group additionally received ABCLOVE voice training. Both training programs continued throughout the entire radiotherapy cycle. We compared standardized swallowing assessment (SSA), maximum phonation time (MPT), the Voice Handicap Index-10, and incidence of complications such as difficulty opening the mouth, malnutrition, and aspiration between the two groups at T1 (0 radiotherapy sessions, before radiotherapy), T2 (15-16 radiotherapy sessions, middle of radiotherapy), and T3 (30-32 radiotherapy sessions, end of radiotherapy).
RESULTS: 70 participants completed this study. Swallowing function and MPT intergroup and interaction effects were statistically significant between the two groups (P < 0.05). At the end of radiotherapy (T3), the SSA score (20.77 ± 1.96) and MPT (10.98 ± 1.75) s in the experimental group were superior to those in the control group (SSA: 22.06 ± 2.38 and MPT: 9.49±1.41 s), with statistical significance (P<0.05). Moreover, the incidence of malnutrition and aspiration in the experimental group was lower than that in the control group (P < 0.05).
CONCLUSIONS: Voice training can improve swallowing function and MPT and reduce complications related to swallowing disorders in patients with head and neck cancer.

摘要：
目的：我们旨在评估声音训练在接受放疗的头颈部肿瘤患者中的效果。
方法：本研究采用随机对照试验设计。采用IBMSPSS26.0将74例患者随机分为对照组和实验组。对照组遵循吞咽锻炼计划，实验组额外接受ABCLOVE语音训练。两种训练方案在整个放射治疗周期中持续进行。我们比较了标准化吞咽评估(SSA)，最大发声时间（MPT），语音障碍指数-10，以及张口困难等并发症的发生率，营养不良,和两组在T1时的误吸（0次放疗，放疗前)，T2（15-16次放射治疗，放射治疗的中间)，和T3（30-32次放射治疗，放射治疗结束)。
结果：70名参与者完成了这项研究。两组患者吞咽功能、MPT组间及交互作用差异均有统计学意义(P<0.05)。放疗结束时（T3），实验组的SSA评分（20.77±1.96）和MPT（10.98±1.75）s优于对照组（SSA：22.06±2.38和MPT：9.49±1.41s），具有统计学意义(P<0.05)。此外，实验组营养不良和误吸发生率低于对照组(P<0.05)。
结论：语音训练可以改善头颈部肿瘤患者的吞咽功能和MPT，减少与吞咽障碍相关的并发症。
