The aim of this study was to develop and validate the first ever speech-specific perceptual speech-evaluation tool for patients with head and neck cancer.
Five speech parameters (intelligibility, articulation, speech rate, nasality, and asthenia) and overall grade were included and evaluated. Speech samples of 117 subjects were recorded on electroglottograph equipment using a standard protocol and were independently judged and rated by 3 experienced speech and language therapists and re-rated 12 weeks apart.
Among patients the Cronbach's alpha (α) coefficients for internal consistency for connected speech were 0.89, whereas for single words the α coefficients ranged between 0.80 and 0.84. The Spearman's correlation coefficients for intra-rater reliability for connected speech and words varied between 0.30 and 0.90 and 0.49 and 0.76, respectively, whereas for inter-rater reliability the coefficients ranged between 0.53 and 0.99 and 0.56 and 0.99, respectively. For construct validity, the Spearman's correlation coefficient ranged between 0.41 and 0.55.
The London Speech Evaluation (LSE) scale demonstrated a high reliability and validity in our cohort of patients with head and neck cancer. surgery.
本研究旨在开发并验证首个针对头颈部癌症患者的特定于言语的感知言语评估工具。
纳入了 5 个言语参数（可懂度、清晰度、言语速度、鼻音度和乏力度）和整体等级，并进行了评估。117 名受试者的言语样本使用标准方案通过言语电声门图设备进行记录，由 3 名经验丰富的言语和语言治疗师进行独立判断和评分，并在 12 周后重新评分。
在患者中，连贯言语的内部一致性 Cronbach's alpha（α）系数为 0.89，而单词语音的 α系数范围在 0.80 至 0.84 之间。连贯言语和单词的内部评估者可靠性的 Spearman 相关系数分别在 0.30 至 0.90 和 0.49 至 0.76 之间，而外部评估者可靠性的系数范围分别在 0.53 至 0.99 和 0.56 至 0.99 之间。对于结构有效性，Spearman 相关系数范围在 0.41 至 0.55 之间。
伦敦言语评估（LSE）量表在我们的头颈部癌症患者队列中表现出了较高的可靠性和有效性。
