This case study investigated the changes in speech intelligibility of patients with head and neck cancers who participated in a therapeutic singing-based intervention. Three patients received a total of twelve 30-minute individual sessions. The intervention consisted of three steps: movements for relaxing breathing muscles, vocalization for increasing the range of articulatory movements, and therapeutic singing. In order to examine the changes in speech intelligibility, the voice quality parameters, diadochokinesis (DDK) and the quadrangle vowel space area (VSA) were measured at pre- and posttest. The recording of what each patient read a written paragraph, which were transcribed by blinded assessors, were also analyzed. The results demonstrated that all of the patients showed positive changes in the voice quality, the rate of repetitive syllable production measured by DDK, and the articulatory working space measured by VSA. Along with these measured changes, increases in positive mood and rehabilitation motivation reported by the patients support that the therapeutic singing-based intervention could induce meaningful changes in terms of speech intelligibility from patients with head and neck cancers. Given that this study was conducted with a small sample size, suggestions for further investigation on the effects of the intervention were also presented.

배경 : 주로 palatal defect 환자들의 상악(maxilla)의 결손으로 인한 형태와 기능을 복구시키기 위한 보철적 재활(prosthetic rehabilitation)방법으로 쓰이는 obturator는 비음의 초래를 막고 vocal tract의 모양에 영향을 줄 수 있으나, palatal cancer 환자를 대상으로 말산출(speech production)에 관한 obturator 장착 효과에 대한보고는 거의 없다. 또한 모음은 자음에 비해 더 nasality에 영향을 주며 모음 삼각도의 면적크기가 말 명료도의 객관적인 측정치로 사용될 수 있다. 연구목적 : Palatal cancer 환자의 obturator 장착 전후 모음 산출 측정치를 통해 모음 삼각도의 크기를 비교함으로써, obturator 장착이 말 명료도 개선에 어느 정도의 효과를 주는지 보고자 하였다.

The study aimed to develop Speech Range Profile (SRP) and to examine and validate its clinical application. Forty-five participants without voice disorders aged 18-29 years were compared using SRP and Voice Range Profile (VRP). The authors developed the "Fire!" paragraph as a SRP task compromising 14 sentences including all Korean spoken phonemes and sentence types. To compare SRP and VRP results, the participants read the paragraph (reading) and counted from 21 to 30 (counting) as a part of SRP tasks, and produced a vowel /a/ from low to high frequencies (gliding) and a shortened form of the VRP as a part of VRP tasks. $F0_{max}$, $F0_{min}$, $F0_{range}$, $I_{max}$, $I_{min}$, and $I_{range}$ for each task were measured and compared, showing that $F0_{max}$, $F0_{min}$, $F0_{range}$, $I_{max}$, and $I_{range}$ were not different between reading and gliding. $I_{min}$, had the lowest value in counting. It is concluded that the newly developed SRP task, reading the "Fire" paragraph, can yield a maximum phonation range similar to that found by VRP. Therefore, it is expected that voice evaluation can be effectively performed in a relatively short time by applying SRP with the "Fire" paragraph, a functional utterance task, in place of VRP, which may be difficult to measure long term or in cases of severe voice disorders.
