J Speech Lang Hear Res. 2014 Jun 1;57(3):734-42. doi: 10.1044/1092-4388(2013/13-0096).
PURPOSE
The purpose of this study was to determine the typical pattern for inspiration during speech breathing in healthy adults, as well as the factors that might influence it.
METHOD
Ten healthy adults, 18–45 years of age, performed a variety of speaking tasks while nasal ram pressure, audio, and video recordings were obtained. Inspirations were categorized as nasal-only, oral-only, simultaneous nasal and oral, or alternating nasal and oral inspiration. The method was validated using nasal airflow, oral airflow, audio, and video recordings for 2 participants.
RESULTS
The predominant pattern was simultaneous nasal and oral inspirations for all speaking tasks. This pattern was not affected either by the nature of the speaking task or by the phonetic context surrounding the inspiration. The validation procedure confirmed that nearly all inspirations during counting and paragraph reading were simultaneous nasal and oral inspirations, whereas for sentence reading, the predominant pattern was alternating nasal and oral inspirations across the 3 phonetic contexts.
CONCLUSIONS
Healthy adults inspire through both the nose and mouth during natural speech breathing. This pattern of inspiration is likely beneficial in reducing pathway resistance while preserving some of the benefits of nasal breathing.
目的
本研究旨在确定健康成年人在言语呼吸时的典型吸气模式，以及可能影响吸气模式的因素。
方法
10 名 18-45 岁的健康成年人在进行各种言语任务时，同时记录鼻压、音频和视频。吸气被分为单纯鼻式、单纯口式、同时鼻式和口式以及交替鼻式和口式吸气。该方法通过对 2 名参与者的鼻气流、口气流、音频和视频记录进行验证。
结果
所有言语任务中，最主要的吸气模式是同时鼻式和口式吸气。这种模式不受言语任务的性质或吸气周围的语音环境的影响。验证程序证实，在数数和段落阅读过程中，几乎所有的吸气都是同时的鼻式和口式吸气，而在读句子时，在 3 种语音环境下，主要的吸气模式是交替的鼻式和口式吸气。
结论
健康成年人在自然言语呼吸时通过鼻子和口腔同时吸气。这种吸气模式可能有助于降低气道阻力，同时保留一些鼻呼吸的益处。
