The speech of nine laryngectomized persons is analysed. Both tracheo-esophageal and esophageal speakers are included. The speech performance of the subjects is evaluated while they are reading texts aloud with varying amounts of noise in their ears. One hypothesis is that the amount of noise will influence the articulation skill and voice behaviour of the speakers. Preliminary results show that some of the tracheo-esophageal speakers were able to raise their voice level as much as the normal laryngeal speakers. The esophageal speakers on the other hand were usually not able to produce as strong voice levels during the text readings. Acoustic speech parameters, such as sound pressure and spectral characteristics were measured and compared among the subjects. when the speakers were forced to use a great deal of effort, they spent air rapidly and had to use shorter stretches of speech with many pauses for inhalation.
