Stimulation protocols were established during baseline examination and confirmed with endoscopy to ensure a glottal reaction. Numerous acoustical, vocal, patient\u2010centered, and respiratory parameters were obtained at several time points.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Neither 4\u2009weeks nor 8\u2009weeks of functional electrical transcutaneous stimulation led to changes of vocal, acoustical, or respiratory parameters, apart from patient\u2010centered items (Voice Handicap Index 12, Voice\u2010Related Quality of Life), which improved over time. However, there were no differences between the two arms for both items.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Transcutaneous FES over 4\u2009weeks and 8\u2009weeks did not lead to significantly improved objective voice and acoustical parameters, which could be caused by the fact that the muscles of interest cannot be targeted specifically enough. However, we found a significant improvement of subjective voice perception and voice\u2010related quality of life in both groups. We explain this finding with an observer\u2010expectancy effect secondary to the very time\u2010consuming and elaborate study procedures.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of
