Acoustic analysis of tracheo-oesophageal voice in male total laryngectomy patients

Abstract

Alaryngeal speech with TO voice prosthesis is not yet comparable to laryngeal speech.

Objective and subjective voice outcomes after total laryngectomy: a systematic review

“…Groups of interest were ES ( n = 313), TES ( n = 482), ELS ( n = 135), and a control group of healthy, i.e., laryngeal speakers ( n = 167). Six studies only included male participants [ 29 – 31 , 44 , 45 , 48 ]. One study only included female participants [ 32 ].…”

“…Ten studies [ 27 , 29 , 33 – 35 , 37 , 38 , 44 , 47 , 54 ] did not mention any inclusion criteria. Eleven studies [ 27 , 29 , 32 – 35 , 43 , 47 , 48 , 51 , 54 ] failed to describe their method of selection and recruitment of participants. Two studies [ 30 , 36 ] provided a detailed description of the selection process.…”

“…Treatment details of the included groups were only provided in about half of the studies [ 27 – 29 , 31 , 32 , 36 – 38 , 41 , 42 , 45 , 49 ]. This variable was indicated as present when treatment details were provided.…”

“…131 Hz and 124 Hz. Higher mean F 0 values are found for healthy speakers compared to ES and TES ( N = 7) [ 27 , 29 , 30 , 32 , 33 , 35 , 37 ]. In two studies this difference was significant [ 27 , 33 ].…”

“…Eight studies [ 27 – 29 , 31 , 32 , 34 , 38 , 47 ] (n = 240) included Harmonics to Noise Ratio (HNR) outcomes, including one level A study of Shim et al [ 28 ], and seven level B studies [ 27 , 29 , 31 , 32 , 34 , 38 , 47 ]. Two studies measured Noise to Harmonics Ratio, which was recalculated to HNR [ 28 , 34 ].…”
