Supracricoid partial laryngectomy is the widest conservation technique for glottic carcinoma. Voice is produced without consonants and V = /a/) produced by 10 patients, vocal folds. 6 French listeners (3 naive and 3 experts) identified 2880 monosyllables [C-V] (where C represents the 16 French 18 months after surgery. Expert and naive listeners misidentified 23 % and 24 % of voiced consonants as voiceless, respectively . There was less than 2 % of manner confusions and there were 16 % and 28 % errors in place of articulation, mainly for palato-velar consonants, respectively. The sonorants /l, m, n, r/ were well identified. The jury's experience was somewhat determinant for consonant identification.
