Comparison of alaryngeal voice and speech.
The aim of the research was to compare voice and speech in three groups of alaryngeal speakers: 1) patients using esophageal speech, 2) patients with electro-acoustical speech aids and 3) patients with voice prostheses. Acoustic analysis and pronunciation tests were used for the analysis. Acoustic analysis included fundamental frequency, maximum phonation time, jitter, shimmer and intensity. Pronunciation parameters were: phonetic block duration, number of syllables in a phonetic block, rate of speech, maximum number of syllables in a phonetic block and rate of articulation in a maximal phonetic block. Our results demonstrated the advantages of tracheoesophageal puncture with implantation of a voice prosthesis over the other two techniques of alaryngeal speech. Voice and pronunciation with voice prostheses were closer to normal in many parameters: fundamental frequency, maximum phonation time, jitter, shimmer, duration of a phonetic block, number of syllables in a phonetic block, rate of speech and rate of articulation in maximal phonetic block.
