This paper is a progress report, discussing methods and preliminary results of acoustic analysis of laryngectomee speech. We have investigated three types of alaryngeal voices: esophageal speech, tracheo-esophageal speech and electrolaryngeal speech and made comparisons with normal laryngeal speech. Our aim is to obtain an acoustic objective evaluation of the different speaking methods and to relate perceptual dimensions to acoustic measurements. Prosodic features, such as pitch, intensity, duration, as well as voice quality features, including long time average spectral shape and aspects of spectral energy distributions were measured. Among the results it was found that the alaryngeal voices were characterized by weak level of the fundamental compared to normal laryngeal voices. Other, more detailed voice source characteristics, such as inverse filtered flow registrations were analysed and revealed strong irregularities for the alaryngeal voices.
