From the perspective of efficiency, this article studied the energy transfer and conversion in the process of electrolaryngeal (EL) speech production. An overall vocal efficiency of EL speech production was defined as the ratio of the acoustic power of the EL speech to the electric power supplied by the battery. The measurements of a commercial EL showed that the actual utilization efficiency of the...
Lack of an appropriate voice source is the main reason for low intelligibility of the electrolaryngeal (EL) voiceless consonants. It is essential that the influence of neck tissue on EL voiceless consonant production is studied in order to design a suitable voice source. Firstly, the neck frequency response function was measured across a wide frequency range (100–20,000Hz) to investigate the potential...
