Abstract:
Objective: The current work aims to design and develop an automatically controlled wearable
electrolarynx, a voice substitution device for laryngeal carcinoma survivals. Methods: The physical
activity of mouth opening is sensed, amplified, and made to act as an enable signal to trigger
the wearable electrolarynx. The resulting speech is recorded and compared for its voice reaction
durations with that of manual electrolarynx and normal speaking methods. Perception evaluations
of ۵ subjects from ۱۰ speech‑language therapists are obtained. Results: The wearable electrolarynx
turn‑on in ۱۳ μs once the mouth movement for speech is sensed. The voice initiation time and
termination durations are ۲۱۵.۶۸ m and ۲۳۱.۴۱ ms, respectively. Results indicate that there is no
significant difference (P < ۰.۰۵) between the voice reaction durations of wearable electrolarynx
and normal speaking methods. The subjective evaluation results show that there is a significant
improvement (P < ۰.۰۵) in intelligibility and noise reduction when compared to a commercially
available electrolarynx with an average intra‑class correlation coefficient of ۰.۶۸ from analysis
of variance two factors without replication. Conclusions: The assessment of the wearable and
automatically controlled electrolarynx provides hands‑free speech and easy control over the device.
