Randomized controlled trial of text-to-speech communication versus standard of care in patients on prescribed voice rest
Subjects will be randomized to an experimental group or a control group. The experimental group will receive the standard-of-care treatment of voice rest for 7 days plus a TTS device, while the control group will receive only the standard-of-care treatment of voice rest for 7 days.
The study will involve: 1) a 15-20 minute training session to orient subjects to the TTS device (if randomized to receive), and 2) completion of study-related questionnaires both prior to and during their prescribed voice rest. The study-related instruments will evaluate the amount of pre- and post-surgical voice use, utilization of the device and/or other means of non-speech communication, and the impact of voice rest on study participant?s day-to-day lives.
The outcome variables are:
1) Communication effectiveness during the period of voice rest, as self-reported on a 100-mm visual analogue scale (VAS), anchored by 0 (not at all) and 10 (every time I wanted to communicate), in response to the question ?I was able to communicative effectively today without using my voice or whispering?.
2) Cumulative magnitude of voice use over the seven-day period of voice rest, as measured on a 100-mm VAS, anchored by 0 (not at all) and 10 (every time I wanted to communicate), in response to the question ?How much did you use your voice today (including whispering)? I used my voice ??.
3) Score on neuroticism and extraversion scales of NEO-Five Factor Inventory.
