The association between EEG-derived sleep measures and the change of emotional status analyzed from voice: observational pilot study
ABSTRACT
Background:
Measuring emotional status objectively is challenging, but voice pattern analysis has been recently reported to be useful in the study of emotion.
Objective:
The purpose of this article is to investigate the association between specific sleep measures and the change of emotional status based on voice patterns measured before and after night-time sleep.
Methods:
We recruited 20 volunteers and obtained objective sleep measures using a portable single-channel EEG system and asssessed their emotional status using MIMOSYS, a smartphone application analyzing voice patterns. We analyzed 73 sleep episodes for the association between the change of emotional status following night-time sleep (delta vitality) and specific sleep measures.
Results:
We identified a significant association between total sleep time and delta vitality (regression coefficient: 0.036, p=0.008). We also found a significant inverse association between sleep onset latency and delta vitality (coefficient: -0.026, p=0.001). We did not detect any significant association between delta vitality and sleep efficiency or number of awakenings.
Conclusions:
Total sleep time and sleep onset latency are significantly associated with delta vitality, a change of emotional status following night-time sleep. This is the first study to report the association between emotional status assessed using voice pattern and its association with specific sleep measures.
