Query: Towards the Objective Speech Assessment of Smoking Status based on Voice
  Features: A Review of the Literature   In smoking cessation clinical research and practice, objective validation of
self-reported smoking status is crucial for ensuring the reliability of the
primary outcome, that is, smoking abstinence. Speech signals convey important
information about a speaker, such as age, gender, body size, emotional state,
and health state. We investigated (1) if smoking could measurably alter voice
features, (2) if smoking cessation could lead to changes in voice, and
therefore (3) if the voice-based smoking status assessment has the potential to
be used as an objective smoking cessation validation method.
