Takeaway 🏃

Zusammenfassung:: This paper studies the difference between male and female voices, with respect to both the perceived quality, as judged by crowdsourced raters, as well as to findings from previous prosodic analyses. In regard to Elizabeth Holmes’ voice compares with their findings.

Motivation:: “first gender-balanced study of charismatic speech”


  • 01 | Generating voices with phonological characteristics which supposedly are “charismatic” actually led to increased perception of charisma in listeners
  • 02 | Lit review references: @rosenberg2009, Biadsy et al., @signorello2012, @niebuhr2016a
  • 02 | Gender bias: Female speakers typically give stronger charisma cues yet are perceived equally strong → Could be skewed because previous data from only-male studies
  • 03 | Explanation of their methods, they crowdsourced ratings with MTurk and accounted for quality by introducing some “trick questions”
    • ? What are Human Intelligence Tasks?
  • 03 | They asked raters to record their own voice, once in natural and again in a “charismatic” tone
  • 04 | Normalized speech to get overall influence of prosodic features, then measured split by gender → louder, higher, faster, dynamic speech
  • 04 | Mean intensity only relevant with female voices, pitch and speaking rated correlated in male voices
