We built voice modulation to mask gender in technical interviews
I would really have liked to see them check whether the gender-blinding actually worked. Even if someone's voice is modulated, they may have gendered behavior patterns that could influence someone's performance ratings. I wouldn't be surprised if I could guess the gender of a voice-modulated person pretty accurately from other cues.To combat this, they could have asked the interviewer during the performance assessment whether they thought the applicant was definitely male/probably male/unsure/probably female/definitely female. Then you could use voice modulation as an instrument for perceived gender and get a better estimate of the true effect of perceived gender when controlling for actual gender.Hope they do something like that for the next round of experiments!
