The first portion of the audio (comprising all I heard) is just some guy kvetching about Alexa to a clueless but still pompous interviewer. As for "biometrics", per sei, it seems to be a marginally small addition to all the other information channels that are available to the surveillance industry. Not momentous in and of itself, and the concern seems to stem from questionable categorical distinctions (e.g. what you say vs. how you say it; wrong for others to consider the latter, not the former). And, regarding phrenology: its previous incarnation was discredited as a pseudoscience on the basis of its vagueness and potential inaccuracy. Now that it can be implemented using deep learning, its predictions' accuracy quantified and vetted empirically, that criticism no longer applies.
