**What else can we learn from this?** The auditory feedback we gain from choral speech contains not just the sound of our own voice, but also other people’s voices, so when speaking chorally, we are not normally able to hear our own voice in isolation. Hence we are far less likely to negatively evaluate it. Furthermore, in choral speech we tend to focus primarily on speaking in time with the others, so our focus is on the timing and the forward flow, rather than on the quality of our articulation – so there is a distraction effect too. The reason speaking in unusual or false voices tends to only produce temporary fluency is almost certainly because any novel action leads to a transient increase in phasic dopamine release in the brain. This increase in phasic dopamine lowers the threshold for the release of motor plans for motor execution, and essentially makes it easier to get words out (and indeed easier to perform any related action). This phenomenon is explained in detail in the papers on dopamine. Essentially, novelty increases “approach” behaviour and decreases “avoidance” behaviour. We are biologically programmed that way.
