Re: [AUDITORY] Effect of sidetone in lowering one's own voice



Thanks Ole. (Also to Dhurandar and JJ who responded outside of the list).

I am interested in the Fletcher Effect and the Lombard effect. Both of those show variations in the speaker’s own voice (level, format shifts, etc) in the presence of noise or sidetone (i.e. own voice fed back into the ear usually through headphones).

Is there evidence to suggest that the Fletcher and the Lombard effect are essentially the same effect - where the perceived SNR of the ‘own voice’ is causing a level rise in the ‘own voice’? 

Also, while there is evidence to suggest that ‘own voice’ is raised in the presence of noise or ‘lower feedback of the own voice through sidetone’, is there evidence of lowering the voice to below nominal/ambient levels when the sidetone is raised substantially (where in the extreme case, the speaker would be whispering when the sidetone is played back at a high enough level).

Thanks,
Deep

Hi Deep,

That depends on whether you are asking about a relative/absolute decrease of pitch or amplitude?

Might be of interest, if it's pitch:

Are folks aware of work that studies he lowering of one’s own voice when there is feedback of their voice through side-tone (through headphones)?


Thanks,
