Subject: Re: [AUDITORY] Effect of sidetone in lowering one's own voice From: D Sen <dsen@xxxxxxxx> Date: Fri, 28 Jun 2019 13:30:19 -0700 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--Apple-Mail=_11A83295-91DD-4D9D-95B7-95E38BA5B88A Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=utf-8 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=E2=80=99s 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 =E2=80=98= own voice=E2=80=99 is causing a level rise in the =E2=80=98own voice=E2=80= =99?=20 Also, while there is evidence to suggest that =E2=80=98own voice=E2=80=99 = is raised in the presence of noise or =E2=80=98lower feedback of the own = voice through sidetone=E2=80=99, 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).
