Subject: Re: [AUDITORY] Effect of sidetone in lowering one's own voice From: Dhurandar Singh <ttftufj@xxxxxxxx> Date: Mon, 1 Jul 2019 08:02:35 +0200 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--0000000000007c2661058c9860e4 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Hi Deep, The paper mentioned in my previous email, Lane, H. & Tranel, B. The Lombard sign and the role of hearing in speech. *Journal of Speech, Language and Hearing Research* *14*, 677 (1971), summarizes the Fletcher effect, Lombard's papers and other early research (circa 1970) in the area. It is a fairly long paper, but quite comprehensive. Cheers, Manuj On Sat, Jun 29, 2019 at 6:31 AM D Sen <dsen@xxxxxxxx> wrote: > Thanks Ole.
