An interactive tool to investigate relations between vocal tract transfer function,
pole frequencies and bandwidths, shape, LSF (LSP), and synthesized sounds is added to
Matlab realtime speech tools. Stand alone applications for Mac and Windows,
which do not require Matlab installation are also available (15/May/2015)
A completely new reformulation of STRAIGHT (TANDEM-STRAIGHT) was presented at ICASSP2008.

Auditory morphing demonstrations on emotional speech. (Flash movie)
This demonstration was on display at National Museum of Emerging Science and Innovation Tokyo
from 23 April to 15 August 2006. The title of the special event was
"Love stories - Why you are not alone.".
The interface was designed by Takashi Yamaguchi and
auditory morphing sounds were synthesized by Hideki Kawahara using
STRAIGHT-based morphing algorithm.
STRAIGHT based TTS (Text To Speech) system won the first place in the Blizzard challange and reported at
INTERSPEECH2005. (Sept. 2005).
"Temporal media design project" supported by CREST (Aka CrestMuse project)
(2005 to 2010: PI is Prof. Katayose and I will take part) uses STRAIGHT as one of key components. (Sept. 2005).
Invited talk on "Manipulating the pulse rate and resonance scale in speech and animal calls",
at the special session "Size information in speech and animal calls" (organized by
at the 149th ASA meeting in Vancouver, Canada. (May 2005).
