+* My works in vocal synthesis
+From 2011 to 2018, I worked as an amateur and professional in singing
+vocal synthesis. More precisely, I was creating vocal libraries used
+by various libraries, mainly UTAU and Alter/Ego.
+
+** UTAU
+I began working with UTAU first by the end of 2011 on an unnamed and
+deleted Japanese vocal library. While I didn’t maintain it for long,
+mainly due to its bad recording quality (I recorded it with a low-end
+desktop microphone) and configuration, it did teach me the basics of
+creating vocal libraries and working with audio files.
+
+In October 14th, 2012, I released my second vocal library, named
+/BSUP01 KEINE Tashi JPN VCV/ which was of higher quality both due to the
+recording equipment, manner of recording, and configuration, though
+still relatively average for the time. My best work with this series
+of vocal libraries was /BSUP01 KEINE Tashi JPN Extend Power/, a
+high-energy voice made in similar circumstances but with yet again
+better know-how.
+
+This series of vocal libraries also featured /BSUP01 KEINE Tashi TIB
+CVVC/ and /BSUP02 Drolma TIB/, the two first Tibetan vocal libraries for
+singing vocal synthesis worldwide.
+
+I later created in UTAU /ALYS 001 JPN/, /ALYS 001 FRA/, and /ALYS 002 FRA/
+as prototypes, known as /ALYS4UTAU/, for our upcoming product while
+working at VoxWave.
+
+While all these vocal libraries have been discontinued, vocal
+libraries for /BSUP01 KEINE Tashi/ and /ALYS/ are available for download.
+Please refer to the following pages:

+
+** Alter/Ego
+[[https://www.plogue.com/products/alter-ego.html][Alter/Ego]] is a singing vocal synthesis engine made by [[https://www.plogue.com/][Plogue Inc.]].
+ALYS was its first commercial vocal library as well as the first
+professional singing vocal library available in French.
+
+Due to the architecture and behaviour of Alter/Ego, important changes
+had to be done to the recording script for ALYS (later re-used for
+LEORA). Including the development of the new recording scripts, the
+initial development period for ALYS spanned well over a year, with
+some additional eight to nine months for its first major update.
+
+ALYS for Alter/Ego, also known as /ALYS4AE/, is available free of charge
+as a module for Alter/Ego, and its source files are publicly available
+since December 15th, 2021. However, in accordance with Plogue, no
+reciepe for building ALYS for Alter/Ego have been made available.
