Performance Modeling technology can Enhance Yamaha Vocaloid!

9th Example: LEON knows Russian!
August, 07, 2004.


New example is an attempt to force Vocaloid to sing in Russian using English phonemes.
For this experiment we used a very famous Russian (Soviet period) song "Yest Tolko Mig" ("There Is Only A Moment") and a simple PM Style.

For tune PMStyle have calculated:

  • Velocity changes
  • Auto phrasing
  • Harmonics curve
  • Pitch Bend gliding
  • Parameters of "Vibrato Objects"
  • Noise curve

No manual editing at all!

To analyze the result yourself you can take the following files in mp3 and *.mid format:

Yest_Tolko_Mig_(Full)_(voice_and_background).mp3 [2,87MB]
Yest_Tolko_Mig_(Short)_(voice_and_background).mp3 [1,67MB]


Verse #1 and Refrains #1-1 and #1-2 Vocaloid MIDI files in ZIP.

Comments by Alexei Ustinov, CTO Jasmine Music Technology

It's been a week now that most of our team has returned from summer vacation to take care of the job that remained unfinished since late August. A number of more important projects keep us from concentrating our attention completely on YV Enhancer, but this job will definitely be finished.

9th Example: To our team members, myself included, the pronunciation seems quite comprehensible, maybe even more so than LEON's English. Naturally, the principal difference between English and Russian phonemes does not allow choosing completely identical, phonetically correct sounds. Therefore, LEON's English accent in this song is quite unavoidable. However, to the Russian ear, unaware of the nature of the singer, such singing will remind a cover performance by Baltic, Bulgarian or Chinese artist. Thus, even with the English library: LEON could be of some use in recording Russian songs and its accent will add a touch of familiar color for the Russian audience. Speaking of Yamaha synthesis technology I should note that it's been the first time that we've encountered an error in pitch reproduction of separate long notes, even though no values were entered that deviate Pitch Wheel from the medium position. It seems to appear mainly at the interfaces between consonants and vowels.

For creating the background track a simple Onyx Arranger style was used.
