History

On October 18, 2024, Dreamtonics Co., Ltd. posted a thread on Twitter announcing two new voice databases in development for Synthesizer V Studio under the names Felicia and Riku. The second of the pair of voice databases to be teased with a demo song within the thread was Riku, a native Japanese vocal described as a "sensitive, crisp yet brittle-sounding male tenor voice; creating a soft, soporific impression on the listener, with a whispery, feather-like tone suitable for low-mid tempo, gentle, warm emotional and romantic J-pop, K-pop, soul, electronic music and more. The names of his three vocal mode variations Soft, Warm, and Powerful were also revealed. He was announced to be released on October 24.

Riku was released on October 24, 2024 as expected.

Package details as noted:

Riku is a masculine Japanese voice database. As expected of an AI voice database, this enables him to sing with a more human-like, natural, and realistic voice.

Vocal traits as noted:

• Riku's voice was described as having a sensitive, crisp yet brittle-sounding male tenor voice; creating a soft, soporific impression on the listener, with a whispery, feather-like tone.
• He was noted to be suitable for low-mid tempo, gentle, warm emotional and romantic j-pop, k-pop, soul, electronic music.
• He was noted to have a slightly exotic accent, with a not atypically Japanese-sounding voice.
• With Diffusion Probabilistic Models (DPM), Riku can sing more realistically through changes in volume and breath, further enriching singing details, making each singing unique, and providing creators with more options. Through this mode, he can use AI Retakes to create multiple "takes" of a sung section to find an ideal vocal without the need for "laborious tuning". This feature is only available in the Synthesizer V Studio Pro Editor.

Phonetic notes as noted:

• Phoneme format: ARPABET
• Through Cross-lingual Singing Synthesis, Riku can sing in not only Japanese but also in English, Mandarin Chinese, Cantonese Chinese, and Spanish with this feature. Cross-lingual Singing Synthesis is only available in the Synthesizer V Studio Pro Editor.

Vocal Modes as noted (Synthesizer V Studio Pro Editor only):

• Riku comes with three variations:
  • "Soft"
  • "Warm"
  • "Powerful"
