CVoice Stage | Star Sea Stage
Listen to music and watch videos together—or sing your heart out. Stage is a multiplayer online karaoke room where everyone shares the same video and song timeline. One participant sings at a time while others listen live, chat, and join the song queue.
Videos are loaded by each participant’s browser directly from the original source and are not relayed through Stage. Singing audio is transmitted only in real time within the room; it is not recorded, written to disk, or used for training. Room creators and performers should make sure they have appropriate rights to the videos, backing tracks, and performances they use.

What if your voice fell into another world? Reborn accepts natural speech, humming, whistling, imitations, and other sounds, then uses cues such as rhythm, pitch movement, timbre, dynamics, and valid duration to generate stable otherworld coordinates.
Species, special talents, character gender tendencies, and character age styling are all entertainment-oriented projections of sound and are not used to infer real-world identity. The same audio processed with the same algorithm version produces the same base result.

Atelier feeds cues from a CVoice report—such as timbre composition, voice texture, perceived age, and gender tendencies—into a creative process to generate a personalized portrait card with a name, poetic line, and rarity frame.
The portrait is an artistic expression of voice features, not an assessment of real identity, appearance, gender, or age. Beyond voice portraits, you can also let the microphone drive a nebula canvas or create entirely with your own prompts and reference images in Pro Mode.

CVoice is the starting point of the entire family. Users record or upload a sample of natural speech, and the system organizes voice impressions across dimensions such as pitch contour, brightness, softness, weight, warmth, stability, liveliness, and clarity.
It is designed for lightweight questions such as “What impression does this recording give?” Primary timbre, three-timbre combinations, and perceived gender and age are entertainment-oriented expressions, not ways to confirm real identity or a permanent voice type.
CVoice EchoSea | Echo Sea
EchoSea turns voice-analysis results into a star’s color, size, trajectory, and region. It focuses more on “leaving a brief trace of sound” than on producing a longer analysis report.
Star-sea content expires automatically according to product rules. Interactive voting uses initial verification and anonymous credentials to reduce repeat voting. Users should publish only audio they have the legal right to use.

Insight uses a more complete recording protocol and more acoustic dimensions. It is intended for users willing to record carefully, read the details, and compare different expressive states. It focuses on how sound produces perceptual impressions rather than replacing all information with a single label.
The report indicates recording quality and the range in which its conclusions are credible. Even with more complex algorithms, it cannot serve as an assessment tool for biological sex, actual age, health status, or personality.

FrostNote is interactive pitch training that does not require continuously uploading the live microphone stream to a server. The browser reads audio frames and estimates fundamental frequency, allowing users to hold their voice near a target note and receive immediate feedback.
Microphones, ambient noise, harmonics, and vocal technique all affect detection. It is useful for building an intuitive sense of pitch, but it does not replace a vocal teacher or professional measurement equipment.

MelodyCanvas turns canvas paths into melody: vertical position affects pitch, while movement speed and turns contribute to rhythm and expression. You can start creating from a single line without first learning complex music theory.
Sound is synthesized in the browser, while sharing and reporting are managed by a separate service. The focus is on the creative process, not on classifying the user’s voice.

Arcana combines voice input, tarot spreads, and guided storytelling to help users put vague questions into words and find new perspectives through symbols and text.
Tarot content does not predict a definite future and cannot replace counseling, medical, legal, or financial advice. It is an immersive self-narrative experience.
