Ruten
A structured, self-paced voice feminization course based on L's Voice Training Guide.
What is this?
Ruten is a free, interactive voice training course that takes the concepts from L's Voice Training Guide and organizes them into a structured weekly curriculum with built-in practice tracking, timed exercises, and audio recording.
The original guide lays out a progression through four difficulty levels covering eight core vocal elements. This course turns that progression into concrete weekly lessons with daily practice routines you can follow at your own pace.
What does it cover?
The course spans 10 weeks across four levels:
Level 1 — Foundations
Reference voice selection, baseline recording, vocal tract length, larynx control, pitch fundamentals, and resonance layering.
Level 2 — Intermediate
Open quotient and breathiness control, intonation patterns, and expressive speech melody.
Level 3 — Advanced
Articulation and vowel/consonant brightness, vocal twang for clarity and projection, throat closure and nasality control.
Level 4 — Mastery
Mantra phrase exploration, structured feedback and polishing, performance preparation, and real-world carryover.
How does it work?
- Each week has lesson writeups explaining the concepts and technique.
- Daily practice sessions with timed exercises, recording prompts, and reflection tasks.
- Your progress is tracked locally in your browser — nothing is sent to a server.
- Work at your own pace. The weekly structure is a guide, not a deadline.
