Complete All-in-One Singing Straw & Vocal Trainer Kit: AirVō Pro by Dr. Voice LLC is the world's first professional all-in-one SOVT (Semi-Occluded Vocal Tract) singing straw system, designed as a high-performance voice straw and vocal trainer for building a better voice. The kit includes five stainless steel singing straws (2–6 mm), the innovative FlowCase, cleaning brush, velvet pouch, lanyard, and user manual—everything neatly packed for easy storage and travel. Ideal for vocal training, voice therapy, teaching, and daily voice use.
11 Adjustable Resistance Levels for Vocal Warmups & Training: Unlike standard singing straws, AirVō Pro functions as a precision vocal trainer with 11 distinct resistance levels. Use each voice straw individually (2–6 mm), combine straws to create larger bores (up to 11 mm), or train directly with the FlowCase. This wide range supports gentle vocal warmups, targeted voice therapy, and intensive breath and voice strengthening—delivering three times more resistance options than typical singing straw tools.
Innovative Portable Design with Nested Singing Straws: All five stainless steel singing straws nest inside each other and slide seamlessly into the FlowCase, keeping the full vocal trainer system compact and organized—no loose parts, no lost pieces. This first-of-its-kind nesting design allows the FlowCase to also function as an 18 cm voice straw with an 8 mm inner diameter. Lightweight and travel-ready, AirVō Pro is easy to carry with the velvet pouch and lanyard for consistent vocal training at home, in the studio, classroom, or clinic.
Water Resistance Sound Therapy & Biofeedback: The FlowCase or 16 cm singing straw can be submerged for water resistance (Lax Vox–style) training, supporting sound therapy that reduces vocal strain and promotes efficient phonation. Used dry, the FlowCase acts as a precision vocal trainer with 4 adjustable resistance holes. Airflow can be directed under the nose to provide tactile biofeedback for improved breath control, resonance awareness, and a better voice.
Designed for Voice Performance, Teaching & Therapy: AirVō Pro is a versatile singing straw and vocal trainer for performers, educators, speakers, and clinical voice training. SOVT exercises support efficient phonation, improved resonance, and reduced vocal effort—helping build a better voice with consistent use. Trusted by vocal coaches and voice professionals, it's ideal for daily vocal warmups, training, and long-term voice care.
