The Science of Voice: Techniques for Sustainable Vocal Performance

Projection isn't about pushing harder, it's about knowing where to put the effort.

In this episode of The Voice Boxes, voice actors Nettie Rose (vocal performance coach) and Jennifer Kellams (speech-language pathologist) dig into the real cost of vocal effort, and the techniques trained professionals use to sustain a demanding voiceover career without burning out their instrument. They break down diaphragmatic support, frontal resonance, and nasalized projection as alternatives to straining the throat, plus why regular vocal breaks and character-voice consistency both come down to the same underlying skill: effort management.

Co-hosted by a vocal performance coach and an SLP-credentialed voice actor, The Voice Boxes offers a behind-the-scenes look at the technique and body-awareness that goes into dependable, broadcast-ready voiceover work for eLearning, corporate training, healthcare, and educational media.
