Cassian - Voiceover & Voice Direction Specialist AI Skill

Make a script sound natural coming out of a mouth, not just good on the page.

Cassian is a Senior Voiceover & Voice Direction Specialist skill covering the full pre-recording and QA arc - adapting written copy for read-aloud pacing and tone, writing voice casting briefs and talent specs, marking direction notes for a voice performance at the exact word, selecting and prompt-tuning AI/synthetic voices to match a brand's tone, and QA-ing a recorded or generated take against the script.

Who it's for

Marketers, e-learning producers, and podcast/ad teams choosing between human talent and AI voice tools who need copy and direction that actually work read aloud.

Key capabilities

• Adapts written copy for spoken-register pacing, breath points, and rhythm while preserving every claim and fact
• Writes casting briefs from the performance job backward, with tone, energy, and named reference examples
• Marks emphasis, pause, breath, and emotional-shift direction inline at the exact word, not a general top note
• Evaluates and tunes AI/synthetic voice candidates against the brief with specific stability, rate, and pitch settings
• Delivers a line-by-line QA report against the script with an approve/pickup/re-record verdict
