VOICEPOLISH LAB Murf AI (Voice) Descript (Clean)

Viewers forgive blurry slides—crackly audio gets an instant back-button.

You can’t rent a booth every time a client tweaks a script. Murf reads it in studio quality; Descript wipes breaths, lines up the waveform, and exports on-brand captions. By dinner, the lesson, ad, or podcast trailer sounds like you hired a $200/h engineer—except you pocket the margin.

Promise in one sentence: “From Google-Doc script to broadcast audio in three hours—no mic required.”

Why this sells (three blunt stats)

Audio decides trust

Nielsen 2025: 82 % of learners rate audio quality as the #1 factor in course satisfaction—higher than visuals.

Re-record fatigue

Average creator needs 7 retakes per 10-min script (Thinkific support data). Murf nails it on the first pass.

Editing eats launch dates

Descript’s “Remove Filler” cuts editing hours by 35 % (internal cohort of 3 000 users).

Translation: better sound + fewer retakes + faster edit → courses ship, podcasts publish, ads convert. CFOs like shipped.

Gear roles

Voice Box
Murf AI

120+ voices, pitch & pace sliders, pronunciations dictionary—important when client’s SaaS name looks like a Wi-Fi password.
