YouTube Shorts
AI Voiceover Guide

YouTube Shorts are short vertical videos — typically 15–60 seconds — that live in an infinite-scroll feed where the first 2 seconds decide whether a viewer stays or swipes. The best AI voice for Shorts is energetic, clear, and front-loads the hook, which is exactly what voices like Liam and Eric deliver. With YTVoice.app at $1.98–$3/hour (~$0.05/minute), a 60-second Short costs about $0.05 to voice.

Shorts reward volume and consistency: channels posting daily grow far faster than those posting weekly. Because audio is the cheapest part of the pipeline at five cents per minute, the format scales without a per-video subscription cost dragging on margins.

On Shorts, retention is everything — the algorithm pushes clips that keep viewers watching to the end and rewatching. The voiceover sets the tempo. A strong pattern:

• Open with the hook, not the intro — name the payoff in the first sentence ("Here's why your videos flop").
• Keep a brisk pace — short sentences, no dead air, energy that matches fast cuts.
• End on a loop or CTA — a line that nudges a rewatch or a follow.

Energetic voices like Jessie and Liam carry this pacing naturally. Slow, measured narration that works for long-form documentaries kills momentum on a 30-second clip.

Short-form rewards voices with personality and energy over slow gravitas. The strongest picks for Shorts:

• Liam — young, high-energy male, the default for punchy hooks.
• Eric — friendly male, great for creator-to-viewer tone.
• Aria — expressive female, ideal for reactions and reveals.
• Jessie — energetic female that cuts through a busy feed.
• Chris — casual male for daily, conversational uploads.

All are premium ElevenLabs voices with a commercial license included, so monetized Shorts are covered out of the box.

Shorts are a volume game, and volume needs cheap audio. At ~$0.05/minute, one hour of audio costs about $3 and yields roughly 120 Shorts at 30 seconds each — enough for four months of daily posting. YTVoice supports up to 300,000 characters per request, so you can batch a whole week of scripts in one go.

Credits never expire and there's no subscription — you pay only for the audio you generate, with crypto or card. New accounts get 1 hour free on Google signup, which is about 120 test Shorts before spending a cent. See pricing for the full breakdown.
