ElevenLabs V3 Text Optimization

A free, open-source Claude Skill that transforms raw text into ElevenLabs V3 Studio–optimized scripts using audio tags, punctuation engineering, creative spelling, and contextual priming. It automatically analyzes document type, emotional context, and delivery intent to apply V3-specific formatting that improves voice-synthesis quality.

See it in action

Paste flat text; get a script V3 actually performs. Same words — but now the model knows how to say them:

Before — flat text, V3 reads it monotone:

"I told you not to open that door," Sarah said.
"I...I didn't think—"
"You never do!" she shouted.

After — audio tags, emphasis, and per-speaker pacing the engine acts on:

Sarah: [angry] I told you NOT to open that door.

Mark: [nervous] I... I didn't think— [short pause]

Sarah: [shouting] You never do!

The skill also fixes what silently wrecks synthesized audio: it respells names and brands phonetically (ActivTrak → Ak-tiv-trak), spaces out acronyms so they're read letter-by-letter (SOC2 → S O C 2), spells out numbers (10,000+ → over ten thousand), and strips SSML tags V3 doesn't support.

If it saves you a re-render, ⭐ star the repo so other ElevenLabs users find it.

What it does

• Adds V3 audio tags for emotional direction and pacing control ([excited], [whispers], [long pause])
• Applies creative spelling to fix pronunciation of names, brands, and technical terms
• Normalizes numbers, dates, acronyms, and technical terms for clean speech
• Engineers punctuation for natural rhythm and breathing
• Removes incompatible SSML tags (V3 doesn't support <break>, <phoneme>, or XML markup)
• Adapts strategy by content type — dialogue, narration, technical, or dramatic

When it triggers

Phrases like:

• "Optimize for ElevenLabs V3"
• "Make this V3-ready"
• "Convert to V3 format"
• "Add V3 audio tags"
• "Prepare this for TTS"

…or any text intended for ElevenLabs V3 voice generation.

Installation

Option A — Install the skill folder (Claude Code)

Copy the skill folder into your Claude skills directory:

# Personal (all projects)
cp -r elevenlabs-v3-text-optimization ~/.claude/skills/

# Or project-scoped
cp -r elevenlabs-v3-text-optimization /path/to/project/.claude/skills/

Restart Claude Code (or start a new session) and the skill will be available.

Option B — Use the packaged .skill file

Download elevenlabs-v3-text-optimization.skill and upload it wherever packaged skills are accepted (e.g. Claude.ai skill upload).

Usage

Once installed, just ask Claude to optimize text for V3:

Optimize this for ElevenLabs V3:

"Welcome to the show. Today we're talking about AI."

Claude applies the skill automatically and returns a V3-ready script with audio tags and pacing.
