ElevenLabs

Create professional voiceovers, clone brand voices, and generate audio content at scale with ElevenLabs.

What This Skill Does

The Challenge: Marketing teams need audio content — video voiceovers, podcast intros, ad narration, social audio snippets — but professional voice recording is expensive and slow. Consistency across content is hard to maintain.

The Solution: ElevenLabs skill provides text-to-speech generation, voice cloning, sound effect generation, and music creation via the ElevenLabs API. Includes voice selection, emotional tuning, multilingual support, and batch generation for marketing workflows.

Activation

Implicit: Activates when user requests voiceover, audio content, speech synthesis, or voice cloning.

Explicit: Activate via prompt:

Activate elevenlabs skill to [generate voice/clone voice/create audio] for [describe content]

Capabilities

1. Text-to-Speech Generation

Convert scripts to natural-sounding audio.

Python example:

from elevenlabs import ElevenLabs

client = ElevenLabs(api_key=os.environ["ELEVENLABS_API_KEY"])

audio = client.text_to_speech.convert(
    voice_id="21m00Tcm4TlvDq8ikWAM",  # Rachel (professional female)
    text="Join thousands of marketers who trust ClaudeKit.",
    model_id="eleven_multilingual_v2",
    voice_settings={"stability": 0.5, "similarity_boost": 0.8}
)

with open("voiceover.mp3", "wb") as f:
    for chunk in audio:
        f.write(chunk)

2. Voice Library

Pre-built voices categorized for marketing use cases.

Marketing voice categories:

Use Case	Voice Style	Example Voice
Ad narration	Authoritative, clear	Adam, Josh
Brand warm	Friendly, approachable	Rachel, Bella
Tutorial	Calm, instructive	Antoni, Elli
Testimonial	Conversational	Dorothy, Thomas

3. Voice Cloning

Create custom voice from audio samples.

Requirements: 1-5 minutes of clean audio, minimal background noise.

Clone workflow:

voice = client.voices.add(
    name="Brand Voice",
    files=[open("sample.mp3", "rb")],
    description="Our brand spokesperson voice"
)

4. Sound Effects and Music

Generate background audio for videos and presentations.

Sound effects:

sfx = client.text_to_sound_effects.convert(
    text="Soft notification chime, professional",
    duration_seconds=2,
)

Prerequisites

ELEVENLABS_API_KEY in .env
Python 3.8+ with elevenlabs package: pip install elevenlabs
ffmpeg for audio processing (optional, for format conversion)

Best Practices

1. Match voice to brand personality Energetic startup voice differs from established enterprise. Test 3-5 voices before committing.

2. Keep scripts under 500 words per generation Longer scripts should be split at natural pause points for better pacing.

3. Store generated audio in assets/audio/ Use naming convention: 20260303-product-ad-v1.mp3

Common Use Cases

Use Case 1: Video Ad Voiceover

Scenario: 30-second product ad needs professional narration.

Workflow:

Write script using copywriting skill (75-90 words for 30s)
Select voice matching brand (warm, professional)
Generate with ElevenLabs API
Adjust stability/similarity for right tone
Export MP3, sync with video in editor

Use Case 2: Podcast Intro Production

Scenario: Marketing podcast needs consistent intro with voice + music.

Workflow:

Write 15-second intro script
Clone founder’s voice (use real recordings as samples)
Generate intro voiceover
Generate background music loop
Mix with audio editor (or ffmpeg)

Troubleshooting

Issue: Voice sounds robotic on complex sentences Solution: Add punctuation for natural pauses. Use <break time="0.5s"/> SSML tags for longer pauses.

Issue: Voice clone doesn’t match source accurately Solution: Provide higher quality samples (studio recording preferred). Increase sample quantity to 3-5 minutes.
