Audio Generation - AI Speech, Voiceover, and Sound Powered by CellCog

Create professional audio with AI — voiceovers, music, sound effects, and personalized avatar voices.

CellCog provides three voice providers, each with different strengths. Choose based on your needs:

Scenario	Provider	Why
Standard narration/voiceover	OpenAI	Best voice style control, consistent quality
Emotional/dramatic delivery	ElevenLabs	Richest emotional range, supports emotion tags
Cloned voice (avatar)	MiniMax	Only provider with voice cloning support
Character voice with specific accent	ElevenLabs	100+ diverse pre-made voices
Fine pitch/speed/volume control	MiniMax	Granular voice settings

How to Use

For your first CellCog task in a session, read the cellcog skill for the full SDK reference — file handling, chat modes, timeouts, and more.

OpenClaw (fire-and-forget):

result = client.create_chat(
    prompt="[your task prompt]",
    notify_session_key="agent:main:main",
    task_label="my-task",
    chat_mode="agent",
)

All agents except OpenClaw (blocks until done):

from cellcog import CellCogClient
client = CellCogClient(agent_provider="openclaw|cursor|claude-code|codex|...")
result = client.create_chat(
    prompt="[your task prompt]",
    task_label="my-task",
    chat_mode="agent",
)
print(result["message"])

Voice Providers

OpenAI (Default)

Best for standard narration, voiceovers, and single-speaker content with precise delivery control.

Key strength: Natural-language style instructions — describe the accent, tone, pacing, and emotion you want.

8 built-in voices:

Voice	Gender	Characteristics
cedar	Male	Warm, resonant, authoritative, trustworthy
marin	Female	Bright, articulate, emotionally agile, professional
ballad	Male	Smooth, melodic, musical quality
coral	Female	Vibrant, lively, dynamic, spirited
echo	Male	Calm, measured, thoughtful, deliberate
sage	Female	Wise, contemplative, reflective
shimmer	Female	Soft, gentle, soothing, approachable
verse	Male	Poetic, rhythmic, artistic, expressive

Best quality: cedar (male), marin (female).

Style customization examples:

• "Warm conversational tone, medium pace, slight enthusiasm when mentioning features. American accent."
• "Deep, hushed, enigmatic, with a slow deliberate cadence — true crime narrator style."
• "Heavy French accent, sophisticated yet friendly, moderate pacing with deliberate pauses."

ElevenLabs

Best for emotional delivery, dramatic content, character voices, and audiobook narration.

Key strength: Emotion tags embedded directly in text — [laughs], [sighs], [whispers], [excited], [sarcastic]. Plus 100+ diverse pre-made voices.

Emotion tags (use sparingly — 1-2 per paragraph):

Tag	Effect
[laughs]	Natural laughter
[chuckles]	Soft/brief laughter
[sighs]	Sighing
[gasps]	Surprise/shock
[whispers]	Whispering delivery
[pause]	Natural pause/beat
[sad], [happy], [excited], [angry], [sarcastic]	Emotional delivery

Example prompt:

"Generate speech using ElevenLabs with a warm British male voice: 'And then, just when everyone thought it was over... [pause] [whispers] it wasn't.'"

---

MiniMax

Best for cloned voices (avatars) and fine-grained voice control.

Key strength: MiniMax Speech 2.8 HD — studio-grade audio quality. Supports avatar cloned voice IDs for personalized content, plus 17+ standard pre-made voices with granular speed, pitch, and volume control.

Standard voices include: Deep_Voice_Man, Calm_Woman, Casual_Guy, Lively_Girl, Wise_Woman, Friendly_Person, Young_Knight, Elegant_Man, and more.

Voice settings: emotion (happy/sad/angry/neutral/etc.), speed (0.5–2.0), volume (0–10), pitch (-12 to 12).

Avatar / Cloned Voice

Users can create avatars on CellCog with their own cloned voice. When an avatar has a cloned voice, CellCog uses the MiniMax provider to generate speech that sounds like that person.

How it works:

• The user creates an avatar on cellcog.ai and uploads voice samples
• CellCog clones their voice using MiniMax Speech 2.8 HD
• Any audio request referencing that avatar uses their cloned voice

Example prompt:

"Generate a voiceover using my avatar Luna's voice: 'Welcome to our quarterly update. I'm excited to share some incredible results with you today.'"

This is powerful for creating consistent, personalized content — marketing videos, podcast intros, course narration — all in the user's own voice.

Sound Effects (SFX)

CellCog generates standalone sound effects from text descriptions. Royalty-free, 0.1 to 30 seconds.

Example prompts:

• "Generate a sound effect of heavy rain hitting a metal roof with occasional thunder, 10 seconds"
• "Create a crispy footsteps-on-fresh-snow sound effect, 5 seconds"
• "Generate an echoing door slam in a large empty warehouse"

Tips for better SFX:

• Be specific about textures and environment
• Specify duration when exact length matters
• For ambient audio longer than 30 seconds, generate a short loopable segment and extend with ffmpeg

---

Music Generation

Create original music from text descriptions. 3 seconds to 10 minutes. Royalty-free.

Capabilities:

• Any genre or genre fusion
• Instrumental and vocal tracks (specify if you want vocals)
• Complex arrangements, mood transitions, and energy dynamics
• Describe what you want — the model handles music theory

Example prompts:

• "Create 2 minutes of calm lo-fi hip-hop background music with soft piano and mellow beats, 75 BPM"
• "Generate a 15-second upbeat tech podcast intro jingle"
• "Create 90 seconds of cinematic orchestral music — start soft and inspiring, build to a confident crescendo"
• "Generate a 3-minute pop song about summer adventures with female vocals"

For precise section-by-section control (exact timing per section), describe your composition plan in detail — CellCog handles the structure.

All generated music is royalty-free — use commercially without attribution or licensing fees.

Multi-Language Support

All three voice providers support 40+ languages. Provide speech text in the target language:

English, Spanish, French, German, Italian, Portuguese, Chinese (Mandarin/Cantonese), Japanese, Korean, Hindi, Arabic, Russian, Polish, Dutch, Turkish, and many more.

---

Chat Mode

Use chat_mode="agent" for all audio tasks. Audio generation executes efficiently in agent mode — no need for agent team.

---

Tips for Better Audio

1. Choose the right provider: OpenAI for standard narration, ElevenLabs for emotional/dramatic, MiniMax for cloned voices
2. Provide the complete script: Write out exactly what should be spoken — don't say "something about our product"
3. Include style instructions: "Confident but warm", "slow and deliberate", "with slight excitement"
4. For music: Specify duration, mood, genre, and tempo (BPM if you know it)
5. Pronunciation guidance: For names or technical terms, add hints: "CellCog (pronounced SELL-kog)"
6. For ElevenLabs emotion tags: Use sparingly — 1-2 per paragraph. Tags affect all subsequent text until a new tag.
