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