How to Migrate from ElevenLabs to MorVoice in 5 Minutes (Python/Node.js)

The fear of vendor lock-in keeps many engineering teams stuck with legacy providers. You've built your entire infrastructure around one API, hardcoded their specific error handling patterns, and perhaps most importantly, your users are used to specific voices. The switching costs feel insurmountable.

We built MorVoice with a foundational philosophy: **Your code belongs to you.** That's why we created the MorVoice Compatibility Layer—a set of SDK shims that mimic the method signatures of major competitors (ElevenLabs, OpenAI, Google) while routing requests to our high-performance infrastructure.

The 'Shim' Methodology

Usually, migrating an API involves: 1. Rewriting API clients 2. Mapping new error codes 3. Testing edge cases 4. Retraining staff

With MorVoice Compat, it involves changing **one line of code**. We map the input arguments (voice_id, model_id, stability_boost) dynamically to our closest equivalents.

Step 1: The Code Switch (Python)

# ==========================================
# EXISTING ELEVENLABS CODE
# ==========================================
# from elevenlabs import generate, set_api_key
# set_api_key("eleven_key_...")
# audio = generate(
#     text="Hello there!",
#     voice="Bella",
#     model="eleven_monolingual_v1"
# )

# ==========================================
# NEW MORVOICE CODE
# ==========================================
from morvoice.compat import elevenlabs as generate
import os

# Point to MorVoice API key instead
os.environ["MORVOICE_API_KEY"] = "mv_key_..."

# Everything else remains IDENTICAL
audio = generate(
    text="Hello there!",
    voice="Bella", 
    # We auto-map 'Bella' to 'mv_bella_neural'
    model="eleven_monolingual_v1" 
    # We auto-upgrade this to 'mv-turbo-v2.5'
)

Step 2: The Code Switch (Node.js)

// OLD IMPORTS
// const { ElevenLabsClient } = require("elevenlabs");

// NEW IMPORTS
const { ElevenLabsClient } = require("@morvoice/compat-node");

const client = new ElevenLabsClient({
    apiKey: process.env.MORVOICE_API_KEY
});

// No other logic changes needed
const audioStream = await client.generate({
    voice: "Adam",
    text: "This was surprisingly easy.",
    stream: true
});

Step 3: Cloning Verification

The biggest concern is losing your custom cloned voices. You can't just 'export' a neural model from one provider to another. However, you CAN export the **reference audio**.

We provide a `VoiceMigration` tool in our CLI:

# Install the CLI tool
pip install morvoice-cli

# Run the migration wizard
morvoice migrate --source elevenlabs --key-source ELEVEN_KEY --key-target MORVOICE_KEY

# Output:
# > Found 14 custom voices
# > Downloading 'Narrator John' samples (5 files)...
# > Uploading to MorVoice Vault...
# > Finetuning MorVoice Diffusion Model...
# > Verifying SSIM (Structural Similarity)... 0.98
# > Migration Complete.

Feature Mapping Table

| ElevenLabs Usage | MorVoice Equivalent | Behavior |
| :--- | :--- | :--- |
| `stability=0.5` | `style_consistency=0.5` | Exact match |
| `similarity_boost=0.8` | `timbre_focus=0.8` | Exact match |
| `use_speaker_boost=True` | `audio_cleaner=True` | MorVoice is more aggressive on noise removal |
| `<break time="1s"/>` | `[PAUSE=1s]` | Auto-converted |
| `model_id="multilingual_v2"` | `model_id="mv-global-v4"` | MorVoice supports 20 more languages |

Rollback Strategy

Any infrastructure change needs a safety net. Because our SDK is just a wrapper, rolling back is as simple as reverting the import statement.

try:
    import morvoice.compat.elevenlabs as tts
    print("Using MorVoice")
except ImportError:
    import elevenlabs as tts
    print("Fallback to Legacy Provider")

Frequently Asked Questions

Do my cloned voices sound exactly the same?

They will sound like the *person*, but often cleaner. Because we use a Diffusion Transformer instead of a GAN, we typically capture more breath detail and less metallic buzzing. 94% of users prefer the MorVoice render in blind A/B tests.

What about ongoing subscriptions?

You can keep your legacy subscription active while testing. Since MorVoice has no fixed monthly committment for the API (pay-as-you-go), you can A/B test without double-paying for capacity you don't use.

Conclusion: Take Back Control

Vendor lock-in is a choice. By standardizing your audio generation code, you gain the leverage to negotiate better rates, access better models, and ensure business continuity. Migrating to MorVoice takes less time than reading this article.
