ElevenLabs Integration
Vampro Voice Generator now includes native integration with ElevenLabs. In addition to the built-in 100% offline Kokoro engine, you can toggle to the ElevenLabs workflow to access your custom voice clones, the full ElevenLabs voice library, cutting-edge multilingual models, and fine-grained voice settings — rendering voiceovers directly into your Adobe Premiere Pro sequence or project bins.
1. Connecting Your API Key
Click the ElevenLabs tab at the top of the plugin panel. Paste your ElevenLabs API Key into the field.
2. Loading Voices & Models
Click Load Voices & Models. The plugin connects directly to ElevenLabs' API (api.elevenlabs.io) and populates your dropdown menus with:
- Your personalized, custom cloned voices created in ElevenLabs
- Community & default library voices across diverse accents and tones
- Supported synthesis models: Eleven Multilingual v2, Eleven Turbo v2.5, and Eleven Flash v2.5
3. Fine-Tuning Voice Parameters
Dial in exact performance nuances using the panel controls:
Stability (0.00 to 1.00)
Determines voice consistency. Lower values yield more expressive, dynamic delivery; higher values ensure steady, uniform pronunciation. Default: 0.50.
Similarity / Clarity (0.00 to 1.00)
Controls how closely the output adheres to the original voice profile. Enhances clarity while preventing artifacts. Default: 0.75.
Style Exaggeration (0.00 to 1.00)
Amplifies stylistic emotion, dramatic inflection, and theatrical flair. Default: 0.00.
Speaker Boost (On / Off)
Boosts similarity and presence to make the speaker sound closer to the microphone. Default: On.
Speed & Pitch
Fine-tune speaking cadence (e.g. 1.00x) and pitch offset directly without re-rendering in external audio editors.
4. Direct Timeline Ingestion & Clip Modification
Once your script is ready, click Generate Voice. An interactive audio waveform will render instantly in the preview box. From there:
- Click "Add to timeline" or "Import to Timeline" to place the audio clip right at your current playhead on the active sequence audio track.
- Click "Import to Bin" to store the audio asset cleanly in your Premiere Pro Project Bin for later use.
- To revise a clip, select it on the Premiere Pro timeline and click "Modify Selected Clip" in the panel — the original text and settings will reload automatically so you can tweak and update in seconds.
