How to Setup Custom Voice Cloning for HighLevel AI Phone Agents

Standard synthetic audio profiles often perform poorly on automated agency calls. When prospective clients hear artificial cadence or metallic artifacts, engagement drops immediately. Custom voice cloning allows agencies to replace generic stock voices with natural recordings of founders, account executives, or administrative staff.

Implementing a custom voice profile helps maintain brand continuity across automated touchpoints. By feeding clean audio samples into the platform's AI engine, automated agents can handle inbound qualification and outbound appointment booking using accurate vocal models.

Enabling Voice Cloning and Accessing Agent Settings

Before configuring custom audio profiles, verify that the voice cloning feature is enabled within your workspace settings. Experimental features and preliminary rollouts must be managed from the agency dashboard.

• Navigate to the agency settings menu and select the Labs section.
• Locate the voice cloning toggle and ensure it is activated.
• Switch to the designated sub-account where your automated calls run.
• Open the AI Agents menu from the main navigation and choose Voice AI.

Once inside the Voice AI dashboard, open an existing phone agent configuration or create a new agent record. The main management interface displays current prompt instructions, interaction rules, and primary audio parameters.

Recording and Uploading Quality Audio Samples

The rendering quality of a cloned voice depends heavily on the clarity of your training data. Low-resolution audio, background noise, or speech distortion will reduce the quality of the final vocal synthesizer.

When gathering source audio samples for your profile, adhere to strict recording standards:

• Record in a quiet room free from echo, air conditioning noise, or ambient office chatter.
• Use a quality dedicated microphone positioned four to six inches from the speaker.
• Ensure only one individual speaks throughout the entire audio sample.
• Maintain a steady conversational pace, neutral inflection, and clear articulation.

Files uploaded directly to the platform should use MP3 or WAV formats under ten megabytes. Alternatively, you can capture audio directly using the browser recorder if your microphone input is properly calibrated.

Configuring Voice Providers and Licensing Rights

Select the voice customization tab within your agent settings and choose the custom creation option. Assign a descriptive name to the audio profile, such as 'Operations Director' or 'Inbound Desk', to organize profiles across multiple client accounts.

You will select between supported voice synthesis engines, including ElevenLabs and Cartesia. Each provider utilizes distinct neural rendering algorithms, so testing short conversational samples across both systems can help determine which option renders your voice sample most naturally.

Confirm the rights authorization prompt inside the setup modal before finalizing the submission. This step records compliance tracking and initiates the neural processing job.

Processing, Testing, and Deploying Cloned Voices

After submitting the sample, your custom profile appears in the voice library under a processing status. Voice model rendering typically takes a few minutes depending on file size and queue volume.

Follow this verification checklist before assigning the cloned voice to live campaigns:

1. Revisit the custom voice section once the rendering status displays as complete.
2. Use the audio preview feature to review synthesized sample phrases for pitch and clarity.
3. Assign the validated voice clone as the active engine on your target phone agent.
4. Save all changes on the primary agent configuration page.
5. Execute a test call using the built-in testing utility to inspect response delivery.

During the interactive test call, test normal conversational branches, common objections, and complex sentences. Confirm that phrase pauses, pronunciation of key industry terms, and transition timing sound natural across extended dialogs.
