Exciting news for video creators! The SundaySky team recently released Custom AI Voices, a powerful new capability that lets organizations quickly bring their own teams’ voices into video without the need for new audio recordings. This release answers one of the most requested features from our customers and empowers enterprise organizations with a new way to add a personal touch to their personalized videos at scale.
What is a Custom AI Voice?
Simply put, a Custom AI Voice is a digital replica of a real person’s voice. By analyzing a short voice sample, SundaySky’s AI learns to match the speaker’s tone, timbre, pronunciation patterns, and vocal inflections. Once trained, the Custom AI Voice can generate narration that sounds strikingly similar to the original voice, complete with natural pacing, rhythm, and adaptability across different types of scripts.
Why we developed Custom AI Voices
Customers have been clear: they want more options, representation, and efficiency in how they create video.
With Custom AI Voices, organizations can:
- Personalize at scale – Familiar voices from your own team narrate videos, building stronger connections and trust.
- Expand representation – Reflect more voices, accents, and dialects that resonate with your audience.
- Accelerate production – Skip costly studio recordings and the logistics of live voice talent. AI-generated narration is faster, flexible, and cost-efficient.
- Adapt across languages – Generate narration in multiple languages, even if the original speaker isn’t fluent, while preserving their unique vocal identity.
- Handle scale effortlessly – Produce high volumes of narrated content that would be impossible with human-only voiceover workflows.
How it works
Custom AI Voices are created by simply recording a voice sample within the SundaySky platform. Once trained, the voice can be selected dynamically within a video template. Contributors can even clone their own voices through SundaySky Amplify, enabling truly personalized video creation without requiring technical expertise.
Use cases across the organization
The applications for Custom AI Voices span every function in a business:
- Sales & success: Prospecting, proposals, meeting recaps, executive business reviews, renewal notifications, upsell campaigns.
- Training & education: Product training, employee onboarding, and ongoing L&D programs.
- Marketing & communications: Product launches, newsletters, organizational updates, earnings call recaps.
From sales directors to CEOs, account managers to HR leaders, and even presenters, Custom AI Voices make it possible for anyone in the organization to narrate content that feels personal and authentic.
