What are stock AI voices?

Stock AI voices are ready-to-use, pre-built voices available in SundaySky’s AI voiceover library. They’re designed to sound natural and professional, with options across multiple languages, tones, and styles, so narration can be added to any video instantly.

What are custom AI voices?

A custom AI voice is a digital replica of a real person’s voice. AI analyzes a sample provided by the original speaker, learning tone, timbre, pronunciation, inflection, and style. Once trained, the custom AI voice can generate narration that sounds nearly identical to the original, allowing authentic communication to scale across all videos.

How do custom AI voices work?

A speaker’s voice is captured once and then replicated with AI. From there, narration can be generated and updated instantly via text-to-speech, without repeated recording sessions or studio time.

What makes custom AI voices different from stock AI voices?

Stock AI voiceovers for video are ready-made and ideal for speed and variety. Custom voices replicate executives, ambassadors, or team members, enabling authentic, trusted narration at scale.

Can AI voices be used in multiple languages?

Yes. Stock voices are available in multiple languages, and custom AI voices can speak languages the original speaker may not be fluent in.

How much do AI voiceovers for video cost?

Stock AI Voices are included at no cost. Each SundaySky subscription tier comes with an allotted number of Custom AI Voices, with additional voices available for purchase.

Who can benefit from custom AI voices?

Sales, marketing, training, customer success, and internal communications teams all use AI voices to scale video narration, increase engagement, and save production time.

Can stock and custom AI voices be personalized for each viewer?

Yes. With SundaySky, narration can be personalized with dynamic data, like a viewer’s name, location, or product details, without losing natural flow.
