How to Voice a Short Promo Video or In-Store Audio Loop with an AI Voice Generator: A Guide for Winter Park's Park Avenue Shops

Park Avenue in Winter Park has a character all its own: boutiques with carefully chosen stock, restaurants with sidewalk tables, and galleries that reward a slow walk. Those businesses share a marketing challenge. They need short videos that capture the feel of the place for social media, and many would like a gentle voice in the shop itself announcing a trunk show, a new collection or an opening reception. Hiring voice talent for every update is not realistic for a small storefront.

An AI voice generator solves that by turning a written script into natural narration in minutes. This step-by-step guide shows how to create a voiceover for a short promo video or an in-store audio loop using Adobe Firefly, then answers the practical questions that come up along the way: commercial rights on free plans, bilingual versions, tricky names and how the alternatives compare.

What you need before you start

You need three things: a short written script, a free Adobe account, and the video or audio player you plan to use. Adobe's Firefly AI voice generator is designed for voiceovers in videos, presentations, marketing content and podcasts, creates dialogue in more than 20 languages with multiple accents, and includes free daily generations with an Adobe account. Finished narration downloads as a WAV file, which works in nearly every video editor and most in-store audio systems.

Write a script that sounds right out loud

A voiceover script should be written for the ear, not the eye. Keep sentences short, put the most important detail first, and read the script aloud yourself before you generate anything. For a fifteen-second social promo, two or three sentences are plenty. For an in-store loop, write a few short messages that can play in rotation rather than one long announcement, so customers who walk in midway still catch a complete thought.

Spell out anything that should be spoken a particular way: write times as you would say them, spell an unusual designer or artist name phonetically if needed, and avoid symbols the voice might read literally.

How long should each voiceover be?

Shorter than most owners expect. A social promo works best at roughly fifteen to thirty seconds, which is about two to four spoken sentences, because viewers decide within the first few seconds whether to keep watching. Lead with the hook, such as a new arrival, an opening night or a seasonal menu, then give one detail and one clear next step, like visiting the shop on Park Avenue this weekend.

In-store messages should be shorter still. A loop of three or four brief announcements, each played between songs, feels welcoming rather than intrusive. Short files are also easier to manage: when a promotion ends, you replace one clip instead of regenerating a long recording, and each regeneration uses less of your free daily allowance.

Step by step: creating the voiceover in Firefly

1. Open the voice generator. Sign in with your Adobe account and open the AI voice generator in Firefly.

2. Paste your script. Add the text for one clip or one in-store message at a time, so each file stays short and easy to replace.

3. Choose the language and accent. Pick the language your audience speaks and an accent that suits your brand. Firefly supports more than 20 languages with multiple accents.

4. Select a voice. Browse voices by tone, accent and age and pick one that matches your shop. A gallery may want a calm, measured read; a boutique launching a summer line may want something brighter. To stay within Adobe's commercial-safety statement, choose a voice from the Firefly Speech Model rather than a partner model.

5. Adjust the delivery. Use the editing controls to shape how the line is spoken, then generate a take.

6. Listen and refine. Play the result through a phone speaker and, for in-store use, through the speaker you will actually use. If a name sounds wrong, respell it phonetically and regenerate.

7. Download the WAV file. Save the narration with a clear file name, such as the promotion and date, so you can find it later.

8. Add it to your video or player. Import the WAV into your video editor under your footage, lower any music beneath the voice, and add captions. For in-store audio, load the files into your playlist in rotation with music.

If you want to follow these steps now, open the AI voice generator from Adobe Firefly in another tab and work through your first script while you read.

Can you use the voiceover commercially on a free plan?

With Firefly, Adobe states that voiceovers generated with the Firefly Speech Model are safe for commercial use, and free Adobe accounts receive free daily generations, which makes it a sound starting point for promotional audio. Firefly also offers voices from a partner model, ElevenLabs Multilingual v2, and Adobe's statement attaches to its own model, so check partner terms if you choose one of those voices. Free daily generations suit a steady rhythm of a few clips at a time rather than a large batch in one sitting.

Other tools vary as of 2026. TTSMaker states that users have 100% commercial usage rights for generated audio, under a non-exclusive, worldwide, perpetual license that grants usage rights rather than copyright. ElevenLabs says its free plan cannot be used for any commercial purpose and requires published free-plan content to include "elevenlabs.io" or "11.ai" in its title, while all paid plans include a commercial license unless you use Beta Services. Narakeet's free account does not allow commercial use. Google Cloud Text-to-Speech offers monthly free characters only with billing enabled on a Google Cloud account, and it is a developer API rather than a creator tool.

How do you make English and Spanish versions?

The cleanest approach is to translate the script fully and generate each language separately, choosing a voice suited to each. With 20+ languages and multiple accents in Firefly, you can produce an English promo and a Spanish promo from the same footage, or alternate short messages in each language in your in-store rotation. Have a fluent speaker listen to the Spanish version once before it goes public.

If you ever need several languages inside a single file, other tools document that. Narakeet describes switching speakers per language, assigning a different speaker to a passage, or using a polyglot voice, with a credit-free preview. Google Cloud's SSML lang tag mixes languages in one request, but it requires a developer.

How do you get artist names, product terms and acronyms right?

In Firefly, the practical method is to write the word as it should sound, separate acronym letters with spaces or periods, and preview every take. Gallery and fashion scripts are full of names from many languages, so a phonetic spelling is often the quickest fix. Tools with formal pronunciation features include Google Cloud, whose SSML supports say-as, sub, phoneme tags and a custom pronunciation dictionary, and ElevenLabs Studio, which saves alias and phoneme rules to a project dictionary (phoneme tags only work with Eleven Flash v2). Those are useful for long, technical narration, but most short promos do not need them.

A free voiceover for a gallery or nonprofit explainer video

A gallery's exhibition explainer or a nonprofit's program video can follow the same steps. Because it will be public, use a free plan that permits that use: Firefly's free daily generations with Firefly Speech Model voices are the best first choice, and TTSMaker, with a free limit of 20,000 characters per week and files stored for about 30 minutes, is a zero-cost backup. Avoid the ElevenLabs and Narakeet free plans for published videos.

Tips for in-store audio and short promos

• Keep in-store messages under twenty seconds. Shoppers are moving, and short messages repeat gracefully.

• Match the voice to the room. A quiet gallery suits a softer read than a busy restaurant.

• Use one consistent voice. Choosing the same Firefly voice for every message makes your shop sound recognizable.

• Caption your social videos. Many people scroll with sound off, so captions should match the script.

• Date your files. Name each WAV by promotion and date so outdated announcements do not slip back into rotation.

• Refresh seasonally. Rewrite messages for each season or event rather than letting one loop run for months.

Wrapping up

Creating a professional voiceover no longer requires a studio. For Winter Park boutiques, restaurants and galleries, Firefly offers a straightforward path: write a short script, choose a voice and accent, refine the delivery, download a WAV file and drop it into your video or store playlist. Its free daily generations and the commercial-safety statement for the Firefly Speech Model make it a practical place to begin.

Start with one message for this weekend's window display, listen to it in the shop, and build your library of voiceovers from there.
