Audio is one of the easiest ways to add value to a digital product. A short intro track for course videos, a narrated version of a lead magnet or a voiceover for a product demo can make a simple product feel more polished. Google’s September 2026 AI updates, published on October 2, include two tools aimed at exactly this kind of work.
Lyria 3.5: music from a text prompt
Google says Lyria 3.5 is its most expressive music generation model so far. You can create tracks from text prompts or images in the Gemini app, and it’s also available in Google AI Studio, Google Flow Music and Google Vids.
According to reporting by PPC Land, Lyria 3.5 produces tracks of around two minutes with distinct sections such as verses and choruses, and a companion model creates fixed 30-second clips suited to loops and previews.
When Google launched the earlier Lyria 3 model in the Gemini app, it said all tracks generated there carry SynthID, an imperceptible watermark that identifies Google AI-generated content. Google also said music generation is designed for original expression rather than mimicking existing artists: if you name an artist in a prompt, Gemini treats it as broad inspiration for style or mood.
Possible uses for digital product sellers
- Background music for course lessons, webinars and video sales pages
- Short intro and outro stingers for podcasts or video series
- Ambient tracks to accompany meditation scripts, journals or wellness products
More expressive text-to-speech
The same update introduced the Gemini 3.8 Flash TTS and Gemini 3.8 Flash-Lite TTS models. Google describes them as its most expressive text-to-speech models yet, able to generate custom voices and direct scene dialogue from simple text prompts. They’re rolling out across Gemini Notebook and Google Vids.
Possible uses
- Narrated versions of short reports, checklists or lead magnets
- Voiceovers for product walkthroughs and tutorial videos
- Audio previews of written courses for people who prefer listening
A simple workflow for adding audio to a product
- Start with the script or brief. For narration, finalize and proofread your text first; editing audio later is slower than editing words. For music, note the mood, tempo and length you need.
- Generate a few options. Create several versions and pick the one that fits best. Save the prompts you used so you can create matching tracks later.
- Listen all the way through. Check for odd pronunciations, unnatural pauses, abrupt endings or sections that don’t match the mood.
- Mix carefully. Background music should sit well below any voice. Most video editors let you adjust volume levels.
- Label and store your files. Keep a note of which tool and model created each file and when. If a platform or customer asks, you’ll have the answer.
Keep audio additions modest at first. A short narrated summary or a consistent intro track can lift perceived quality without turning a simple product into a large production. Ask a few customers whether the audio is helpful before adding it everywhere.
Caveats before you sell anything made with these tools
- Check the terms. Read the usage terms for the Google product and plan you’re using, especially if the audio becomes part of something you sell.
- Copyright is limited. The US Copyright Office has concluded that prompts alone don’t make you the author of AI output. Purely AI-generated music or narration may not be protectable, so competitors could reuse similar material.
- Disclose where required. Some marketplaces require AI disclosure. Etsy, for example, asks sellers to disclose when an item was created with the help of AI.
- Don’t imitate real people. Avoid prompts that try to copy a specific artist or a real person’s voice.
- Review quality. Listen to every track and narration in full. Check pronunciation of names and technical terms before publishing.
Is it worth trying?
If you already use Gemini or Google Workspace, these tools are a low-effort way to test audio additions to your products. Google’s announcement doesn’t give pricing or usage limits for these specific features, so check what your plan includes. Keep your own voice and recordings for anything where personal connection matters most, such as coaching content.
