This is useful when you need spoken audio for a video, ad variation, product explainer, UGC-style concept, or internal creative draft. Riverflow generates the audio from your written script and selected voice.
What Audio Creates
Audio creates a voice MP3 from a script.
Use it for:
voiceover lines for videos
short ad scripts
product explainers
UGC-style spoken hooks
narration for product demos
reusable audio assets that can later be combined with video
Audio does not automatically assemble a finished video. If you want to add the generated MP3 to a video, use the Video Timeline Editor after the audio is ready.
Create Audio
Open
Audio.Write or paste your script in
Write your script.Choose a character voice.
Preview voices if you want to compare delivery.
Adjust the speed if needed.
Select
Generate audio.Wait for the audio to finish generating.
Play the MP3 result and review it.
Open or download the MP3 where available.
Write A Good Script
Scripts can be up to 3,000 characters.
Write the script exactly as you want it spoken. Keep it natural and easy to read aloud.
Good scripts usually:
use short sentences
avoid overloaded product claims
include punctuation where pauses should happen
spell out unusual words, acronyms, or product names if pronunciation matters
keep the opening line direct
avoid too many ideas in one recording
Example:
Meet the everyday moisturiser designed for busy mornings. It feels lightweight, absorbs quickly, and leaves skin looking fresh without a heavy finish.
If the script is too dense, shorten it before generating. A shorter script is often easier to review, reuse, and time against a video.
Enhance The Script
Use Enhance script when you want Riverflow to improve the script before generating audio.
Review the enhanced version before generating. Check that it has not changed important claims, product names, offers, or approved wording.
Use the original wording instead if the script must be legally or commercially exact.
Choose A Character Voice
Choose the voice that best matches the intended use.
You can preview voices before choosing. Listen for pace, tone, clarity, and fit with the brand.
Consider:
whether the voice suits the product category
whether the delivery feels natural for the channel
whether the tone matches the script
whether the voice will work over the intended video or background audio
Adjust Speed
Use the speed control to make delivery slower or faster.
The supported range is 0.7x to 1.2x.
Use slower speeds when the script contains product detail, legal language, or information that needs to be clearly understood. Use faster speeds for short social hooks or energetic ad variations.
Generate and review the audio after changing speed. A script that reads well at normal speed may feel rushed when sped up.
Review The Output
Generated audio appears in the Audio workspace as an MP3 result.
Depending on the generation state, you may see it as queued, generating, ready, or failed. When the MP3 is ready, use the audio player to listen to it and Open MP3 where available.
Review:
pronunciation of brand, product, and ingredient names
pacing
tone
pauses
whether any sentence sounds unnatural
whether the script still matches approved claims
whether the MP3 is suitable for the video or ad it will support
Use Audio With Video
After generating an MP3, use it in the Video Timeline Editor where audio layers are supported.
Generate the audio.
Review the MP3.
Open the video you want to edit.
Add the audio track.
Align the audio with the visuals.
Preview the full video before export.
Current Limits
Audio currently creates reusable voice audio from scripts.
It is not for:
multi-speaker dialogue workflows
automatic video editing
automatic captions
voice cloning
publishing audio directly to external platforms
For finished video assembly, use the Video Timeline Editor after generating the MP3.
