Voiceover Lab
Audio Expansion. Voiceover Lab is part of Chat Video Pro’s Audio Expansion. It is included with the Creator Bundle and Creator Pass, and available as a DLC add-on for Base. Generations bill to your own fal.ai account at wholesale rates — same as the rest of Studio.
Voiceover Lab turns a script into spoken narration without leaving Premiere. Write (or paste) copy, pick a catalog voice or one of My Voices, generate, then Add to Chat and drop the take onto your timeline.
When to Use Voiceover Lab
Narration and explainers — product demos, tutorials, ads, social VO
Temp VO for picture lock — placeholder reads before a talent session
Consistent brand voice — reuse a cloned voice across projects
Avatar pairing — the same voice layer powers Avatar Studio when you need a talking head on camera
Voiceover Lab is chat-first. Results go to Add to Chat — there is no Place on timeline button in this workflow. Drag the audio from chat into Premiere (or place from Library) when you’re ready.
Getting Started
Step 1: Open Voiceover Lab
Open Chat Video Pro (Window → Extensions → Chat Video Pro)
Click Studio → Audio department
Click the Voiceover Lab card
You’ll see three steps: Script · Voice · Generate.
Step: Script — Write your script
Type or paste your narration into the script editor.
The Script step allows up to about 10,000 characters for drafting.
Tap the sparkle (Optimize script…) to tighten pacing, clarity, or delivery notes, then review and keep or dismiss the suggestion.
Click Continue.
Write the way you want it spoken. Short sentences and explicit pauses (“…”) read more naturally than dense paragraphs.
Step: Voice — Choose a voice
Browse the voice catalog (filter by gender, accent, tone, use-case, or provider).
Preview a voice before you commit.
For MiniMax voices, choose HD or Turbo quality when offered.
Open My Voices to use a cloned voice, or create one from a recording / upload (aim for a clean sample of about 10+ seconds).
Character limits at generate time (enforced for the selected voice’s provider):
ElevenLabs
5,000
MiniMax
10,000
If Generate is blocked, shorten the script or switch to a provider with a higher cap.
Cloned voices can expire on the provider side after roughly a week of inactivity. If a custom voice fails with a “not found” style error, Voiceover Lab can refresh/reclone automatically when you regenerate — keep your original sample handy.
Click Generate Voiceover when the script and voice are set.
Voice cloning (My Voices)
Clone a custom voice from a short sample, then use it like any catalog voice in Voiceover Lab (and in Avatar Studio — they share the same voice layer).
Requirements: a clean audio sample of at least 10 seconds, and a connected fal.ai key (Settings). Cloning and speech generations bill to your fal.ai account at wholesale rates.
When to clone a voice
You want narration that sounds like you (or a client / talent) instead of a preset
You need the same voice across Voiceover Lab takes and Avatar Studio talking heads
You’re building a reusable brand VO without booking a booth every time
How to clone a voice
Step 1: Open the clone flow
Open Voiceover Lab → go to the Voice step
Click Clone Voice (primary green button), or open Manage Voices and switch to the add/clone flow
The Manage Voices modal title explains the rules: clone from a 10s+ sample; cloned voices expire after 7 days and auto-reclone on use.
Step 2: Name the voice
Give it a clear name (e.g. “Client Brand VO” or “Client – Sarah”)
Optional tags help you find it later under My Voices
Step 3: Provide a sample (pick one source)
Record
Use the in-panel recorder. A guided transcript appears so you have something natural to read — click Start recording, speak clearly, stop when you have 10+ seconds.
Upload
Choose an audio file (common types: MP3, WAV, M4A, OGG).
Sample must be at least 10 seconds. Shorter clips are rejected with a message showing your duration. Prefer a quiet room, dry mic, no music bed, and no heavy reverb.
Step 4: Clone
Confirm the sample looks ready (duration ≥ 10s)
Click Clone Voice (shows Cloning… while it runs)
When it finishes, the voice appears under My Voices
Step 5: Use it
On the Voice step, filter to My Voices (or find the card in the grid)
Select the cloned voice (preview if available)
Continue with your script and click Generate Voiceover
Managing cloned voices
In Manage Voices you can:
Browse My Voices (N)
Audition a sample (only one plays at a time)
Delete a voice you no longer need (confirm in the panel — no system dialog)
Expiry and auto-refresh
Cloned voices are stored with the AI provider and typically expire after about 7 days.
Chat Video Pro keeps your local sample so it can auto-reclone when you generate and the old voice id is gone
If a custom voice fails with a “voice not found” style error, try Generate again — the panel should refresh the clone and retry
Keep a backup of the original sample outside the panel if the voice matters for long-running projects
Best practice: re-clone (or generate once) with an important voice every few days during active work so the provider copy stays fresh — or just rely on auto-reclone and keep the sample file.
Tips for a good clone
Read in a natural speaking voice — not whispered, not shouted
One speaker only; avoid background TV, fans, or music
Phone voice memos are fine if the room is quiet and the level isn’t clipping
Longer than 10s is OK; clarity matters more than length past the minimum
Name voices by person + use case so you don’t mix “temp booth” with “final brand”
Cloning troubleshooting
“Sample must be at least 10 seconds”
Record/upload a longer clip
Clone fails / can’t read media
Re-upload the file, or re-record in the panel (avoid broken paths)
Clone button stays disabled
Add a name, attach a valid sample ≥ 10s, confirm fal.ai key
My Voices is empty / filter hidden
You haven’t cloned yet — use Clone Voice
Custom voice fails on Generate
Usually expiry — generate again to auto-reclone; keep the original sample
Clone sounds wrong / noisy
Re-record dry and quiet; don’t use music beds or heavy FX
Using a clone in Avatar Studio
Cloned voices live in the shared voice library. After you clone in Voiceover Lab (or Manage Voices), open Avatar Studio, pick Script + voice, and select the same voice from My Voices so the talking head matches your VO.
Step: Generate — Result
Preview the take in the result player
Try Again — same voice, new take
Try Different Voice — jump back to Voice without losing the script
Add to Chat — hand off into the conversation / Library for timeline use
There is no Place on timeline control in Voiceover Lab by design.
Tips for Best Results
Optimize after you have a solid draft — not before you’ve decided what the VO must say.
Match provider to length: long scripts often fit MiniMax’s higher cap; short ads fit either.
Clone from quiet, dry recordings — music beds and heavy reverb confuse the clone.
For Avatar Studio, generate or pick the voice here first, then reuse it in the talking-head workflow.
After Add to Chat, place VO on a dedicated track and nudge to picture in Premiere.
Troubleshooting
Generate disabled
Script over the provider cap (5k / 10k), empty script, or no voice selected
Clone rejected
Sample too short (< ~10s), too noisy, or wrong file type — record/upload again
Custom voice suddenly fails
Provider expiry — regenerate to refresh; keep the original sample
No Place on timeline button
Expected — use Add to Chat, then drag into Premiere
Engine errors
Check fal.ai key + balance in Settings → Usage
