Add Voiceover to Video
The edit is finished, the script is written, and the voice is the problem — no quiet room, no microphone, no re-records at midnight. Paste the script into the chat, pick from the available voices and Sparki reads it over the right sections of your video.
How A Script Becomes Narration
From pasted text to a placed, revisable voice track.
Paste The Script, Keep The Meaning
Drop your wording in as it is — a full read, bullet points, notes with timing hints. Sparki turns it into a narration track, lays it across the parts of the video where it belongs and shows the mapping: which line plays over which shot. If you would rather Sparki write the narration from what is on screen, that is its AI commentary capability — this is for scripts you already have.
Pick A Voice That Fits The Channel
Choose from the voices Sparki currently offers, filtered by language and tone — an unhurried read for a clinic explainer, a brisk one for a gadget review. Preview a section in two voices before committing, and swap the whole track to a different voice later without rebuilding anything.
Revise Line By Line, Not Take By Take
Narration edits like text, because that is what it is. Ask to shorten the second sentence, say the price slower, make the closing line warmer — that line is re-read and nothing else moves. No re-recording, no re-syncing, and the timing against your shots adjusts with every revision.
Voiceover Jobs Sparki Covers
Six kinds of narration, all read from your script.
Faceless Channel Narration
Never appear, always publishStock, b-roll and screen-capture channels where the voice carries the channel and the face never shows. Sparki reads the script in the voice you pick and spreads it across the footage, holding sections long enough for the pictures to land between lines. Channels that scale output without recording anything.
Tutorial & Walkthrough Reads
Steps, then what they meanScreen recordings, process videos and how-to demos that need each step named as it happens. Sparki places each instruction over the shot that shows it, so the say and the show stay together, and pads the read where a viewer needs time to follow. Software demos, recipes, setups and repairs.
Clinic & Care Explainers
Calm, plain-language deliveryPractice tours, treatment explainers and pet-care or patient-advice content where trust matters more than hype. Sparki keeps the read even and unhurried, avoids salesy inflection and lets key instructions sit a beat longer than the rest. Vets, clinics and care businesses explaining without alarm.
Product & Promo Reads
Pitch lines over proof shotsProduct close-ups, ecommerce cuts and offer videos where the picture shows the item and the voice sells it. Sparki times each claim to the shot that demonstrates it and keeps the read short enough that the offer lands before the drop-off. Ads and product posts that need a voice fast.
List & Ranking Commentary
Countdowns, picks, comparisonsRanked round-ups, tool comparisons and best-of videos driven by a repeating spoken structure. Sparki keeps the per-item wording parallel, times each entry to its section and holds the same delivery across every item so the format stays tight. Listicle formats where consistency is the style.
Brand & About Videos
One voice for the whole storyCompany intros, founder-story cuts and service overviews assembled from mixed clips that arrive with no narration. Sparki carries one consistent read across mixed footage — phone clips, stills, screen captures — so the piece sounds made once, by one voice, on purpose. Small businesses stitching a story from what they already have.
Who Adds Voiceover With Sparki
Four people with something to say and no recording setup.
Faceless channel operator
Twenty videos a month, zero recordingsRuns channels where the script is the voice. Paste the read, settle on one steady voice and reuse it across every upload, so the catalogue sounds like one person even though nobody ever sat down at a microphone.
Screen-recording tutorial maker
Silent captures, spoken stepsRecords clean walkthroughs but hates their own narration takes. Sparki reads each instruction over the exact step it belongs to, pads where viewers need catch-up time and re-times the read whenever the captures change.
Veterinary clinic owner
Pet-care advice in a calm voiceWants after-visit explainers — dental care, vaccination timing, post-op rules — without turning the consult room into a studio. Sparki delivers each advice script in an unhurried voice over the clinic's own footage, consistent across the whole series.
Gadget reviewer
B-roll cut, script done, voice missingHas the hands-on footage and a finished script but no treated room to record in. Sparki reads it in a brisk reviewer voice over the b-roll, and any late script change is one line to revise instead of a re-record.
How To Add A Voiceover To A Video In 3 Steps
Script in, voice placed, revision by sentence.
- 1
Upload The Video And Paste The Script
Send the cut, then drop the narration text into the chat as it is — full script, bullets or notes. Sparki maps the lines onto the sections of the video where each belongs.
- 2
Pick The Voice And Set The Placement
Choose from the available voices by language and tone, preview a section in two options if you like, and say where the read should start, pause or stop. The narration is generated and laid over those ranges.
- 3
Revise And Export
Change any sentence — wording, pace, warmth — and only that line is re-read. Once the track sits right, export the video with the narration mixed over the original audio.
