Compare voice coverage for your markets, whether background music survives, how pronunciation is controlled, whether the script is editable, and whether a human can review.
Smartcat fits teams localizing training, product and marketing video regularly. For lip-synced drama or advertising with performed dialogue, a dubbing studio is still the better fit.
Smartcat has no free-forever plan, but the trial is free: 15,000 Smartwords for 15 days, no credit card.
AI dubbing uses 10 Smartwords per source word, so the trial covers about 1,500 words of dubbed script. Voice previews are free, so try voices before you spend anything.
For narration, explainers, training and walkthroughs, close enough that most viewers do not notice. Emotional performance, such as comedy or raised voices, still sounds synthetic.
The script matters as much as the voice: in 2026, 92% of words translated by Smartcat AI for paying customers were accepted without a single human edit.
Smartcat is SOC 2 Type II compliant. Media is encrypted in transit and at rest, workspaces are isolated, and role-based access controls who can open each project.
On written request, content is deleted or returned within 30 days, so pre-launch recordings do not stay on the platform.
Voice actors and a recording studio, or a dubbing agency. They deliver real performances but are priced per minute and per language, and each new language adds weeks.
The honest trade-off: AI dubbing is time-matched, not lip-matched, so tight close-ups on a speaker's face are better served by subtitles.
AI voice-over covers 35 locales, including Japanese, Chinese, German, Hindi, Korean, French for France and Canada, and US, UK, Australian and Canadian English.
Translation itself covers 280+ languages. Where a locale has no AI voice, export translated subtitles for that market instead.
Yes, in most cases. Smartcat separates speech from background audio and keeps music and effects under the new voice; you can switch the background on or off.
Separation is weaker when music sits in the same frequency range as the voice, or in noisy, echo-heavy recordings.
Use pronunciation control in the Subtitle Editor. Type a phonetic spelling, adjust the stress, or record yourself with Say Your Way, and the AI voice reproduces it.
The subtitle text stays unchanged. Save the fix to your glossary and it applies to future projects automatically.
Yes. Upload the recording and Smartcat creates a timed, speaker-labelled transcript, then translates it.
Export the result as a translated document, as SRT or VTT subtitles if the audio belongs to a video, or as an AI voice track in one of the 35 voice locales.
Dubbing is metered by transcript word count, not by minutes, at 10 Smartwords per source word. Standard translation is 1 Smartword per word.
A long video with little speech therefore costs less than a short, densely scripted one. Plan prices are on the pricing page.
Yes. After dubbing you can download the dubbed video or the voice track on its own.
The separate track is useful when an editor is finishing the video elsewhere, or when you want to add the audio to an existing edit without re-rendering the whole video.
Choose voice-over when viewers should still sense the original speaker: the translated narration plays over the original audio.
Choose dubbing when the original speech should disappear: the AI voice replaces it while music and effects stay. Both start from the same translated transcript.
