AI Voice Over Generator for Videos, Ads & Explainers

An AI voice over generator turns a written script into generated spoken audio that can be downloaded and used in a video, presentation, podcast, or other project.

On getimg.ai you write the script in Create Speech, choose a voice, add inline delivery cues such as [gentle, emotional] to shape the tone, generate, and download the result as a WAV file. Common uses are ad spots, explainer and training video, trailers, documentary narration and social content. If you only need plain speech from a block of text, the AI Text to Speech Generator page covers that workflow.

You write the script for the cut. Paste the script for your edit and use inline delivery cues to adjust tone and pacing before generating the voiceover.

The generator does not analyse your video, detect its runtime or fit a take to an exact duration. If a read comes back longer or shorter than the cut needs, you adjust the script and generate again. In our own October 2026 tests, one 205-character script returned takes of 16.6, 12.7 and 14.8 seconds depending only on the delivery cue.

Yes, and this is the main practical advantage over a recording session. Edit the line, keep the selected voice, and generate a new version instead of scheduling another session. A changed date, a renamed product or a new sponsor line costs one more generation.

Results vary between runs, so a regenerated take is a new performance of the same words rather than a patch dropped into the old one. If only part of a long narration changed, generate that section on its own and place it in your edit.

Speech generated in Create Speech downloads as a WAV file. In our October 2026 runs it came back as 24 kHz mono. Add it to your video or audio editing workflow alongside the picture and the music bed.

No mastering, loudness normalisation or technical delivery check is applied to the generated file, so anything with a broadcast or platform delivery spec still goes through your own audio finishing.

There are 30 voices, 15 male and 15 female, each with a short character descriptor such as warm, firm, bright or breathy. You can listen to the samples before choosing one, and the full library is covered on the AI Voice Generator page.

The voices are multilingual, so the output language follows the language you write the script in rather than a separate language picker. Accent is directed in the script with a bracketed cue, for example [in British accent].

Speech generation is priced per 1,000 characters, so the cost depends on the length of the script you generate. The app shows the credit cost before you generate, and that is the number to go by.

Speech, image and video generation all run on the same getimg.ai subscription and credit system. The other audio tools sit alongside it on the AI Audio Generator page.

Paid plans include commercial usage rights for eligible generated voiceovers under our terms. Rights to scripts, third-party intellectual property, voice likenesses, trademarks, and other protected material still need to be considered.

Voice selection, delivery controls, language support, script revisions, export format and commercial terms. Those six are what separate a tool you can produce with from one that reads text aloud.

On getimg.ai that means a script you write and edit freely, 30 voices with character descriptors, inline bracketed cues for tone and pacing, multilingual output that follows the script, WAV download, and commercial usage rights on paid plans under our terms. Image and video generation run in the same workspace, so the voiceover and the visuals for one project do not need two subscriptions.
