VoxSprint

VoxSprint is an AI narration tool that turns a finished script into MP3 narration and timed SRT subtitles. A focused web tool that converts a finished script into an MP3 voiceover plus timed SRT subtitles, with selectable voice, speaking style and speed, and word level pronunciation fixes before re-rendering.

VoxSprint is a browser based voiceover generator built around one job: taking a script you have already written and turning it into spoken audio. The workflow starts on a single editor screen with a 300 character script field, a voice selector, a speaking style control and a speed setting. Once the text is in place, the tool renders the narration and hands back two outputs at once, an MP3 file of the audio and an SRT subtitle file with timings that match the generated speech. Having both from one render saves the usual second pass of transcribing finished audio to build captions by hand. The tool assumes the writing is done elsewhere. There is no outline builder, no rewriting assistant and no drafting layer, which suits people who arrive with copy already approved: video editors who need narration for a cut, course creators working from a lesson script, podcasters producing an intro, and social media teams adapting text for short clips. Because the script box is capped at 300 characters, VoxSprint is tuned toward short form work. Longer pieces have to be fed through and joined in a separate editor. The feature that separates it from a plain text to speech box is pronunciation control. If a name, brand or technical term comes out wrong, you select that word in the script and adjust how it should be spoken, then regenerate. That edit lives in the script rather than in an audio waveform, so fixes are cheap and repeatable. The page also mentions an audio tag option, which suggests cues can be added inside the text itself. Among voiceover tools, VoxSprint sits at the light end. It does not try to be a full audio editor or a video production suite, and it does not present itself as a dubbing platform. The proposition is narrow: paste, tune the delivery, export audio plus captions. Payment works on credits rather than monthly tiers, with 2,000 free credits granted after sign in and a $1 pack of 10,000 credits advertised on the page, so cost scales with how much you generate rather than with a recurring plan.
