Paste a script and get natural voiceover in multiple voices, with matching SRT and VTT captions. Assign a voice per speaker. Free AI text to speech.
Try asking
A voiceover is rarely the last step. You need the audio, then captions that line up with it, then the whole thing sitting under video. Getting the audio is the quick part. Lining the rest up afterwards is what takes the evening.
Paste your script into Chat Octopus and ask for it read aloud. You get natural speech in your choice of voice, as a downloadable audio file with no watermark. The script and the audio both stay in the thread, so a second take is one sentence, not a new project.
You direct the read the way you would direct a voice actor, in plain English. "Read this slowly, hushed and conspiratorial, like telling a ghost story by candlelight." One line like that in front of your script shapes the whole take. Name a place rather than a region and the accent lands closer: a soft Edinburgh lilt gets you further than "a British accent". When a single moment needs to turn mid-line, mark it where it happens: [whispers] Did you hear that? Keep those sparse, because a tag on every line starts to sound robotic.
You can also give each speaker their own voice. Label the parts in your script and Chat Octopus assigns a different voice to each label, so a two-person dialogue comes back as one piece of audio instead of two takes you have to line up afterwards.
Every voiceover comes back with captions that already match it. Chat Octopus transcribes the speech it just generated and returns SRT and VTT files at both word level and segment level. Word level is what you want for captions that pop one word at a time. Segment level is what you want for a subtitle track. You never asked for them separately, and you never have to time them by hand.
Because Chat Octopus is one copilot rather than a single-purpose tool, the voiceover keeps moving. Lay it over your footage, burn in the subtitles it already generated, and download the video. Creators use this for narrated explainers. Course builders use it for lecture audio. Marketers use it to voice an ad script and hear it in a few different voices before picking one.
