How to Generate an AI Voice from Text: A Practical Guide

To generate an AI voice from text in Pipe2.ai, open Audio Generator, paste the script you want spoken, pick a voice (or leave it on Auto), and describe the delivery — tone, accent, pacing, emotion — in the Voice Instructions field. The model reads your text in that style and returns an MP3 you can download or lay over a video. There is no recording session and no voice actor to book; the written text and a short style note are the whole input.

Verified against the live workflow, July 2026: The inputs, voice count, language coverage, style-control behavior, and output format below were checked against the current Audio Generator pipeline. This guide does not assume controls the form does not expose.

How to generate a voiceover in five steps

1. Open Audio Generator. Start from the Audio Generator pipeline. It uses Gemini 2.5 TTS, with 30 voices across 73 languages.
2. Paste your text. Enter the exact words you want spoken. Punctuation matters here — it controls the pauses (see below).
3. Choose a voice. Leave it on Auto to let the model match a voice to your style note, or pin a named voice (Zephyr, Puck, Kore, and others) when you want the same character across several clips.
4. Describe the delivery. In Voice Instructions, write how it should sound: “warm British accent, slow pace with dramatic pauses” or “cheerful and upbeat, brisk”. This is plain-language direction, not numeric sliders.
5. Generate and listen. The output is an MP3. Check the pacing and any tricky names or numbers, adjust the text or the instruction, and regenerate if needed.

Audio Generator takes text, an optional voice, and an optional style instruction, and returns a single MP3. The audio length follows the length of the text — there is no separate duration control — so the script itself sets how long the clip runs.

Write text the model reads well

Because the words are the script, small edits to the text change the result more than anything else. A few habits help:

• Write in short, clear sentences. They pace better than long, clause-heavy ones and give the model natural places to breathe.
• Use punctuation to shape pauses. A period is a full stop, a comma is a brief pause, and an ellipsis is a longer one. Add commas where you want the delivery to slow down.
• Spell tricky words the way they sound if a name, acronym, or number is read incorrectly, then regenerate.
• Keep one voice per character. Pin a named voice for a recurring narrator so the sound stays consistent across clips; use Auto when you just need a good match for a single piece.

For the style itself, describe accent, emotion, and speed together. For example:

Calm, reassuring narrator. A gentle, unhurried pace with clear pauses between sentences. Neutral accent, warm but not overly bright.

Google’s Gemini speech-generation guide recommends this kind of natural-language direction over trying to encode tone as parameters. Style control is expressive but not exact, so treat the instruction as guidance and refine it after listening.

Voices, length, and the limits worth knowing

A few behaviors are easy to trip over:

• Length follows the text. There is no duration dial; a longer script makes a longer clip. Trim or expand the words to change the runtime.
• Very long scripts are chunked. The pipeline splits long text, generates each part, and stitches them, which can leave a slight join at a seam. Breaking a long script into natural paragraphs helps.
• Style is directional, not precise. Instructions steer tone and pace but will not hit an exact emotion or timing every run; regenerate rather than expecting a single fixed result.
• It speaks, it does not sing or score. For music or an instrumental bed, use Music Generator; Audio Generator is speech only.

Put the voiceover into a video

A generated voice is most useful attached to picture. The common path is Audio Generator → Video Reel: create the narration, then add it through Video Reel’s Narration input while background music stays on its own input, so speech and music are mixed with the voice kept in front. If you also want a music bed under the narration, generate one with Music Generator and attach both.

For the full production sequence — planning shots, generating clips, adding narration and music, then captions and branding — follow how to make AI videos. To balance a soundtrack against speech, see how to add music to a video, and to generate the music itself, see how to generate music with AI.

Keep the script, the generated MP3, and any final video as separate assets. That way you can re-voice a line or swap the delivery without rebuilding the rest of the project.
