Text to Speech AI: Turn a Script Into an MP3 Voiceover

Text to speech AI turns written words into spoken audio without a source recording. In Pipe2.ai, Audio Generator takes your script and returns one downloadable MP3. Choose a speech model and voice, describe the delivery, then listen and refine before using the track as narration.

Turn a script into speech in five steps

1. Open Audio Generator and choose a model. Gemini 3.8 Flash TTS is the default, with studio-quality narration in more than 130 languages. Gemini 3.8 Flash-Lite TTS is the faster, cheaper Gemini option for drafts. Eleven v4 is the most expressive option, and MiniMax Speech 2.8 Turbo and HD are also available.
2. Paste only the words to speak into Text. Write in the intended spoken language. Put performance directions in Voice Instructions so they do not become part of the narration.
3. Choose a compatible voice. Gemini supports Auto or a named preset. For MiniMax, choose an explicit voice from its available presets; Auto is not supported for synthesis.
4. Describe the delivery. For Gemini, try a clear direction such as “warm tutorial narrator, measured pace, gentle emphasis.” For MiniMax, start with “slow, calm”: its supported instruction controls are pace and emotion.
5. Generate and review the MP3. Listen for omitted words, pronunciation, pauses, and tone. Change one thing at a time, then generate another take if needed.

Current output contract, checked October 6, 2026: Audio Generator produces spoken MP3 audio from text. Voice choices and instruction controls depend on the selected model.

Try a short narration before the full script

For a first Gemini take, choose Gemini 3.8 Flash TTS, the Kore voice, and these two separate inputs:

• Text: “Welcome to the workshop. Today, we will turn a simple idea into something you can share. Let us begin.”
• Voice Instructions: “Calm tutorial narrator. Warm tone, measured pacing, clear pauses between sentences.”

Keep Enhance prompt enabled if you want Gemini’s delivery directions refined before generation. Disable it to use your instructions unchanged. With Gemini Auto and enhancement off, the voice defaults to Kore; it is not automatically cast. MiniMax uses its supported pace and emotion instructions directly.

This is a practice script, not a claim of a tested output or guaranteed timing. Use it to judge whether the voice and rhythm suit your project before submitting a longer passage.

Match the model to the delivery you need

Gemini offers 30 named preset voices, short style directions, and sounds you place in the text, such as <laugh> or <short pause>. Flash-Lite TTS suits quick drafts; Flash TTS is positioned for studio-quality narration. Eleven v4 adds the widest emotional range with tags such as [whispers]. MiniMax Speech 2.8 offers five exposed preset voices: Turbo is positioned for faster synthesis and HD for final narration. A voice from one model family is not interchangeable with a voice from another.

MiniMax interprets English instruction words such as slow, fast, or quick, plus one supported emotion: happy, sad, angry, fearful, disgusted, surprised, or calm. Do not expect a free-form accent or scene description to provide the same control as Gemini. Accent adherence is not guaranteed.

Review the current credit estimate before running. Gemini models charge for the audio they actually produce; MiniMax and Eleven v4 are billed by characters. Eleven v4 also counts the audio tags sent with your text, and Enhance prompt adds the cost of that refinement step. A short excerpt helps you evaluate delivery before spending credits on a long read.

Direct a character voice for your narration

For a character-led introduction or story, compare two preset voices using the same short line in the intended language. Choose the voice for its sound first, then use Gemini’s delivery instructions to shape emotion and pace. Audio Generator does not offer voice cloning or a named actor’s voice.

Try the line “We found the key. Now we can open the door.” with the direction “quiet excitement, measured pace.” Keep the voice and words fixed for a second take, changing only the direction to “worried, speaking quickly.” These are suggested inputs, not tested recordings; listen for the emotional shift and check that every word remains clear.

For dialogue, generate each character’s lines separately with an explicitly selected voice. Save the model, voice, script, and instructions with each MP3 so you can repeat the setup when revising a line. Listen to adjacent takes together before accepting them; using the same settings does not guarantee an identical performance.

Prepare text that reads naturally

Use short sentences and punctuation to suggest pauses, then judge the actual audio. Names, acronyms, dates, and prices deserve a separate listening check. If a line sounds wrong, spell out an abbreviation or rewrite the troublesome pronunciation in the script.

There is no duration slider: text length and speaking pace determine the voiceover length. For a fixed video slot, measure a sample and revise the script. Generate long narration in logical sections so you can replace one paragraph without repeating the whole read, and keep sections within the selected model’s input limit.

For another language version, translate and edit the script first. Audio Generator infers the language from the supplied text; a delivery instruction is not a translation request.

Use the MP3 as a separate narration track

Download the accepted take and keep it alongside the script. To add it to your clips, provide it as Narration Audio in Video Reel. Add a separate background track with Music Generator when needed, and review the final mix for speech clarity.
