AI Text to Speech — Natural AI Voices with Multi-Speaker Dialogue
This AI text to speech tool turns written text into natural, expressive AI voices you can download as MP3. Powered by Eleven v3, ElevenLabs' latest and most expressive voice model, it goes beyond single-voice narration: assign a different voice to each speaker for true multi-speaker dialogue, and use audio tags to direct emotion, delivery, pacing, and even sound effects inline. Choose from 113 voices across 75 languages, then send the generated voiceover straight to the AI Avatar tool to create a lip-synced talking video — a complete script-to-video workflow with no microphone or recording equipment.
What Is AI Text to Speech?
Text to speech (TTS) is technology that converts written text into spoken audio. Modern AI text to speech goes far beyond the robotic voices of older systems: instead of stitching together pre-recorded sound fragments, a neural model analyzes the meaning, punctuation, and rhythm of your text and synthesizes speech with natural intonation, stress, and pacing. This tool is powered by Eleven v3, ElevenLabs' latest and most expressive voice model, which interprets context to decide how a line should actually sound rather than reading it flatly word by word.
What sets this apart from a standard text to speech reader is dialogue. You can assign a distinct voice to each speaker and the model weaves them into a single natural-sounding conversation — matching prosody, handling turn-taking, and shifting emotional tone between lines. Inline audio tags let you direct delivery without re-recording: mark a line [excited], [whispering], or [sad], or drop in nonverbal cues and sound effects. Once your audio is generated, download it as MP3 or send it directly to the AI Avatar tool to produce a lip-synced talking video from the same script.
AI Voice Generator Features
Multi-speaker dialogue, inline audio tag control, 113 voices across 75 languages, and direct hand-off to AI Avatar — all free to start online.
Multi-Speaker Dialogue
Write a conversation, assign a different voice to each speaker, and the AI generates a single seamless audio track where the voices interact naturally. Built on Eleven v3's Text to Dialogue capability, it matches prosody across speakers, handles turn-taking, and shifts emotional tone line by line — producing back-and-forth dialogue that sounds spontaneous rather than two separate clips spliced together. Ideal for podcasts, character scenes, and explainer skits.
Audio Tags for Emotion and Delivery
Direct exactly how each line is delivered using inline tags written in square brackets. Mark a sentence [excited], [whispering], [angry], or [sad] to set the emotion; add [sigh], [laugh], or [gasp] for nonverbal reactions; insert sound effects like [phone ringing] or [rain]; or control pace with [slowly] and [dramatically]. The model reads these cues and adjusts the performance — no re-recording or audio editing required.
113 AI Voices with Instant Preview
Choose from a library of 113 preset AI voices spanning a wide range of genders, ages, accents, and speaking styles — from warm narrators to energetic presenters and character voices. Preview any voice with a single click before you generate, so you can audition the right tone for your script without spending a generation. Each voice keeps its character consistent across an entire dialogue.
75 Languages with Auto-Detect
Generate speech in 75 languages — including English, Mandarin, Spanish, French, German, Japanese, Korean, Arabic, Hindi, and Portuguese — with an auto-detect option that picks the language straight from your text. Produce the same script in multiple languages for localized content without hiring separate voice talent, and pair it with the AI Avatar tool to create multilingual talking-head videos.
Built to Feed AI Avatar
This isn't a dead-end audio tool. Every voiceover you generate can be sent straight to the AI Avatar tool, which renders a portrait photo speaking your audio with synchronized lip movement. Write a script, generate the voice here, and produce a finished talking-head video — a complete text-to-video pipeline with no microphone, camera, or recording equipment at any step.
Free, Online, No Install
Everything runs in your browser — no software to download, no app to install, and no hurdles to start. Type or paste your script, choose your voices, generate, and download the result as an MP3 file ready for video editors, podcast hosts, presentations, or any project. Free to start, with natural-sounding output from the very first generation.
Audio Tags Reference — Direct Every Line
Inline square-bracket cues that tell the AI how to perform each line — emotion, delivery, nonverbal sounds, effects, accent, and pacing.
Audio tags are instructions you write directly inside your text, wrapped in square brackets, that the model interprets as performance direction rather than words to read aloud. Place a tag at the start of a line to set its overall delivery, or mid-sentence to shift tone on a specific phrase. Tags work per speaker in dialogue mode, so each voice can carry its own emotion and reactions. Below are the six tag categories this tool supports, with real examples you can copy.
Emotion
[excited] [happy] [sad] [angry] [surprised] [disgusted] [fearful] [calm] [serious] [confused]
[excited] We just hit our launch target! [serious] Now we protect it.
Delivery Style
[whispering] [shouting] [singing] [laughing] [crying] [mumbling] [yelling]
[whispering] Don't wake them up — [shouting] surprise!
Nonverbal Sounds
[sigh] [gasp] [laugh] [cough] [clearing throat] [sniff] [yawn]
[sigh] It's been a long week. [laugh] But we made it.
Sound Effects
[phone ringing] [door knocking] [footsteps] [rain] [wind] [thunder] [birds chirping]
[phone ringing] Hello? [gasp] You're kidding me.
Accent
[British accent] [American accent] [Australian accent] [Indian accent]
[British accent] Lovely weather we're having today.
Pacing
[slowly] [quickly] [with a pause] [dramatically]
[slowly] Let me explain. [dramatically] Everything changes now.
From Script to Talking Video — Text to Speech Meets AI Avatar
Generate the voice here, then turn it into a lip-synced presenter video — one workflow, no recording equipment.
Text to speech and AI Avatar are designed to work together. The voiceover you generate on this page becomes the audio input for the AI Avatar tool, which animates a portrait photo to speak your words with synchronized lip movement. The result is a complete written-text-to-talking-video pipeline: no microphone to record the voice, no camera to film the presenter, and no editing software to sync them. This is the same script-to-video approach Microsoft describes as a "Text to Speech Avatar" workflow.
Write and Voice Your Script
Type your script here, assign voices, add audio tags for emotion, and generate a natural AI voiceover in any of 75 languages.
Add a Portrait in AI Avatar
Open the AI Avatar tool, upload any front-facing portrait photo, and use the voiceover you just generated as the audio input.
Get a Lip-Synced Video
AI Avatar renders the portrait speaking your audio with synchronized mouth movement — a finished talking-head video, no filming required.
How to Use the Text to Speech Generator
From script to downloadable AI voice in three steps — free, online, no install.
Write Your Script or Dialogue
Type or paste your text. For a single narrator, just write your script. For a conversation, add a line per speaker — you can give each one a different voice. Insert audio tags like [excited] or [whispering] anywhere you want to direct the delivery. Total text can run up to 5,000 characters per generation.
Choose Voices and Settings
Pick a voice for each speaker from the 113-voice library and preview it instantly. Set the language or leave it on auto-detect, and choose a stability mode: Creative for the most expressive, tag-responsive delivery, Natural for a balanced default, or Robust for the most consistent output.
Generate and Download MP3
Generate your audio — most clips finish in seconds to a few minutes depending on length. Play it back, then download the MP3. Use it in a video, podcast, or presentation, or send it to the AI Avatar tool to create a talking video.
What You Can Create with AI Text to Speech
Multi-voice audio for creators, educators, marketers, and developers — from a single script.
Podcasts and Audio Shows
Multi-host episodes without booking a studio
Script a two- or three-host episode, assign each host a distinct voice, and generate a natural back-and-forth conversation with audio tags for laughter, pauses, and emphasis. Produce interview segments, intros, and ad reads without scheduling everyone in the same room or editing separate recordings together.
Audiobooks and Narration
Distinct voices for narrator and characters
Turn chapters, articles, or scripts into narrated audio with a consistent narrator voice — and switch to different character voices for dialogue passages. Audio tags add emotional range to dramatic scenes, while stability settings keep long-form narration even and listenable from start to finish.
Game and Character Dialogue
Prototype voice lines in minutes
Generate placeholder or production voice lines for game characters, NPCs, and interactive scenes. Assign each character a unique voice, direct emotion with audio tags for combat, tension, or comedy, and iterate on lines instantly instead of booking voice-acting sessions for every script change.
E-Learning and Training
Narrate courses in 75 languages
Voice training modules, course lessons, and explainer content with a clear, consistent narrator. Generate the same lesson in multiple languages from one script for global teams, and pair the audio with AI Avatar to put a presenter on screen — no instructor filming or studio time required.
Marketing and Ads
Test ad scripts before you commit
Produce voiceovers for video ads, product explainers, social promos, and slideshow narration. Generate multiple takes with different voices and emotional deliveries to A/B test messaging, then export the winner as MP3 — all without a voice-over budget or recording turnaround.
Social Media and Faceless Videos
Voiceovers for Shorts, Reels, and TikTok
Create voiceovers for faceless YouTube videos, TikToks, and Instagram Reels in minutes. Generate the narration here, then send it to AI Avatar for a talking-head version, or drop the MP3 straight into your video editor. Audio tags add the personality that keeps short-form content engaging.
Text to Speech Best Practices
Writing for Natural Speech
- Write the way people actually talk — use contractions, natural punctuation, and shorter sentences; commas and periods become real pauses in the generated audio
- Spell out anything ambiguous: write 'twenty twenty-six' instead of '2026' and 'doctor' instead of 'Dr.' when you want a specific pronunciation
- Keep each generation under 5,000 characters; for longer scripts, split into sections and generate them separately for the most reliable output
- In dialogue mode, give each speaker their own line and voice so the model can match prosody and handle turn-taking naturally
Using Audio Tags Effectively
- Match the tag to the voice — pick a voice whose natural tone already fits the delivery. A calm narrator won't convincingly [shout], and a high-energy voice won't [whisper] well; the voice you choose matters more than the tags you add.
- Combine only tags that fit a single moment — [excited] [laughs] or [sarcastic] [sigh] stack predictably, while opposite cues like [whispering] [shouting] in one breath produce unstable delivery.
- If a tag sounds muted or ignored, switch to the Creative stability mode and regenerate — Robust keeps the voice consistent but responds least to directional tags.
- Keep it light — one or two tags per line read naturally; stacking five cues into a single bracket tends to confuse the performance.
What to Expect from Eleven v3
How the model actually performs in real use — its strengths, its limits, and the settings that get the best results.
Where It Excels
- Emotional range: the model reads the context of a line and delivers it with fitting tone, emphasis, and timing rather than a flat, uniform read
- Multi-speaker flow: voices in a dialogue match each other's prosody and hand off naturally, so a scripted conversation sounds like one continuous exchange
- Direct control: audio tags set emotion, reactions, and pacing inline — no re-recording or external editing required
Known Limits and How to Work Around Them
- Audio tags don't always trigger on the first try — if a cue sounds muted, switch to the Creative stability mode, make sure the tag matches the voice's character, and regenerate
- Conflicting cues in one breath (like [whispering] [shouting]) can destabilize delivery — combine only tags an actor could perform in a single moment
- Very long scripts produce the most consistent results when split into sections and generated separately
- This is offline, high-expressiveness generation, not a real-time conversational voice — it's built for produced audio, not live interaction
Best For
- Scripts where emotional delivery and tone carry the message, not just the words
- Multi-voice conversations that need natural turn-taking between speakers
- Projects where you'll fine-tune delivery line by line with audio tags
- One script voiced across multiple languages from a single workflow
Not Ideal For
- Real-time or conversational voice agents that need instant response
- Ultra-long single-pass narration without splitting into sections
- Word-for-word robotic reads where no expression is wanted at all
