AI Voiceover & Text to Speech — Give Your Avatar a Voice
This text to speech tool turns a written script into a natural AI voiceover — and it's built to give your AI avatar a voice. Type your text, pick a voice, and generate expressive speech you can download, or hand off directly to the AI Avatar tool to produce a lip-synced talking video. Beyond single-voice narration, you can assign a different voice to each speaker for multi-speaker dialogue, and use inline audio tags to direct emotion, delivery, pacing, and sound effects. It's the voice half of a complete script-to-talking-video workflow — no microphone, no recording booth.
What Is AI Text to Speech?
Text to speech (TTS) turns written text into spoken audio. Modern AI text to speech is a world away from the robotic readers of old: instead of stitching pre-recorded fragments together, a neural voice model reads the meaning, punctuation, and rhythm of your script and performs it with natural intonation, stress, and timing. The result is a voiceover that sounds like someone reading your words aloud — not a machine spelling them out.
Here that voiceover has a purpose beyond audio: it's designed to power a talking avatar. Generate the voice from your script, then send it to the AI Avatar tool to make a portrait photo speak it with synced lip movement. You can also assign a distinct voice to each speaker for true multi-speaker dialogue, and drop inline audio tags — [excited], [whispering], [sigh] — to direct the performance line by line. When you're done, download the audio or carry it straight into a talking video.
AI Voiceover Features
Natural voices, multi-speaker dialogue, inline audio-tag control, and a direct hand-off to AI Avatar — the voice engine behind your talking videos.
Multi-Speaker Dialogue
Write a conversation, give each speaker their own voice, and the AI generates one seamless track where the voices actually interact — matching prosody, taking turns, and shifting tone between lines instead of sounding like two clips glued together. Perfect for two-host explainers, character scenes, and dialogue you'll later bring to life as talking avatars.
Audio Tags for Emotion and Delivery
Direct every line with inline cues in square brackets. Set the mood with [excited], [whispering], or [sad]; add reactions like [sigh], [laugh], or [gasp]; drop in effects such as [phone ringing]; or shape the pace with [slowly] and [dramatically]. The model treats these as performance direction, so you fine-tune delivery by editing text — never by re-recording.
A Wide Voice Library with Instant Preview
Pick from a broad library of AI voices spanning genders, ages, accents, and styles — warm narrators, upbeat presenters, distinct character voices. Preview any voice in one click before you commit a generation, so you can audition the right tone for your avatar or video first. Each voice stays in character across a whole dialogue.
Speak Many Languages, Auto-Detected
Generate speech across a wide range of languages, with an auto-detect option that reads the language straight from your text. Voice one script in several languages to localize your content, then pair each version with the AI Avatar tool to produce multilingual talking-head videos from the same source.
Built to Give Your Avatar a Voice
This isn't a dead-end audio tool. Every voiceover you make can go straight to the AI Avatar tool, which renders a portrait photo speaking your audio with synced lips. Script here, voice here, and finish as a talking video there — one continuous text-to-video pipeline with no mic, no camera, and no editing suite.
Free to Start, Online, No Install
It all runs in your browser — nothing to download, nothing to install. Type or paste a script, choose your voices, generate, and download the audio for video editors, presentations, or your next avatar. 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 inside your text, wrapped in square brackets, that the model reads as performance direction rather than words to speak. Put a tag at the start of a line to set its overall delivery, or mid-sentence to shift tone on one phrase. In dialogue mode, tags apply per speaker, so each voice carries its own emotion and reactions. Below are the six categories this tool supports, with 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 — Voice Here, Avatar Next
Generate the voiceover on this page, then turn it into a lip-synced presenter video — one workflow, no recording gear.
The voiceover you generate here is the audio that brings an AI avatar to life. Write and voice your script on this page, then open the AI Avatar tool, add a portrait photo, and use that voiceover as the input — the avatar speaks your words with synced lip movement. It's a complete path from written text to a talking video: no microphone to record the voice, no camera to film a presenter, and no editing software to line them up.
Write and Voice Your Script
Type your script here, assign voices, add audio tags for emotion, and generate a natural AI voiceover in the language you need.
Add a Portrait in AI Avatar
Open the AI Avatar tool, upload any front-facing portrait, 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 synced mouth movement — a finished talking-head video, no filming required.
How to Generate an AI Voiceover
From script to a 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 the script. For a conversation, add a line per speaker and give each one a different voice. Insert audio tags like [excited] or [whispering] anywhere you want to direct the delivery.
Choose Voices and Settings
Pick a voice for each speaker from the 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, Download, or Send to Avatar
Generate your audio — most clips finish in seconds to a few minutes depending on length. Play it back, then download it, or send it straight to the AI Avatar tool to turn the voice into a talking video.
What You Can Voice — and Turn Into Video
Voiceovers for avatars, faceless videos, courses, and more — generate the voice, then bring it on screen.
Avatar Presenters and Spokespeople
Voice a digital host, then put it on screen
Script what your on-screen host should say, assign a voice, and generate the voiceover — then send it to AI Avatar to give a portrait a moving, talking face. Perfect for a consistent virtual presenter across explainers, updates, and announcements, voiced and re-voiced as often as your script changes.
Narration and Story Voiceover
One narrator, distinct character voices
Turn chapters, scripts, or articles into narrated audio with a steady narrator voice, and switch to different character voices for dialogue. Audio tags add emotion to dramatic moments, and stability settings keep long narration even — ready to download or hand to an avatar for a reading-on-camera look.
Character and Game Dialogue
Prototype voice lines in minutes
Generate placeholder or production voice lines for characters, NPCs, and scenes. Give each character a distinct voice, direct emotion with audio tags for combat, tension, or comedy, and iterate instantly instead of booking sessions for every script change — then animate a character portrait with AI Avatar.
Course and Training Narration
Localize lessons, then add a presenter
Voice training modules and lessons with a clear, consistent narrator, and generate the same script in several languages for global teams. Pair the audio with AI Avatar to put an instructor on screen — course content with a talking presenter, no filming or studio time.
Ad and Promo Voiceover
Test scripts before you commit budget
Produce voiceovers for video ads, product explainers, and social promos, and generate multiple takes with different voices and deliveries to A/B test messaging. Export the winner, or drop it onto an avatar spokesperson for a face-forward ad — no voice-over booking or recording turnaround.
Faceless and Short-Form Video
Voiceovers for Shorts, Reels, and TikTok
Create narration for faceless YouTube videos, TikToks, and Reels in minutes. Generate the voiceover here, then send it to AI Avatar for a talking-head version, or drop the audio into your editor. Audio tags add the personality that keeps short-form content watchable.
AI Voiceover 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
- For long scripts, split them into sections and generate each separately — shorter passages give the most reliable, consistent 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 matters more than the tag.
- Combine only tags that fit one moment — [excited] [laughs] or [sarcastic] [sigh] stack predictably, while opposite cues like [whispering] [shouting] in a single breath destabilize 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 one bracket tends to confuse the performance.
What to Expect from the Voice Model
How the model performs in real use — its strengths, its limits, and the settings that get the best results.
Where It Excels
- Emotional range: it 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
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 Creative stability, 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 are most consistent when split into sections and generated separately
- This is produced, high-expressiveness generation, not a real-time conversational voice — it's built for finished audio, not live interaction
Best For
- Voiceovers you'll turn into talking-avatar videos
- 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
