AI Text to Speech: Free-to-Try AI Voice Generator for Voiceovers
VdoBloom’s AI text to speech tool turns a written script into a spoken voiceover in your browser. Paste your text, choose a voice, and the audio is generated in the cloud in seconds, ready to play and download as an MP3. It works as an AI voice generator for video narration, YouTube and TikTok voiceovers, explainers, ads, e-learning and presentations, with no microphone or editing software.
Is it free? You can try it with the 10 free credits every new account gets, which covers a voiceover of up to 1,000 characters on Google Gemini 3.1 Flash TTS or xAI TTS. Pricing is per length: 6 credits per started block of 1,000 characters on Gemini or xAI. Playback in the browser works on every plan, and MP3 downloads are included with any paid plan, starting with the Lite pack of 300 credits for $19.50 one-time (credits never expire) or $15 a month.
You get 36 named voices across two engines: 30 voices on Gemini 3.1 Flash TTS and six expressive voices on xAI TTS, with a language menu of 24 languages, including Hindi, Tamil, Spanish, French, Japanese and Arabic. The exact credit cost for your text appears before you click Generate.

Why use this tool
36 named voices on two engines
Gemini 3.1 Flash TTS offers 30 voices with different tones and pitches; xAI TTS adds six expressive voices. Switch engines and voices to compare reads of the same line.
24 languages in the picker
English plus ten Indian languages (Hindi, Tamil, Telugu, Marathi, Bengali, Gujarati, Kannada, Malayalam, Punjabi, Urdu) and 13 more, from Spanish and Portuguese to Japanese, Korean and Arabic.
Clear per-length pricing
Cost is calculated per started block of 1,000 characters and shown before you generate. There is no subscription required and no per-voice surcharge.
Ready for video
The MP3 drops straight into VdoBloom’s video tools or any editor, so a script can become a narrated video in one workspace.
Which AI voice engine should you use?
Both main engines are priced the same, so the choice comes down to voice style and script length. Gemini 3.1 Flash TTS has the largest voice list and broad language coverage. xAI TTS has fewer voices with a more expressive delivery, which suits hooks, ads and short social clips.
A simple way to decide: write your script once, generate the first two sentences with two or three voices from each engine, and keep the one that fits your brand. A two-sentence test costs 6 credits per voice.
| Engine | Voices | Language control | Credits per 1,000 characters | Best for |
|---|---|---|---|---|
| Gemini 3.1 Flash TTS | 30 | 24-language menu or Auto | 6 | Narration, explainers, multilingual scripts (up to 4,000 characters per generation) |
| xAI TTS | 6 (una, leo, eve, ara, sal, rex) | 24-language menu or Auto | 6 | Expressive hooks, ads, short social voiceovers |
How much does AI text to speech cost on VdoBloom?
Text to speech is billed by the length of your script. Every started block of 1,000 characters (letters, spaces and punctuation) costs 6 credits on Gemini or xAI, so a 1,001-character script counts as two blocks.
With the Lite pack (300 credits for $19.50 one-time, or $15 a month), you can voice 50 blocks of 1,000 characters on Gemini or xAI. One-time credits never expire; subscription credits reset each billing cycle. Failed generations are refunded automatically.
| Script | Characters | Blocks billed | Credits (Gemini or xAI) |
|---|---|---|---|
| Short ad hook or caption | 300 | 1 | 6 |
| One-paragraph voiceover | 1,000 | 1 | 6 |
| Product explainer | 2,500 | 3 | 18 |
| Long narration (split into two Gemini runs) | 6,000 | 6 | 36 |

Tips for natural-sounding AI speech
The voice reads exactly what you write, so a few edits to the script make a bigger difference than any setting.
- Write for the ear: short sentences, one idea each.
- Use commas and full stops where you want pauses; a new paragraph gives a longer break.
- Spell out numbers, dates and abbreviations the way they should be said ("twenty twenty-six", "A I").
- Spell tricky names phonetically if the first read is off, then generate again.
- Pick the language in the menu when the script is not in English.
- Keep each Gemini generation under 4,000 characters and join longer parts in your editor.
Limits to know before you start
Being clear about what the tool does not do saves credits.
- Gemini 3.1 Flash TTS reads up to 4,000 characters per generation; split longer scripts.
- There is no voice cloning on this page. To create a new voice from a written description, use AI Voice Design.
- There are no speed, pitch or emotion sliders; delivery comes from the voice you pick and how the script is written.
- Output is a single MP3 file. Downloads require a paid plan; free accounts can play the audio in the browser.
Frequently asked questions
Is VdoBloom’s AI text to speech free?
You can try it free: every new account gets 10 credits, enough for one voiceover of up to 1,000 characters on Gemini 3.1 Flash TTS or xAI TTS (6 credits). Free accounts can play the result in the browser. Downloading the MP3 requires a paid plan, starting with the Lite pack of 300 credits for $19.50 one-time.
What is the best AI voice generator for voiceovers?
It depends on the script. On VdoBloom, Gemini 3.1 Flash TTS gives you 30 voices and suits longer narration and multilingual scripts, while xAI TTS has six expressive voices that work well for short hooks and ads. Both cost 6 credits per 1,000 characters, so generating the same line with a few voices is the quickest way to choose.
How many voices and languages are available?
There are 36 named voices: 30 on Gemini 3.1 Flash TTS and six on xAI TTS (una, leo, eve, ara, sal, rex). The Language menu offers 24 languages, including English, Hindi, Tamil, Telugu, Bengali, Spanish, French, German, Japanese, Korean, Chinese (Mandarin) and Arabic, plus an Auto option.
How much does a voiceover cost?
Gemini and xAI cost 6 credits per started block of 1,000 characters. A 300-character hook is 6 credits, a 2,500-character explainer is 18 credits, and the Lite pack’s 300 credits cover 50 blocks. The exact cost is shown before you generate, and failed generations are refunded.
Can I download the AI voice as an MP3?
Yes. On any paid plan, the generated speech downloads as an MP3 file that works in CapCut, Premiere, DaVinci Resolve or VdoBloom’s own video tools. Free accounts can listen to the result in the browser before upgrading.
Can AI text to speech read Hindi and other Indian languages?
Yes. The Language menu for Gemini and xAI includes Hindi, Tamil, Telugu, Marathi, Bengali, Gujarati, Kannada, Malayalam, Punjabi and Urdu. Write the script in that language and select it in the menu.
How long can my text be?
Gemini 3.1 Flash TTS reads up to 4,000 characters in one generation, so split longer scripts into parts and join the MP3s in your editor. Billing is per started block of 1,000 characters, which makes several shorter runs cost the same as one long run of the same total length.
Can I clone my own voice?
Not on this page. The text to speech tool uses the built-in voices listed above. If you need a voice that does not exist in the list, AI Voice Design creates one from a written description of age, accent, tone and pace.
Can I use the AI voiceover in commercial videos?
Under VdoBloom’s terms of service, you retain ownership of the content you generate with the service. Make sure your script itself does not infringe anyone’s rights, and do not use generated speech to impersonate a real person.
What is the difference between text to speech and speech to text?
Text to speech turns written words into spoken audio. Speech to text (transcription) does the reverse and turns a recording into written text. VdoBloom offers both: this tool for voiceovers and the Audio to Text tool for transcripts.
