What is TTSOpenAI?
Status: discontinued. The ttsopenai.com domain no longer resolves. Two independent public DNS resolvers return no A and no AAAA records for ttsopenai.com, and no records at all for www.ttsopenai.com, so nothing can be served. The zone still exists on Cloudflare, but it publishes no web address. Everything below is a record of what the product was.
First, the disclosure that mattered: TTSOpenAI was not a product made by OpenAI Inc., the company behind ChatGPT, GPT-5, and DALL·E. It was an independent third-party web application that wrapped OpenAI's public text-to-speech API into a consumer-friendly interface. The brand "TTSOpenAI" described the underlying technology (OpenAI's TTS endpoint) rather than the corporate maker. The site was operated by a team called Ainnate, and the official domain ttsopenai.com issued a 301 redirect to tts.ainnate.com before it stopped resolving. We flagged this because trademark confusion around "OpenAI" branding is genuinely common, and you deserved to know whose terms of service you were agreeing to.
With that out of the way: TTSOpenAI did a useful, narrow job well. OpenAI's TTS API costs roughly $15 per million characters at the developer level, but you have to write code, manage API keys, and stitch together file delivery. TTSOpenAI handed you a textarea, a voice picker, a "Generate" button, and an MP3 download, no developer skills required. The free allowance of 2,000 characters let you evaluate quality before spending anything, and paid credits started at around $8 for 200,000 credits (1 character = 1 credit) with no monthly subscription, which put it in a different price universe from ElevenLabs (where 200,000 characters is roughly the Creator tier at $22/mo) or Murf AI ($23+/mo). None of those packs can be bought now.
The voices were the six standard OpenAI TTS voices: Alloy (neutral all-rounder), Echo (warm male), Fable (British male, story-friendly), Onyx (deep male), Nova (bright female), and Shimmer (softer female). The platform supported 40+ languages, pronunciation was handled entirely by the underlying OpenAI model, so quality on non-English content matched whatever the API itself produced. Output was downloadable MP3, and audio generated through the platform was generally suitable for commercial use as long as you respected OpenAI's underlying usage policy. Compared with first-party studios like ElevenLabs, Murf, or Play.HT, TTSOpenAI was dramatically cheaper but less expressive, the right tool for documentation read-throughs, accessibility versions of articles, language-learning audio, e-learning narration, and YouTube voice-overs where you wanted clean speech rather than dramatic performance.
TTSOpenAI Pricing (Verified July 2026)
Discontinued, historical record. TTSOpenAI is no longer sold, and the prices below can no longer be purchased. The ttsopenai.com domain no longer resolves: two independent public DNS resolvers return no A and no AAAA records for it, and none at all for www.ttsopenai.com, so there is no pricing page, no signup, and no checkout left to reach. The Cloudflare zone is still registered but publishes no web address. TTSOpenAI used a credit-based, pay-as-you-go model rather than monthly subscriptions. 1 character = 1 credit, so a 2,000-word blog post (~13,000 characters) consumed about 13,000 credits. There was no auto-renewal, you bought credit packs and they sat in your account until used. These were the last figures published on the official site:
| Plan | Price | Allowance | Best for |
|---|---|---|---|
| Free | $0, no credit card | 2,000 characters (one-time) | Quality testing |
| Starter Credit Pack | ~$8 | 200,000 credits (= 200K characters) | YouTube creators, hobbyists |
| Pay-as-you-go | ~$0.00004 / credit | Buy more credits any time | Variable workloads |
| Higher tiers | Volume packs (~$19+, $89+) | 2M, 10M+ credits | Course producers, agencies |
How that used to feel in practice: 200K credits at $8 covered roughly 30,000 spoken words, about 3.5 hours of audio at average reading speed. The same volume on ElevenLabs Creator costs $22/mo, and on Murf Creator about $23/mo. For users who did not need voice cloning or expressive emotional control, TTSOpenAI's price-per-minute was roughly 60-75% lower.
The 6 Voices Explained
TTSOpenAI exposes the same six voices that OpenAI ships with its tts-1 and tts-1-hd endpoints. There is no proprietary voice library, these are OpenAI's stock voices.
Neutral, gender-balanced, all-purpose. Default pick for documentation, articles, and product walkthroughs.
Warm, mid-pitch male. Friendly tone, works for tutorials and conversational explainers.
British-accented male, narrative cadence. The best pick for fiction read-throughs and storytelling content.
Deep, authoritative male. Documentary-style, ideal for serious topics, news read-throughs, ads.
Bright, energetic female. Strong default for marketing videos, social-media voice-overs, e-learning.
Softer, gentler female. Calm meditation, ASMR-style guides, audiobook narration that needs warmth.
Note: ElevenLabs offers 1,000+ pre-built voices plus instant cloning. Murf has 120+. Play.HT has 800+. If voice variety is a hard requirement, TTSOpenAI is not the right pick, but for clean, intelligible narration, six is often enough.
Supported Languages
Because pronunciation is handled by the underlying OpenAI model, TTSOpenAI supports 40+ languages with reasonable accents. The same six voices speak all languages, there is no separate "French male voice", meaning Nova reading Spanish sounds like an American speaker pronouncing Spanish. For native-quality non-English voiceovers, ElevenLabs or Murf (which train language-specific voice talent) will outperform TTSOpenAI.
Output Formats & Commercial Use
Output format: The web interface delivers downloadable MP3 files. The underlying OpenAI API supports MP3, Opus, AAC, FLAC, WAV, and PCM formats, but TTSOpenAI's consumer UI defaults to MP3, which is fine for 95% of voiceover, podcast, and YouTube use. If you need WAV or FLAC for broadcast or pro-audio editing, you'll either need to convert the MP3 (some quality loss) or call OpenAI's API directly.
Commercial use: Audio generated through TTSOpenAI is generally usable in commercial projects, ads, paid courses, monetized YouTube videos, podcast episodes, provided you also comply with OpenAI's underlying usage policy (no impersonation, no political deception, no harassment). There is no extra "commercial license" upcharge the way Murf and ElevenLabs structure it, the credits you buy include commercial rights. Always read TTSOpenAI's current terms before launching paid content, especially for political, medical, or financial use cases.
Voice attribution: The six OpenAI voices are not real people, so there are no individual voice-actor consent issues. However, you should not market the audio as "celebrity X" or otherwise mislead listeners about who is speaking.
Voice Quality vs ElevenLabs, Murf & Play.HT
Honest assessment based on side-by-side testing of identical scripts at default settings:
| Criterion | TTSOpenAI | ElevenLabs | Murf | Play.HT |
|---|---|---|---|---|
| Naturalness (English) | Good | Excellent | Very good | Excellent |
| Emotional range | Limited | Best in class | Moderate | Strong |
| Voice count | 6 | 1,000+ | 120+ | 800+ |
| Voice cloning | No | Yes (instant + pro) | Pro tier only | Yes |
| Free tier | 2K chars one-time | 10K chars/mo | 10 min/mo | 5,000 words |
| Starting paid price | $8 / 200K chars | $5/mo · 30K | $23/mo | $31.20/mo |
| Best for | Cheap batch narration | Studio-quality VO | Corporate / e-learning | Long-form podcast |
The honest summary: TTSOpenAI's voices were clean, natural, and intelligible. They were not the most expressive on the market and they did not ship with cloning, but at $8 for 200,000 characters they cost a fraction of any subscription competitor. That trade is no longer on offer, because the product is discontinued and the domain no longer resolves, so "read this article aloud" and "narrate these slides" work now goes to one of the alternatives above. If your project is "make a believable audiobook in the voice of a specific narrator," ElevenLabs is worth its price.

Best For
These were the fits while TTSOpenAI was live; it can no longer be bought. Indie YouTube creators and content marketers who need clean, neutral narration over slides, demos, or B-roll without paying $22+/mo for ElevenLabs Creator. E-learning developers and course producers generating large volumes of explainer audio where voice consistency matters more than dramatic range. Accessibility-focused publishers producing audio versions of articles, blogs, or documentation where the goal is intelligibility, not performance. Language learners and educators needing fast text-to-audio for foreign-language practice scripts. Hobbyists and indie devs who want OpenAI's TTS without writing API code or managing keys.
📋 Good to know
Historical: you visited ttsopenai.com (which redirected to tts.ainnate.com), pasted text into the box, picked one of six voices, and clicked Generate. The first 2,000 characters required no signup, and larger volumes needed an account and a credit purchase. There is no setup path today, because the domain no longer resolves.
Text you pasted was sent to TTSOpenAI's servers and forwarded to OpenAI's API. It was to be treated like any third-party processor: medical, legal, or confidential business content did not belong there unless you had reviewed the operator's terms of service.
If you need voice cloning, branded voices, or expressive emotional delivery, jump to ElevenLabs. If you need a polished editor and team collaboration, Murf AI. If you want OpenAI TTS programmatically, just call the OpenAI API directly.
Near-zero. Paste text, pick a voice, click generate. There is no project file, no editor, no advanced parameters to configure. The simplicity is the product.

Frequently Asked Questions
Is TTSOpenAI made by OpenAI?
No. TTSOpenAI was an independent third-party application that called OpenAI's text-to-speech API. It was not built, owned, or operated by OpenAI Inc. (the company behind ChatGPT, GPT-5, and DALL·E). The site was operated by a team called Ainnate, and ttsopenai.com redirected to tts.ainnate.com before the domain stopped resolving. The "OpenAI" in the product name referred to the underlying TTS API the platform used, not to corporate ownership. If you specifically want OpenAI's first-party speech features, see ChatGPT Voice Mode or call the OpenAI API directly.
Is TTSOpenAI free?
Not any more. TTSOpenAI is discontinued and the ttsopenai.com domain no longer resolves, so there is no signup left and no way to buy credits. Historically the answer was yes, with a one-time 2,000-character free allowance, no credit card required. That was roughly 3 minutes of generated audio, enough to evaluate voice quality and decide whether to buy credits. After the free allotment you switched to pay-as-you-go credits, starting at around $8 for 200,000 credits (1 character = 1 credit). There was no monthly subscription on the entry tier.
How much does TTSOpenAI cost?
These were TTSOpenAI's last published rates, and they can no longer be purchased. Free for the first 2,000 characters. Paid credits started at roughly $8 for 200,000 credits, with larger packs at higher volumes (around $19 for 2 million and $89 for 10 million, plus custom enterprise quotes). Because credits did not expire and 1 credit = 1 character, you only paid for what you actually generated. For comparison, the same 200,000-character workload would cost roughly $22/mo on ElevenLabs Creator or $23+/mo on Murf Creator.
How many voices does TTSOpenAI offer?
Six. They are the standard OpenAI TTS voices: Alloy (neutral), Echo (warm male), Fable (British male, narrative), Onyx (deep male), Nova (bright female), and Shimmer (softer female). For comparison, ElevenLabs ships 1,000+ voices plus instant cloning, Murf has 120+, and Play.HT has 800+. If voice variety is critical, TTSOpenAI is the wrong choice. If you only need clean, neutral narration, six is usually enough.
What languages does TTSOpenAI support?
Around 40+, including English, Spanish, French, German, Italian, Portuguese, Dutch, Polish, Turkish, Russian, Japanese, Korean, Mandarin, Arabic, Hindi, Vietnamese, Indonesian, Ukrainian, Czech, Swedish, Greek, Hebrew, and many more. Pronunciation comes from the underlying OpenAI model. The same six voices speak every language, so non-English audio is technically intelligible but not natively accented, for native-quality non-English voiceovers, ElevenLabs or Murf (which use language-specific voice talent) will outperform TTSOpenAI.
Can I use TTSOpenAI audio commercially?
Yes. Audio generated through TTSOpenAI can be used in commercial projects, paid courses, ads, monetized YouTube videos, podcasts, ebooks, provided you also comply with OpenAI's underlying usage policy (no impersonation of real people, no political deception, no harassment). There is no separate "commercial license" upcharge: commercial rights are included with paid credits. Always re-read the platform's current terms before launching paid work.
What output formats does TTSOpenAI support?
The web interface delivers MP3 downloads. The underlying OpenAI API technically supports MP3, Opus, AAC, FLAC, WAV, and PCM, but the consumer-facing UI defaults to MP3, which is fine for almost all voiceover, podcast, and video use cases. If you need uncompressed WAV or FLAC for broadcast or pro-audio editing, you'll need to convert the MP3 (slight quality cost) or call OpenAI's API directly.
TTSOpenAI vs ElevenLabs, which should I pick?
If your priority is the most realistic, expressive, emotionally rich voice possible, plus the ability to clone your own voice, choose ElevenLabs. TTSOpenAI is no longer an option, because the ttsopenai.com domain no longer resolves. While it was live, ElevenLabs Creator at $22/mo gave you 100,000 characters and access to 1,000+ voices and cloning, and TTSOpenAI gave you 200,000 characters for $8, six voices, and no cloning. Different products for different jobs. See our full TTSOpenAI vs ElevenLabs comparison.
TTSOpenAI vs Murf AI, which is better?
Murf AI is a polished studio with a built-in editor, 120+ voices, team collaboration, and a Creator plan at $23/mo. TTSOpenAI was a stripped-down generator with six voices and pay-as-you-go pricing, and it can no longer be picked, because the ttsopenai.com domain no longer resolves. Murf is the remaining option of the two, and it suits e-learning courses, corporate explainers, and anything that needs storyboard-style editing.
Does TTSOpenAI offer voice cloning?
No. The platform exposes only OpenAI's six stock voices. Some third-party reviews mention a "custom voice" feature on higher tiers, but that capability is inconsistent and not part of OpenAI's underlying TTS API. If voice cloning is a requirement, use ElevenLabs (instant cloning from one minute of audio), Play.HT, or Resemble AI.
Is TTSOpenAI safe to use? Will OpenAI shut it down?
The platform itself is gone: the ttsopenai.com domain no longer resolves, so nothing new can be generated there. Audio generated while it was live is still safe to use. The platform risk was always that any third-party API wrapper depends on the provider keeping the underlying API available and on its own operator (Ainnate) staying in business and maintaining its OpenAI account in good standing. There have been waves of "OpenAI"-branded third-party apps in the past that were rebranded under cease-and-desist pressure. That risk has now materialized, which is the argument for keeping your scripts in source-of-truth files outside any single platform so you can re-render them with a different tool.
What is the maximum text length per generation?
The underlying OpenAI TTS API caps single requests at 4,096 characters. The TTSOpenAI interface accepts longer pastes and chunks them automatically before stitching the audio back together. In practice this means you can paste a full 10,000-word article and receive one continuous MP3, the platform handles the splitting for you, though the credit count is the full character total.
Should I just call OpenAI's TTS API directly instead?
If you have any developer skill, yes, calling OpenAI's tts-1 endpoint directly is cheaper at the margin (around $15 per million characters versus the ~$40 per million implied by TTSOpenAI's $8/200K pack), gives you all output formats (MP3, WAV, FLAC, Opus, PCM, AAC), and avoids depending on a third-party operator. TTSOpenAI's value is purely "no code, no API key, browser-only", you're paying a small premium for convenience. For non-developers and one-off projects, that premium is reasonable; for high-volume production, talk to your engineer.
