What is TTSOpenAI?

TTSOpenAI is a text to speech platform powered by OpenAI’s voice engine technology.

Think of it like having a professional voice actor inside your browser.

Here’s the simple version:

You type or paste your text. You pick a voice. The tool uses a text to speech model to generate audio that sounds like a real person. You can then download the speech as MP3 files for your projects.

The platform focuses on making high quality narration easy for everyone.

Unlike older TTS technology that sounds robotic, TTSOpenAI uses deep-learning neural networks. These networks are trained on huge amounts of audio. The result? Natural sounding speech with proper tone, pauses, and emotion.

OpenAI’s TTS relies on this same technology to power voice agents and speech tools across thousands of apps.

Who Created TTSOpenAI?

TTSOpenAI was built on top of OpenAI’s text to speech technology.

The platform launched in 2022 with a beta version. It started as a simple way to access OpenAI’s TTS API through an easy to use interface.

Today, TTSOpenAI has grown fast. The site gets over 200,000 monthly visits. Users come from all over the world.

The service keeps releasing new features. They added custom voices in 2023. Multilingual support came in 2024. And emotion control tags arrived in 2025.

The company focuses on making OpenAI’s voice technology available to everyone — not just developers. They’ve integrated strong security measures to keep your data safe.

Best TTSOpenAI Features

Let’s look at the key features that make TTSOpenAI stand out from the crowd.

1. Text To Voice

This is the core feature. You paste your text and pick a voice. Then TTSOpenAI does the rest.

The text to speech model converts your words into smooth audio. It handles pronunciation well. It adds natural pauses where they belong.

I used this to create voiceovers for 3 client videos. The result sounded clean and calm. My clients couldn’t tell it was AI.

You can choose from OpenAI voices like Alloy, Echo, Fable, Onyx, Nova, and Shimmer. Each has a different tone. Some sound like a young male. Others are more gentle and expressive.

2. Input Text Pro

This feature gives you more control over how TTSOpenAI reads your text.

You can adjust pronunciation for tricky words. Add pauses where you want them. Control the speed and tone of the output.

For example, if you write instructions for an e learning course, you can slow down key parts. This makes complex ideas easier to follow.

The customization options here are what make TTSOpenAI more than just a basic TTS tool. It gives you customizable pronunciation for high-quality voice clarity.

3. API Keys

Developers love this feature. You get API access to build text to speech into your own apps.

The API is simple. Send a request with your text and voice choice. Get audio back in seconds. OpenAI’s TTS API supports real-time streaming of audio to cut delays.

This integration works great for voice agents, chatbots, and interactive apps. Developers can integrate text to speech services into their apps fast. The new models are available to developers through an API for easy integration into applications.

4. Custom Voice Maker

Want a voice that’s yours alone? The Custom Voice Maker lets you create one.

Neural voice cloning allows the creation of unique voices from audio samples as brief as 60 seconds. You upload a short recording. The system learns the voice pattern. Then it can generate speech that sounds like that person.

This is huge for brands. Imagine having one consistent voice across all your content. No more hiring different actors for each project.

The custom voices feature helps you create a voice that matches your brand’s identity.

5. Story Maker

This is a fun and useful feature. The Story Maker helps you generate speech from story templates.

You pick a template. Add your text. The tool adds the right emotion and pacing. It makes your stories sound alive.

I tested this with a children’s story for a client. The energetic tone kept listeners engaged. The gentle pauses made it feel like a real person was reading.

TTS can convert articles into podcasts or generate audiobook narration as part of content creation. This feature makes that process simple.

6. High-Fidelity Neural Voices

This is where TTSOpenAI shines brightest.

The neural voices adapt to your text. They change their tone naturally. A question sounds like a question. A command sounds firm.

OpenAI’s text to speech technology generates natural sounding speech with proper intonation and emphasis. The new audio models are pretrained on special audio data to boost performance.

The latest text to speech models produce more expressive and characterful voices. You can hear the difference right away.

7. Multilingual Support

TTSOpenAI allows users to generate speech in multiple languages.

The platform supports over 40 languages with different accents. That includes Spanish, French, Japanese, Chinese, and many more.

OpenAI TTS models are best for English. But they work well in other languages too. The accents sound natural. Not forced.

This is perfect if you need to reach a global audience. You don’t need separate tools for each language. TTSOpenAI handles it all.

8. Real-Time Synthesis

Speed matters. TTSOpenAI delivers audio fast.

The TTS-1 model is built for real-time use. It has the lowest latency. That makes it perfect for chatbots and voice agents that need to respond in a moment.

OpenAI’s TTS API supports real-time streaming. This means your users hear the audio before the full file finishes. No waiting. No delays.

Developers can customize speech speed and tone in the new text to speech models. You control how fast or slow the voice speaks.

9. Customizable Settings

TTSOpenAI gives you control over every detail.

Adjust the speed from 1x to 4x. Change the model between TTS-1 and TTS-1-HD. Pick from the full range of voice options.

The new text to speech model allows developers to instruct the model on how to say certain phrases. You can add instructions that tell the voice how to pronounce names or technical terms.

TTSOpenAI offers customizable pronunciation for any word. This feature alone saves hours of editing.

TTSOpenAI Pricing

TTSOpenAI keeps pricing simple. There are no confusing monthly plans.

Free trial: Yes — you get 2,000 characters free to test voice quality.

Money-back guarantee: No formal refund policy listed.

📌 Note: Credits are based on characters. One character equals one credit. The different pricing plans make it easy for anyone to get started. Both TTSOpenAI and Listnr offer free trials for users to test their services.

Is TTSOpenAI Worth the Price?

For what you get, TTSOpenAI is a great deal. The pay-as-you-go model means you never waste money. You only pay for what you use.

Compare that to ElevenLabs at $5/month or Murf at $19/month. TTSOpenAI wins on flexibility.

You’ll save money if: You need occasional voiceovers for video or e learning projects and don’t want a monthly bill.

You might overpay if: You generate huge volumes daily. In that case, a flat-rate plan from a competitor might be cheaper. Both Listnr and TTSOpenAI can generate audiobooks, but longer projects may cost more.

My Experience with TTSOpenAI

Here’s what actually happened when I used TTSOpenAI:

The project: I needed voiceovers for 4 client projects. Two marketing videos, one e learning course, and one podcast intro.

Timeline: 60 days of daily use.

Results:

What surprised me: The Shimmer voice worked perfectly for my e learning content. It sounded calm and clear. Students said it was easy to follow. Text to speech technology can enhance user engagement in e learning platforms. That turned out to be true.

What frustrated me: I wished I could log in and see my generation history. The account dashboard is basic. Also, the free tier runs out fast if you’re testing multiple voices and long scripts.

Would I use it again? Yes. For quick voiceovers, TTSOpenAI is my go-to. Users can generate high quality voiceovers in seconds using this technology. For longer audiobook projects, I’d pair it with ElevenLabs.

Final Thoughts

Get TTSOpenAI if: You want natural OpenAI voices with a free tier and zero monthly fees.

Skip TTSOpenAI if: You need advanced editing tools or 1,000+ voice choices inside one platform.

My verdict: After 60 days, I’m impressed. TTSOpenAI does one thing and does it well — it turns text into great-sounding audio. The OpenAI text to speech service offers high quality voice output. It’s not the most feature-rich tool. But for clean, fast, affordable voiceovers, it’s hard to beat.

OpenAI’s text to speech service supports multiple premium voices. The technology keeps getting better. And with the free tier, there’s no reason not to try it.

Rating: 4.3/5
