Feature Comparison
Now let’s go feature by feature in this Speechify review and TTSOpenAI comparison.
We’ll explore the key features that matter for both creators and daily readers.
Both tools also include advanced features that help users save time on routine work.
| Feature | Speechify | TTSOpenAI |
|---|---|---|
| Starting Price | $0 (Free) | $0 (Free) |
| Free Plan | ✅ | ✅ |
| Reads PDF Files | ✅ | ❌ |
| Custom Voices | ❌ | ✅ |
| API Access | ✅ (Premium) | ✅ |
| OCR Reader | ✅ | ❌ |
| Download Audio File | ❌ | ✅ (MP3) |
| Chrome Extension | ✅ | ❌ |
| Voice Options | 1,000+ AI voices | OpenAI premium voices |
| Best For | Reading content | Creating voiceovers |
1. Voice Quality and Natural Voices
Speechify: Speechify offers over 1,000 ai voices in different languages. The premium voices sound like human like voices with smooth tone, allowing users to read for hours without ear fatigue. The basic version uses non hd voices that sound flatter than the paid hd voices, especially with background noise from a phone speaker. Many Speechify users praise the high quality voices for daily reading. Academic research suggests that hearing and reading at the same time improves comprehension.
TTSOpenAI: TTSOpenAI uses OpenAI voices like Alloy, Onyx, and Nova for natural sounding speech. The output handles emotion, pronunciation, and pauses well. Voices respond to your tone instructions, so you can request a calm, gentle, or young male delivery. For example, you can ask for an excited tone for a product demo or a calm tone for a meditation track. According to user reviews, TTSOpenAI delivers more professional grade voiceovers compared to many competitors. The easy to use interface makes the experience smooth even for first-time creators.
2. Custom Voices and Voice Cloning
Speechify: Speechify includes voice cloning on its premium subscription plans. You can imagine your own voice reading any text aloud. The feature is useful for content creators who want a personal touch. However, voice cloning is locked behind the higher tier of Speechify Premium.
TTSOpenAI: TTSOpenAI has a custom voice maker built into the platform. You can create unique characters or branded voices for your videos. The custom voice options are part of the standard pay as you go pricing. This makes it easier to test and create without higher fees.
3. Reading Existing Content
Speechify: This is where Speechify stands out. Speechify reads PDF files, web pages, emails, and physical books. The chrome extension lets you click any article and listen instantly. The Speechify app on Android and iOS also works on uploaded PDF documents.
TTSOpenAI: TTSOpenAI is not built for reading existing content. It is built for converting text into downloadable audio. You paste just text into the editor and generate an audio file. There is no PDF reader, no web extension, and no library for saved articles.
⚠️ Warning: If you want to listen to articles or PDFs on the go, TTSOpenAI is not the right tool. It is a voice generator, not a reader app.
4. Optical Character Recognition (OCR)
Speechify: Speechify reads printed text using OCR. Open the camera, point at a textbook page, and Speechify reads the words back to you. This makes physical books accessible without retyping anything. The Speechify text to speech engine handles handwritten and typed text.
TTSOpenAI: TTSOpenAI does not include OCR. You can only convert text that you paste or import as text. There is no scanning feature for printed pages or images. Users who need to read physical content should pick another tool.
5. API Access for Developers
Speechify: Speechify offers API access for developers building accessibility tools. You can integrate the Speechify text to speech engine into your own apps. The API is mainly aimed at apps that want to read content aloud. It works well for e learning platforms and reading software.
TTSOpenAI: TTSOpenAI is built with developers in mind. The API keys feature lets you generate speech from your own apps with simple integration. Once integrated, your app can stream audio in real time. It is ideal for chatbots, voice agents, and IVR systems. Developers can log in, generate a key, and start testing in minutes.
6. Reading Speed and Listening Experience
Speechify: Speechify lets you adjust playback up to 900 words per minute. That is far above the average reading speed of around 250 words per minute. The listening experience is built around long sessions. Users can also pause, rewind, and resume across devices.
TTSOpenAI: TTSOpenAI generates an audio file rather than streaming a listening experience. You can adjust speed and pitch during the conversion step. After that, you play the audio file in any media player. This works well for finished voiceover production but not for live reading.
7. Multiple Languages and Accents
Speechify: Speechify supports over 60 languages and many accents. Language learners can listen to articles in a different language to study pronunciation. The voice options include native speakers for major languages. This makes Speechify a strong tool for multilingual readers.
TTSOpenAI: TTSOpenAI also supports multiple languages and accents through OpenAI’s models. The model is tuned for English but handles many other tongues well. You can pick a voice and language from the dropdown before generating audio. The accents sound natural for major regions, and OpenAI keeps releasing new models that expand the range of supported voices.
8. Customizable Options and Tone Control
Speechify: Speechify offers customizable options like speed, voice, and highlighting style. You can pick from over 1,000 voices in the premium plan. However, you cannot fine tune emotion or specific delivery. The customization is built around the listening experience.
TTSOpenAI: TTSOpenAI gives you deeper customization for tone and delivery. You can request a calm, expressive, or energetic read in your prompt. The platform also lets you control pronunciation and pauses. This is a powerful tool for podcast and video creators.
9. AI Dubbing and Translation Features
Speechify: Speechify includes an AI dubbing feature for video creators. You can take an existing video and dub it into a different language. This adds value beyond the standard text editing and reading flow. It works best for short clips and social videos.
TTSOpenAI: TTSOpenAI does not include built in video dubbing. It focuses on raw audio file generation. You would need to combine TTSOpenAI with a video editor to dub a clip. The trade off is more control over each line of audio.
10. Pricing & Cost
Let’s compare the pricing plans side by side. Both tools offer a free version to start.
| Plan | Speechify | TTSOpenAI |
|---|---|---|
| Free | Limited (basic voices) | Free tier (test credits) |
| Annual | $11.58/month | Pay as you go |
| Monthly | $29/month | $0.00004/credit |
| Enterprise / API | Custom (Premium API) | Pay as you go |
Speechify: Speechify uses a flat subscription model with monthly or annual billing. The annual plan saves money but locks you in for a year. There is no monthly subscription cheaper than $29. The premium subscription plans suit users who read every day.
TTSOpenAI: TTSOpenAI charges by usage with very low credit pricing. Casual users pay almost nothing for short scripts. Heavy users still keep costs reasonable thanks to the per credit model. There is no monthly subscription you have to think about. At the moment, TTSOpenAI offers different pricing plans to fit casual and heavy use cases.

What Our Review Didn’t Cover
This comparison focused on individual creators and daily readers. We did not test enterprise SSO or bulk licensing for either product. Long-term audio quality drift across very large books was not measured. If you plan to generate hundreds of hours of audio per month, your usage may differ from what we observed in shorter projects.
