Tarifs de Speechify
Here is what Speechify cost looks like in 2026. Three tiers, one free.
| Plan | Prix | Idéal pour |
|---|---|---|
| Limité | 0 $/mois | Testing the basic version with limited features |
| Annuel | 11,58 $/mois | Daily readers who commit for a year |
| Mensuel | 29 $/mois | Short-term use without a lock-in |
Pricing verified September 2026.

Essai gratuit : Yes. New Speechify users get a 3-day trial of the paid tier.
Garantie de remboursement : Refunds are handled case by case through support, not a fixed window.
📌 Note: Speechify Limited is the free tier name, and its word cap is the main gap. The premium plan covers roughly 150,000 words per month through premium voices. Speechify pricing also shifts by country, so your checkout total may differ.
⚠️ Pricing conflict flagged: Our research notes say Speechify sells one annual package near $139/year with no monthly subscription. Our CSV lists a separate $29/month tier. We publish the CSV figures above and recommend checking the checkout page before you buy.
Principaux avantages de Speechify
Here is what makes this versatile tool worth a look:
- Speed you control: Push playback to 900 words per minute. That sits far above average reading speed for most adults, and customizable options let you fine-tune the listening experience.
- Text highlighting: Words light up in real time as they are read. Hearing and reading together improves recall, and academic research backs that up.
- Built for reading difficulties: It cuts the mental effort of decoding, so you focus on meaning instead.
- Offline listening: Save an audio file and play it with no signal. This enhances productivity by allowing users to keep working through a reading list on a flight.
- Wide language support: Over 60 languages with lifelike AI voices. Useful for language learners who study two different languages and switch to a different language mid-session.
- Flexible imports: Copy-paste, file uploads, web links, or a camera scan. You simply upload and press play.
- Study tools: On-repeat playback and note extraction help you drill one passage until it sticks.

Qu'est-ce que TTSOpenAI ?
TTSOpenAI is a browser platform that turns just text into finished audio.
It runs on OpenAI voices built with deep-learning neural networks.
Those networks trained on huge sets of paired audio and text.
The result is natural sounding speech with real intonation and emphasis.
You pick a preset such as a calm read, a gentle tone, or a young male narrator.
Then you generate the clip and download an MP3.
Playback is smooth, and the platform offers enough control to sound deliberate rather than robotic.
Imagine a product demo where the narration matches your brand instead of a stock voice.
Developers can skip the interface and call the API instead.
This walkthrough shows the workflow end to end.

🏆 Vainqueur : TTSOpenAI

| Plan | Prix | Idéal pour |
|---|---|---|
| Paiement à l'utilisation | 0,00004 $/crédit | Creators with uneven monthly volume |
Pricing verified September 2026.

Essai gratuit : Yes. A free tier lets you log in and test the service before adding credit.
Garantie de remboursement : None stated. Credits are prepaid, so buy in small amounts first.
📌 Note: Credit billing measures usage by characters processed. Short marketing clips cost pennies. A full audiobook is a different range entirely.

Principaux avantages de TTSOpenAI
OpenAI keeps releasing updated audio models, so this is a moving target. Here is where the platform earns its rating right now:
- Two model options: TTS-1 is tuned for low latency. TTS-1-HD trades speed for high quality narration.
- Directable delivery: The gpt-4o-mini text to speech model takes plain instructions about tone, pauses, and pronunciation.
- Named voice set: Alloy, Nova, Onyx, and Shimmer cover most narration jobs without extra setup. For example, Nova suits explainer videos.
- Voix personnalisées : Neural cloning can build a unique voice from a sample as short as 60 seconds.
- Developer access: An API and API keys drop the same engine into apps, e learning courses, and voice agents that respond in real time.
- Clean exports: Every clip downloads as MP3, so you can drop it straight into a video timeline.
- Broad reach: Output is tuned for English but handles many other languages and accents.

The panel below shows the generation screen from that same session.

Avantages et inconvénients de TTSOpenAI
✅ Avantages
- Voices sound more professional grade than most rivals
- You pay per credit instead of a flat monthly fee
- Custom voice maker clones a voice from a short sample
- API keys let developers wire it into their own products
- A powerful tool for teams producing audio at volume
❌ Inconvénients
- Long projects burn credits fast and get expensive
- The interface is less beginner-friendly than Listnr
- No OCR, so it cannot read printed pages
Comparaison des fonctionnalités
Both tools convert text into audio. What they do around that job is where they split.
Below are ten key features side by side, starting with a scannable summary.
| Fonctionnalité | Discourir | TTSOpenAI |
|---|---|---|
| Prix initial | 0 $/mois | 0,00004 $/crédit |
| Plan gratuit | ✅ | ✅ |
| Lecteur OCR | ✅ | ❌ |
| Clonage vocal | ✅ | ✅ |
| Accès API | ✅ | ✅ |
| Applications mobiles | ✅ | ❌ |
| Extension Chrome | ✅ | ❌ |
| MP3 Export | ✅ | ✅ |
| Idéal pour | Écouter des documents | Producing voiceovers |
1. Voice Library and Voice Options
Discourir: The Speechify library spans more than 1,000 voices across 60-plus languages. You can adjust speed and pas per voice. Free accounts get non hd voices, while paid accounts unlock the hd voices and premium voices. Those high quality voices are the human like voices most people expect, and the gap between the tiers is obvious within a sentence.

TTSOpenAI : The catalogue is smaller but tuned. Alloy, Nova, Onyx, and Shimmer handle most narration, and each one reads with proper stress and phrasing. These are natural voices rather than flat ones, and there are fewer voice options with a higher hit rate.

2. Clonage vocal et voix personnalisées
Discourir: Cloning is bundled into the wider app rather than sold as a studio product. It works, but the output is aimed at listening rather than publishing.

TTSOpenAI : Neural cloning builds custom voices from a sample as short as 60 seconds. Record a clean take with no background noise and the clone holds up across long scripts.

⚠️ Avertissement: Clone only voices you own or have written permission to use. Both platforms put that responsibility on your account.
3. Reading Printed Text and Documents
Discourir: This is the app’s ability that nothing here matches. Optical character recognition reads printed text, typed pages, and handwriting. Point your camera at physical books and the OCR reader converts the page. PDF documents and PDF files work the same way.

TTSOpenAI : No scanning at all. It takes typed or pasted input only. If your source is a paper page, you type it first.
4. Text Input and Editing
Discourir: You import text by copy-paste, file upload, or a web link. Text editing is light, since the app assumes your written text is already final.
TTSOpenAI : The Input Text Pro editor is the difference. You mark pauses, fix pronunciation, and pass plain instructions about tone. Ask for an expressive read or an energetic one and the model responds.

5. Long-Form and Story Projects
Discourir: Long documents are the point here, but the output is playback. You listen to a book rather than produce one for an audience.
TTSOpenAI : Story Maker keeps a long script consistent across chapters. That matters for audiobooks, where a shift in tone between sections is obvious to listeners.

6. Video and Dubbing
Discourir: AI Dubbing swaps the narration on a video into a different language. For a small marketing team pushing one clip into three markets, that saves a studio booking.

TTSOpenAI : No dubbing module. You generate an audio track and sync it in your own editor. More manual, more control.
7. API Access and Integration
Discourir: An API exists and is documented. It is a side door to a consumer product, not the main entrance.

TTSOpenAI : Built for this. API keys, real-time streaming, and low-latency output make it a fit for voice agents that respond mid-conversation. Home Assistant already uses the same underlying model as a speech provider.

💡 Conseil de pro : Additional features like streaming only matter if you build. If you want an integration with an e learning course or an internal tool, test latency before you commit. TTS-1 is the low-latency model. TTS-1-HD sounds better but takes longer.
8. Language Support and Accents
Discourir: Over 60 languages, which makes it a versatile app for language learners working across different languages. Switching mid-document takes two taps.
TTSOpenAI : Output is tuned for English first. It still handles multiple languages and a range of accents, though non-English quality varies more than the English voices do.
9. Ease of Use and Platforms
Discourir: A user friendly interface across iOS, the Android app, and a Chrome extension. Cross-platform syncing means you start on a laptop and finish on a phone. Speechify stands out for people who read on the move.
TTSOpenAI : Browser only, with an easy to use interface once you know what the controls do. There is a learning curve at the moment you first open the customization panel.
10. Tarification et coût
Two different billing models, so compare by output, not by sticker price.
| Plan | Discourir | TTSOpenAI |
|---|---|---|
| Gratuit | Limité : 0 $/mois | Niveau gratuit |
| Entrée payante | Annuel : 11,58 $/mois | Paiement à l'utilisation : 0,00004 $/crédit |
| Rolling paid | Mensuel : 29 $/mois | ❌ No monthly subscription |
Discourir: Flat access. Speechify premium runs $11.58 a month on the annual commitment or $29 month to month. Premium subscription plans cover roughly 150,000 words monthly and add advanced features, so heavy readers get predictable costs. Speechify offers no cheaper middle tier, which is the main gap.
TTSOpenAI : Usage billing. A month with no projects costs nothing. A month of audiobook work costs more than any Speechify tier. Your volume decides which is cheaper.
Différents scénarios
| Si vous avez besoin | Choisir | Pourquoi |
|---|---|---|
| To read scanned pages | Discourir | Only one with OCR |
| Client voiceovers | TTSOpenAI | Cleaner exports, per-use billing |
| Occasional projects | TTSOpenAI | No monthly fee to waste |
| Daily study reading | Discourir | Mobile apps and syncing |
| Intégration pour développeurs | TTSOpenAI | API built for production |
| Support for dyslexia | Discourir | Highlighting plus speed control |
💰 Votre budget
A flat $11.58 a month beats credits once you listen daily. Sporadic users almost always spend less on credits.
🔌 Votre pile technologique
If audio has to be integrated into software you already run, the OpenAI API is the safer bet. If you just want a reader on your devices, that question does not apply.
📝 Your Source Material
Paper textbooks, receipts, and screenshots point to Speechify. Typed scripts point the other way.
🎓 Votre niveau d'expérience
Speechify asks almost nothing of a first-timer. TTSOpenAI rewards people willing to learn what each control changes.
🆓 Essais et démos gratuits
Both offer free testing. Run the same paragraph through each and judge the voice quality with your own ears.
🛟 Options d'assistance
Speechify leans on in-app help and a knowledge base. Developer-side support is documentation-first, which suits technical accounts more than casual ones.

Ce que notre analyse n'a pas couvert
We focused on individual users and small teams. We did not measure output quality across every one of the supported languages, and we did not stress-test either API at production volume. Enterprise contracts and bulk credit rates sit outside this comparison. If you are shipping voice at scale, run your own benchmark before you sign anything.
