Ready to see how Revoicer and TTSOpenAI stack up feature by feature?
We’ll compare 8 key areas to help you pick the right voice ジェネレータ.
| 特徴 | TTSOpenAI | リボイス |
|---|---|---|
| 開始価格 | $0.00004/credit | 月額37ドル |
| 無料プラン | ✅ (2,000 chars) | ❌ |
| Voice Count | 6 premium voices | 80+ AI voices |
| 言語 | 複数 | 40+ |
| APIアクセス | ✅ | ❌ |
| 音声クローン | ✅ | ✅ (paid add-on) |
| 感情コントロール | Limited (SSML) | ✅ (10+ emotions) |
| Background Music | ❌ | ✅ |
| 最適な用途 | Developers & budget users | Creators needing emotions |
1. 音声品質
TTSOpenAI: The voices sound incredibly smooth and natural. OpenAI’s neural network produces speech with proper intonation and emphasis. Voices like Nova and Alloy are hard to tell apart from real humans. The quality stays consistent across different text lengths.
リボイスャー: Voice quality is good but varies by language and voice. Some voices sound very realistic while others lean robotic. The emotion feature adds depth, but the base quality doesn’t match TTSOpenAI’s neural engine. English voices perform best.
2. Voice Selection
TTSOpenAI: You get 6 premium voices: Alloy, Echo, Fable, Onyx, Nova, and Shimmer. Each has a distinct personality. Alloy is neutral and professional. Nova sounds young and energetic. The selection is small but every voice is high quality.
リボイスャー: You get 80+ AI voices across male, female, and kid categories. This is a much bigger library. You can preview each voice before choosing. The variety is great for matching different project needs.
⚠️ Warning: More voices doesn’t always mean better quality. TTSOpenAI’s 6 voices all sound premium. Some of Revoicer’s 80+ voices sound noticeably robotic.
3. 感情とトーンのコントロール
TTSOpenAI: Emotion control is limited to SSML tags and voice selection. You can adjust speed and ピッチ. The newer models support instruction-based customization for tone. But there’s no simple dropdown menu for emotions.
リボイスャー: This is where Revoicer shines. Pick from emotions like friendly, angry, cheerful, sad, and whispering. You can also adjust volume, speaking rate, and add emphasis to specific words. No coding needed.
4. Generation Speed
TTSOpenAI: Audio generates in about 1.2 seconds for short text. Real-time streaming lets you hear audio before it finishes rendering. Even longer scripts process quickly thanks to OpenAI’s server power.
リボイスャー: A complete voiceover takes about 60 seconds on average. That’s still fast compared to hiring a voice actor. But it’s much slower than TTSOpenAI’s near-instant output.
💡 Test Result: For a 500-word script, TTSOpenAI delivered audio in 3 seconds. Revoicer took 45 seconds for the same text. Speed matters when you’re producing content at scale.
5. 言語サポート
TTSOpenAI: Supports multiple languages including English, Spanish, French, Japanese, and more. The voices are tuned best for English. Other languages work well but may sound less natural on some voices.
リボイスャー: Supports 40+ languages including German, French, Dutch, Spanish, Portuguese, Italian, Arabic, and Mandarin. Multiple English accents are available: US, UK, Australian, and Irish. Better variety for global content.
6. API and Developer Tools
TTSOpenAI: Full REST API with detailed docs. SDKs available in Python, Node.js, and Swift. Developers can embed TTS into any app, チャットボット, or website. Webhook connectors and real-time streaming are supported.
リボイスャー: No API access. Revoicer is a web-only tool. You cannot integrate it into your apps or automate voiceover creation. This is a major gap for developers and SaaS 建設業者.
7. Voice Cloning
TTSOpenAI: Custom Voice Maker lets you create unique voice profiles. You only need 60 seconds of clean audio to train a voice. Great for brands that want consistent voice identity across all content.
リボイスャー: Voice cloning is available as a paid add-on ($47). Upload a short audio clip and generate speech in your cloned voice. The results are impressive for creating personalized content.
8. Pricing & Cost
Let’s compare the pricing plans side by side.
| プラン | TTSOpenAI | リボイス |
|---|---|---|
| 無料枠 | ✅ (2,000 chars) | ❌ |
| Entry Price | $0.00004/credit | 月額37ドル |
| Mid Tier | 使った分だけ支払う | $47/month (Pro) |
| Top Tier | 使った分だけ支払う | $127/month (Agency) |
TTSOpenAI: The pay-as-you-go model is much cheaper for most users. A 10,000-character project costs about $0.40. You never waste money on unused monthly allocations. The free tier lets you test everything before spending a dime.
リボイスャー: Fixed monthly pricing works better if you create voiceovers daily. The Standard plan at $37/month gives you a set character allowance. But you pay the same whether you use 100 characters or 100,000. The 60-day refund helps reduce risk.
Different Scenarios
| If You Need… | Choose | Why |
|---|---|---|
| Tight budget | TTSOpenAI | Free tier + pay per use |
| Emotional voiceovers | リボイス | 10+ built-in emotions |
| 開発者API | TTSOpenAI | Full REST API with SDKs |
| Most voice variety | リボイス | 80+ voices vs 6 |
| Fastest generation | TTSOpenAI | 1.2 seconds vs 60 seconds |
| Kid voices | リボイス | Male, female & kid options |
| Natural sound quality | TTSOpenAI | OpenAI neural engine |
💰 Your Budget
TTSOpenAI costs less for occasional users because you only pay for credits you use. Revoicer’s flat monthly fee makes more sense if you create voiceovers every single day.
🔌 Your Tech Stack
If you need to add voice to an app, chatbot, or website, TTSOpenAI is the only choice here. Revoicer has no API, so it only works through the web browser.
📝 Your Content Type

🎓 Your Experience Level
Both tools are beginner-friendly. Revoicer’s emotion dropdown is simpler than TTSOpenAI’s SSML tags. But TTSOpenAI’s basic mode requires zero learning.
🆓 Free Trials and Demos
