⚡ 簡単な評価:
- 価格: Lovo AI plans start at $24/month. TTSOpenAI runs on credits at $0.00004 each.
- 最適な用途: Lovo AI for full video content production. TTSOpenAI for fast, clean audio and API work.
- 主な違い： Lovo bundles a video editor, ai writer and ai art generator. TTSOpenAI does one job.
- 私たちのおすすめ： TTSOpenAI, rated 4.3 against Lovo’s 4.0, for cost control and voice quality.
Most people pick a voice generator for one reason.
They are tired of hiring voice actors for every small script.
Lovo AI and TTSOpenAI both solve that, but not the same way.
Lovo is a full studio. TTSOpenAI is a narrow tool that does one job well.
That single difference decides which one you should pay for.
概要
This Lovo AI vs TTSOpenAI comparison covers pricing, voice quality, and ease of use.
We also look at voice cloning, api access, and editing tools.
Both rely on ai voice generation to convert text into audio.
弊社のライター陣は、両方のプラットフォームを実際に操作して検証しました。
それらのメモは、以下の「チームが気づいたこと」のセクションに記載されています。
By the end you will know which one fits your work.
Lovo AIとは何ですか？
Lovo AI is an ai voice generator built around a workspace called Genny.
It offers over 500 natural sounding voices that speak more than 100 languages.
You type written text, pick a voice, and it returns audio files in seconds.
Lovo also bundles an online video editor, an ai writer, and an ai art generator.
The company pitches this as an “unparalleled voiceover production experience.”
Here is a walkthrough of the platform in action.
ロボAI
Over 500 advanced ai voices across 100+ languages. Voice cloning, subtitles, and a video editor sit in the same tab. Commercial rights are included.
Lovo AIの価格設定
Here is what Lovo AI costs. Three paid tiers, no annual math needed.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 基本 | $24 | Solo creators making short video clips |
| プロ | $24 | Regular ai voiceover work with cloning |
| プロ+ | $75 | Teams producing corporate training videos |
Pricing verified September 2026.
無料トライアル: Yes. Lovo advertises a 14 day trial covering up to 20 minutes of generated voices.
返金保証: Refunds are handled case by case through support, not a blanket policy.
📌 注記： Commercial rights ship with paid plans, so you can monetise a ユーチューブ video or a client ad without a separate licence.
⚠️ Pricing conflict: Lovo’s public marketing also mentions a free plan and a $4 Starter tier. Our CSV records Basic $24, Pro $24 and Pro+ $75, and we use those figures throughout. Check the live page before you pay.
Lovo AIの主な利点
Here is what makes Lovo worth a look:
- 膨大な音声ライブラリ: 500+ premium voices in over 100 languages and accents. Finding the perfect voice takes minutes, not hours.
- Emotion range: Users can convey more than 30 distinct emotions. A single narrator can sound calm, then energetic.
- 音声クローン機能： You can create custom voices that copy your own vocal traits for consistent branding.
- オールインワンスタジオ： Script tools, subtitles, background music and sound effects live in one place.
- Commercial rights: Paid users own the output and can monetise it under normal copyright law.
- Scale without quality loss: One social post or a full e-learning module, both come out the same.

- Voice cloning and 30+ emotions in one editor
- Video editor, subtitles and ai art generator included
- Commercial rights come with paid plans

TTSOpenAIとは何ですか?
TTSOpenAI is a text to speech service built on OpenAI’s audio models.
You paste written text, choose a voice, and download the result as MP3.
The platform offers OpenAI voices such as Alloy, Onyx, Nova and Shimmer.
Output is natural sounding speech with proper intonation and emphasis.
There is no video editor here. Just text in, audio out.
This walkthrough shows the workflow from log in to first file.
🏆 受賞者：TTSOpenAI
High quality narration from OpenAI’s models. Real-time synthesis, api keys, and a custom voice maker. You pay only for what you generate.
TTSOpenAIの価格
TTSOpenAI skips tiers. You buy credits and spend them.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 使った分だけ支払う | 1クレジットあたり0.00004ドル | Anyone with uneven monthly volume |
Pricing verified September 2026.
無料トライアル: A free tier lets you test voice options before you buy credits.
返金保証: None advertised. Unused credits stay on your account instead.
📌 注記： Credit billing means a quiet month costs you almost nothing. That is the opposite of a fixed subscription.
⚠️ 警告： Long audiobooks burn credits fast. Estimate a chapter first, then scale, or the bill will surprise you.
TTSOpenAIの主な利点
Here is where this service earns its 4.3 rating:
- Model choice: TTS-1 is tuned for low latency. TTS-1-HD is tuned for high quality audio.
- Instructable delivery: The gpt-4o-mini-tts model takes plain instructions on tone, pauses and pronunciation.
- Developer access: An api lets you drop speech into your own app or into voice agents.
- Streaming output: Real-time streaming keeps playback delays short for live products.
- 言語範囲: Optimised for English but usable across many other languages and accents.
- Clean files: MP3 downloads arrive with no background noise to clean up afterwards.
私たちのチームが気づいたこと
Our writer ran the same three scripts through TTSOpenAI that we used on Lovo. Here is what came back:

- Credit billing costs nothing in a slow month
- Api keys make integration into products simple
- Real-time synthesis suits live voice agents
❌ デメリット
- No video editor, subtitles or art tools
- Voice library is small next to Lovo’s
- Credit costs are hard to forecast on long projects
機能比較
Both platforms convert written text into speech. That is where the overlap ends.
Below are ten key features that decide the choice for most buyers.
| 特徴 | ロボAI | TTSOpenAI |
|---|---|---|
| 開始価格 | $24 | 1クレジットあたり0.00004ドル |
| 無料枠 | ✅ 14日間無料トライアル | ✅ |
| 音声カウント | ✅ 500以上 | ❌ Smaller set |

| ビデオエディター | ✅ | ❌ |
| Subtitles | ✅ | ❌ |
| APIアクセス | ❌ | ✅ |
| AIアバター | ❌ | ❌ |
| 最適な用途 | Video content production | Clean audio and developers |
1. 音声ライブラリと言語
Lovo AI: The Genny workspace holds more than 500 voices across 100+ languages. That breadth is the main reason people pick Lovo over smaller AI音声ジェネレーター. If you publish in Spanish, Hindi and German, the 名簿 covers all three.
TTSOpenAI: The library is deliberately small. OpenAI’s models are optimised for English but handle multiple languages. You get a tight set of professional voices instead of endless scrolling.
⚠️ 警告： A bigger catalogue is not automatically better. Half of Lovo’s roster will never suit your brand, and testing them all eats an afternoon.
2. Voice Quality and Natural Sounding Speech
Lovo AI: Lovo markets super realistic voices that are hard to separate from real human voices. In practice the best ones are excellent and the rest are merely fine. Picking well matters more here than on the other platform.
TTSOpenAI: Output is consistently professional grade. The intonation sounds natural, phrasing is smooth, and it rarely stumbles on odd sentences. Deep learning networks trained on huge sets of audio-text pairs do the heavy lifting. That is enough to create realistic narration from a single paragraph.
3. 音声クローンとカスタムボイス
Lovo AI: Cloning is a headline feature. You record samples and Lovo builds a digital copy of your own voice for consistent narration. Neural cloning of this kind can work from clips as short as sixty seconds.
TTSOpenAI: The Custom Voice Maker lets you create custom voices, though the process is more constrained. Cloning here is a supporting tool, not the centre of the product.
💡 プロのヒント: Cloning someone else’s voice needs their consent. Transparency and permission are the two measures that keep this legal and fair to voice actors.
4. Emotion, Tone and Expressiveness
Lovo AI: You pick an emotion from a menu. Over 30 are available, so one narrator can shift from gentle to urgent inside a script. It is the faster route to an engaging tone if you dislike prompt writing.
TTSOpenAI: You describe the delivery instead. The newer models respond to written direction about speed, mood and emphasis, which makes them more expressive but less predictable. 想像する telling a narrator “read this like a bedtime story” and getting it.
5. 動画編集とコンテンツ制作
Lovo AI: The online video editor is the reason many people stay. You can drop a voiceover onto footage, add background music, and edit content effortlessly without leaving the tab. For anyone making youtube videos weekly, that saves a round trip to a separate editor.
TTSOpenAI: Nothing here. You export audio and take it into your existing editor. That suits people who already own a video workflow and only need the narration track.
6. Script Tools and Creative Extras
Lovo AI: The ai writer drafts scripts so you start from professionally written content rather than a blank page. Lovo also throws in hd royalty free images through its art tool. Those royalty free images cover thumbnails and simple slides.
TTSOpenAI: Story Maker turns a short prompt into narrated audio in one pass. It is narrower than Lovo’s kit, but it removes a step for anyone producing serialised content creation work.
7. Subtitles and Accessibility
Lovo AI: Auto subtitles generate in multiple languages, which widens reach for video content. Converting written material into human speech also helps visually impaired audiences and people with speech disabilities.
TTSOpenAI: No subtitle generator. Accessibility here comes from the audio itself, the same role text to speech technology plays inside screen readers and voice assistants.
⚠️ 警告： Neither platform generates ai avatars. If you need a talking presenter on screen, both will disappoint you.
8. APIと開発者アクセス
Lovo AI: Built for people working in a browser, not people shipping code. Developers looking for deep integration will find the options limited compared with the alternative.
TTSOpenAI: Api keys are a first-class feature. Speech can be integrated into an e-learning platform, a support desk, or a home オートメーション setup. Home アシスタント, for example, already uses OpenAI’s GPT-4o Mini TTS as a speech provider with voices including Alloy, Nova and Shimmer.
9. 使いやすさとインターフェース
Lovo AI: A user friendly interface, but a busy one. A voice generator and text editor and timeline all share the screen. Newcomers to audio production manage fine, though the first session takes longer.
TTSOpenAI: An easy to use interface with almost nothing to learn. Paste, pick, generate, download. Both platforms are browser tools, so a stable internet connection is the only hard requirement.
10. 価格設定とコスト
The two products use different pricing plans entirely.
| プラン | ロボAI | TTSOpenAI |
|---|---|---|
| エントリ | 基本料金：24ドル | 従量課金制：1クレジットあたり0.00004ドル |
| 中 | プロ：24ドル | ❌ No tiers |
| トップ | Pro+：75ドル | ❌ No tiers |
Lovo AI: You pay $24 whether you make one clip or forty. That is good value at volume and poor value if your output is uneven. Pro+ at $75 is aimed at teams.
TTSOpenAI: Credits at $0.00004 each mean a light month costs pennies. The trade is unpredictability. A long audiobook can cost more than a Lovo subscription would have.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| Uneven monthly volume | TTSOpenAI | Pay only for credits used |
| 100以上の言語 | ロボAI | Far larger voice roster |
| Api access | TTSOpenAI | Built for developers |
| Video plus audio in one tab | ロボAI | Editor and subtitles included |
| Fastest first result | TTSOpenAI | 学ぶことはほとんどない |
💰 あなたの予算
Lovo costs $24 every month whether you use it or not. Credits suit anyone whose workload swings from busy to quiet.
🔌 あなたの技術スタック
If speech has to run inside a product you maintain, TTSOpenAI is the only real option here. Lovo assumes you work in its editor.
📝 コンテンツの種類
Marketing clips and high quality videos favour Lovo, since the editor and music sit alongside the voice generation. Podcasts and audiobooks favour clean audio exports.
🎓 あなたの経験レベル
Complete beginners get a result faster on TTSOpenAI. Lovo rewards the time you spend learning its advanced features.
🆓 無料トライアルとデモ
Run the same paragraph through both before paying. Listen for a young male or older female read, whichever matches your brand, and judge the customization on offer.
🛟 サポートオプション
Lovo runs a standard help desk for account and billing questions. TTSOpenAI leans on documentation, which suits technical users better.

私たちのレビューで取り上げられなかったこと
We focused on solo creators and small teams. We did not benchmark either platform at agency scale, and we did not measure how credit costs behave across a full audiobook. Enterprise contracts and custom terms sit outside this comparison. Our notes reflect the September 2026 versions, and voice technology moves quickly. OpenAI keeps releasing new audio models, so the gap may look different in a few months.

🏆 優勝者：TTSOPENAI
TTSOpenAI wins 4 of 6 categories.
最適な用途: podcasts, product narration, developer projects, and anyone with uneven output
These are not really rival products. Lovo is a studio. TTSOpenAI is an engine.
Lovo AI earns its place if your work is video first and you want script, art, music and narration under one login. Its ai generated voices cover more ground than anything OpenAI ships, and the emotion menu gets you a usable read without writing prompts.
TTSOpenAI takes the win on the two things most buyers ask about first: cost and how human the output sounds. For the moment, its voices are the more reliable pick for audience engagement on long-form audio.
