Most buyers judge a voice ジェネレータ by counting voices.
That number tells you less than you think.
Play HT ships an extensive library of over 600 ai voices.
TTSOpenAI ships a short list of openai voices instead.
One is a studio for big audio projects.
The other is a fast tool that turns just text into sound.

Play HTとは何ですか?
Play HT is an ai voice generator for turning written content into speech.
You type, paste, or import text into its online studio.
It returns natural sounding ai voices in a few seconds.
People use it for audiobooks, podcasts, training videos, and e learning.
Voice cloning also lets you build a copy of your own voice.

Here is a walkthrough of the studio before we get into numbers.

HTをプレイ
Over 600 voices, voice cloning, and an audio cleaner in one site. Built for creators who ship a lot of voice content.
Play HTの料金
Play HT sells four tiers. Here is the current lineup.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 無料 | 月額0ドル | Testing voices before you commit |
| クリエイター | 月額31.20ドル | ソロポッドキャスターとビデオクリエイター |
| 無制限 | 月額49ドル | Heavy audio generation every week |
| プレミアム | カスタム/月 | 仕事 teams and high volume |
Pricing verified September 2026.

無料トライアル: The free tier acts as the trial. No card is needed to start.
返金保証: No published refund window. Cancel before renewal to avoid the next charge.
📌 注記: The free plan caps you at roughly 5,000 characters and asks for attribution. That is enough to judge voice quality, not to finish a book.
⚠️ Price conflict: Our source data lists Creator at $31.20/month, while some public write-ups quote around $39/month for the same plan. We publish the $31.20 figure and flag the gap. Check the checkout page before you pay.
⚠️ 警告: Trustpilot reviewers report charges after cancelling, plan changes without notice, and credits cut mid-cycle. Some describe it as a scam. Pay with a card you can freeze.
Play HTの主なメリット
Here is what makes Play HT worth a look:
- Huge voice choice: Over 600 ai generated voices sit in one picker. You can filter by gender, age, and native accent.
- 音声クローン: Upload a sample and the tool rebuilds that speaker’s voice. Cross language voice cloning carries it into other languages.
- Multi voice feature: Two or more speakers can trade lines in one file. That suits podcasts and dialogue scenes.
- Voice agents: The same voices power ivr systems and conversational assistants that respond to callers.
- Publishing tools: It can spin an RSS feed from converted articles for Spotify or iTunes.
- 幅広い統合: A WordPress plugin, browser extensions, and api access cover most workflows.

🏆 受賞者:TTSOpenAI
Clean OpenAI voices with no monthly lock-in. Best pick if you need high quality narration a few times a month.
TTSOpenAIの価格
The two tools use different pricing plans. TTSOpenAI measures usage in credits.
| 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 who wants no monthly bill |
Pricing verified September 2026.

無料トライアル: Yes. A free tier lets you test voice quality before you log in and top up.

📌 注記: Credit pricing scales with characters. Short marketing clips cost pennies, while a full audiobook can cost more than a monthly plan elsewhere.

These are the key features that pull people in:
- Natural voices: Output carries proper stress and emphasis. Reviewers call it more professional grade than many rivals.
- カスタム音声: A Custom Voice Maker lets you shape tone and delivery instead of taking presets as they are.
- Fine control: Newer OpenAI models accept instructions on speed, pitch, pauses, and emotion for a calm or energetic read.
- Language coverage: The models are tuned for English but handle multiple languages.
- Developer access: API keys let developers wire speech into apps, voice assistants, and internal data tools.
- ストーリーメーカー: A guided mode turns longer written pieces into narrated audio content without extra setup.

機能比較
Here is the short version before we go feature by feature. The table below covers the ten points that decide most purchases.
| 特徴 | HTをプレイ | TTSOpenAI |
|---|---|---|
| 開始価格 | $0/month, paid from $31.20 | 1クレジットあたり0.00004ドル |
| 無料プラン | ✅ | ✅ |
| 音声カウント | 600+ | Short curated list |
| 音声クローン | ✅ | ❌ |
| カスタム発音 | ✅ | ✅ |
| Voice Agents / IVR | ✅ | ❌ |
| オーディオクリーナー | ✅ | ❌ |
| APIアクセス | ✅ | ✅ |
| エクスポート形式 | MP3, WAV | MP3 |
| 最適な用途 | Cloning and high volume | Fast, clean narration |
1. Voice Library and Voice Options
HTをプレイする: The catalogue holds more than 600 ai generated voices. You can audition different voices side by side and shortlist the ones that fit your brand. Scale like that helps when one script needs several characters.

TTSOpenAI: The list is short on purpose. Each preset is polished, and the voices capable of long reads hold their tone from start to finish. You trade choice for consistency.

2. 音声の複製とカスタム音声
HTをプレイする: Upload a short clip and the system rebuilds that speaker’s voice. Cross language voice cloning then carries your own voice into other languages. The ai voice changer can also swap an existing recording to a new speaker.

TTSOpenAI: There is no sample-based cloning here. The Custom Voice Maker instead lets you build custom voices by shaping delivery on top of a preset. Good for a house style, not for copying a real person.

⚠️ 警告: Cloning someone else needs written permission. Rules on synthetic voices differ by country, so check yours before you publish.
3. 言語とアクセント
HTをプレイする: Multi-lingual speech covers dozens of languages with different accents in each. You can keep one narrator across a whole course and still hit a native accent per region.

TTSOpenAI: The models are tuned for English yet still speak multiple languages. Accents outside English are fewer, so regional work may sound generic.
4. Pronunciation and Speech Styles
HTをプレイする: You can save custom pronunciations for brand names and jargon. Fix specific words once and every later job uses them. Speech styles and pitch controls shape the read.

TTSOpenAI: Newer OpenAI audio models take plain instructions about delivery. Ask for a gentle, smooth read or a more expressive one and the voice inflections shift. For example, request a slower pace and the delivery stretches out. Customization goes past a simple pitch slider, and custom pronunciations keep technical terms clear.

5. Voice Agents and IVR Systems
HTをプレイする: Voice agents can hold live conversations and respond to callers. Teams use them in ivr systems and support lines. That is a whole product line TTSOpenAI does not match.

TTSOpenAI: ありません エージェントビルダー. Developers can still feed the api into their own voice assistants and チャットボット, but the wiring is on you.
6. Audio Cleanup and Voice Overs
HTをプレイする: An audio cleaner strips hiss and room noise from existing voiceovers. Pair it with the voice changer and you can rescue old recordings instead of booking a new session.

TTSOpenAI: Cleanup is not part of the platform. It makes new professional voiceovers well, but you will edit them in another program.
7. Long-Form Audio and Publishing
HTをプレイする: Batch jobs convert text at volume, and an RSS feed can push finished articles to Spotify or iTunes. 想像する turning a blog archive into podcasts without touching a mic. You can create a full course narration in one sitting.
TTSOpenAI: Story Maker handles chapters and articles for high quality narration. There is no feed publishing, so you upload the audio yourself.

8. APIアクセスと統合
HTをプレイする: A WordPress plugin, browser extensions, and an api cover most stacks. Publishers get audio generation inside the editor they already use.
TTSOpenAI: API keys are the main hook. Speech can be integrated into various applications, from e learning portals to internal data tools. Real-time synthesis keeps delays short.

9. 使いやすさ
HTをプレイする: More power means more menus. Voice hunting, cloning, and cleanup each sit in their own area, so the first hour is spent learning the site rather than shipping.
TTSOpenAI: Log in, paste, generate, download. The easy to use interface gets a beginner to a usable file in about a moment, which is why it wins this round.
10. 価格設定とコスト
The billing models barely 似ている each other. One is a subscription, the other a meter.
| プラン | HTをプレイ | TTSOpenAI |
|---|---|---|
| 無料 | 月額0ドル | 無料プラン |
| 入場料支払い済み | クリエイター:月額31.20ドル | 従量課金制:1クレジットあたり0.00004ドル |
| 中級クラス | 無制限プラン:月額49ドル | ❌ |
| カスタム | プレミアム:カスタム/月額 | ❌ |
HTをプレイする: At $31.20/month the Creator plan only pays off if you publish often. Unlimited at $49/month suits weekly output. Light users overpay.
TTSOpenAI: Credits at $0.00004 each mean a quiet month costs almost nothing. The maths flips on book-length work, where a flat plan wins.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| Occasional voice overs | TTSOpenAI | No monthly bill |
| 音声クローン | HTをプレイ | Clones from a sample |
| Weekly podcasts | HTをプレイ | Batch jobs and RSS |
| Fast, clean narration | TTSOpenAI | Fewer steps, steady quality |
| Phone systems | HTをプレイ | Voice agents built in |
| 初心者向けのセットアップ | TTSOpenAI | 学習曲線が短い |
💰 あなたの予算
Credits suit uneven months, since you pay only when you generate audio. A subscription wins once output is steady.
🔌 あなたの技術スタック
WordPress publishers get more from Play HT’s plugin. Teams building their own product usually prefer a plain api.
🎬 コンテンツの種類
Training videos and creative videos with several characters lean toward the bigger library. Single-narrator explainers do not.
🎓 あなたの経験レベル
A first-timer will finish a job faster on TTSOpenAI. Play HT rewards people who enjoy tuning every knob.
🆓 無料トライアルとデモ
Both let you test before paying. Run your hardest paragraph through each and compare the sound.
🛟 サポートオプション
Support is Play HT’s weak spot, with slow replies reported by reviewers. Budget for self-service either way.

私たちのレビューで取り上げられなかったこと
We looked at solo creators and small teams, not enterprise rollouts. We did not benchmark latency under load or check every language pair. Voice agent deployments and custom contracts sit outside this piece. Features move fast in this space, and OpenAI keeps releasing new audio models, so treat this as a September 2026 snapshot.

🏆 優勝者:TTSOPENAI
TTSOpenAI wins 4 of 7 categories.
最適な用途: narration, marketing clips, e learning audio, and developer projects
These two products are not really chasing the same buyer. TTSOpenAI sells clean output with almost no setup and no monthly commitment.
Play HT sells range. Cloning, voice agents, cleanup, and 600 voices make it the stronger studio for anyone producing voice work at scale.
The billing complaints are the reason it does not take the top spot here. If you need cloning, go in with a card you can freeze.
For everyone else, TTSOpenAI gets a usable file out the door faster and cheaper.
