Play HTとは何ですか?
Play HT is an AI voice generator that turns typed text into speech.
You type, paste, or import text into an online studio.
The platform then returns audio in MP3 or WAV format.
Its library holds over 600 AI voices across many languages.
People use it for audiobooks, podcasts, and training videos.
The brand also appears online as PlayHT and Play.ht.
Here is a walkthrough of the studio in action.
🏆 勝者: プレイHT
Over 600 AI voices, voice cloning, and audio you can download today. The free plan lets you test the sound before you pay.
Play HTの料金
Play HT lists four tiers. Here is what each one covers.
| 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 | 個人クリエイターとポッドキャスター |
| 無制限 | 月額49ドル | 大容量オーディオプロジェクト |
| プレミアム | カスタム/月 | チームと 仕事 アカウント |
Pricing verified September 2026.
無料トライアル: Yes. The free plan needs no card and works as an open trial.
返金保証: Not advertised. Cancel inside your account settings before the next billing date.
📌 注記： Research from public sources says the free tier caps you near 5,000 characters and requires attribution. Paid tiers remove that credit line.
⚠️ Pricing conflict: Our data sheet lists Creator at $31.20/month. Outside research put the same tier near $39/month. We publish the sheet figure and flag the gap. Confirm on the checkout page before you pay.
⚠️ Billing warning: Trustpilot reviewers report charges after cancelling, plan changes without notice, and credit reductions. Some users cancelled their debit cards to stop it. Keep receipts and log every cancellation.
Play HTの主なメリット
Here is what the platform does well.
- 豊富な蔵書： Over 600 AI voices ship with the service. You can filter by gender, language, and use case.
- 音声クローン: Upload a sample and the tool copies that speaker’s voice. Cross language voice cloning lets your own voice speak other languages.
- Multi voice feature: Assign different voices to each line for dialog. This is how creators build engaging, multi-speaker podcasts.
- Custom pronunciations: You can save custom pronunciations for brand names and specific words. The setting sticks across future audio projects.
- Export freedom: Download high quality audio files as MP3 or WAV. Finished voice overs work for both personal and commercial use on paid tiers.
- Publishing extras: Play HT can build an RSS feed from converted articles. That feed can push to Spotify or iTunes.
- Developer access: An API, WordPress plugin, and browser extension connect it to your existing stack.

This video walks through the tools and settings.
🥈 Runner Up: ReadSpeaker
Built for accessibility, not content production. It reads your site aloud and helps you comply with WCAG 2.2 and ADA rules.
ReadSpeakerの料金プラン
There is no public price list. You contact sales for a quote.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| カスタム見積もり | Custom pricing for everyone | Schools, business, and government sites |
Pricing verified September 2026.
無料トライアル: Demos are arranged through the sales team rather than self-serve sign up.
返金保証: Refund details sit inside your contract, not on a public page.
📌 注記： Quotes usually depend on traffic, page count, and which products you launch. Ask for the following information up front: usage caps, term length, and renewal terms.
⚠️ 警告： Be aware that custom pricing makes budgeting slower. Solo creators rarely fit this model, and there is no card-and-go option.
ReadSpeakerの主な利点
Here is where this service earns its budget.
- ReadSpeakerウェブリーダー: Visitors get text read aloud on web pages with no software to install. Words are shown as highlighted text while the voice speaks.
- docReader for files: It reads online documents and personal documents inside the browser. Nothing has to be converted first.
- Personalized settings: Each listener can change reading speed, voice, and highlighting colors. Those preferences follow the account.
- Offline listening: Content downloads as MP3 files so people can listen away from a device.
- コンプライアンスに関するサポート： The suite supports WCAG 2.2 and ADA requirements for public sector and education sites.
- Automated audio updates: When a page or course changes, the audio refreshes on its own. No one has to re-record.
- ReadSpeaker TextAid: A reading, writing, and studying tool for dyslexia and language learners. It adds a personal library, word prediction, and page masking.

機能比較
Both tools convert text to speech. What they do next is where they split apart.
Here are ten areas that decide which one belongs in your workflow.
| 特徴 | HTをプレイ | リードスピーカー |
|---|---|---|
| 開始価格 | 月額0ドル | カスタム見積もり |
| 無料プラン | ✅ | ❌ |
| Text to speech capabilities | ✅ | ✅ |
| 音声クローン | ✅ | ❌ |
| Reads live web pages | ❌ | ✅ |
| Synchronized word highlighting | ❌ | ✅ |
| Downloadable MP3 files | ✅ | ✅ |
| IVRシステム向けAI音声エージェント | ✅ | ❌ |
| WCAG 2.2およびADAに対応 | ❌ | ✅ |
| 最適な用途 | Creating voice content | Making content listenable |
1. AI音声と音声品質
HTをプレイする： The catalogue runs past 600 AI voices, and you pick different voices per project. Voice inflections and pitch shift with the tone you select, which is why the output reads as humanlike voices rather than flat narration.
リードスピーカー: Deep Neural Networks generate the speech, and the 名簿 covers 200 plus voices. The goal is clear listening comprehension across a long page, not dramatic delivery.
⚠️ 警告： Some Play HT reviewers say naturalness drops on complex terms. Test your own script with real jargon before you buy.
2. 音声の複製とカスタム音声
HTをプレイする： Upload a sample and the tool clones your own voice. Cross language voice cloning then lets that clone speak other languages while keeping your native accent.
リードスピーカー: There is no self-serve cloning. Custom text-to-speech voices are built as a brand project with the ReadSpeaker team instead.
3. Speech Generation and Editing
HTをプレイする： The speech generator is an editor. You import text, split it into lines, and use the multi voice feature to stage conversations between speakers.
リードスピーカー: There is no editing timeline at all. The engine reads whatever the page or file already says, and audio refreshes automatically when that source changes.
4. Languages, Accents and Pronunciation
HTをプレイする： Multi-lingual speech covers a wide spread of languages and different accents. You can save custom pronunciations so specific words and brand names stay right in every export.
リードスピーカー: Support spans over 50 languages, and readers choose their reading language themselves. A dictionary and translation layer helps language learners follow along.
5. Web Pages and Document Reading
HTをプレイする： A WordPress plugin and browser extension let you turn written content into audio. It produces a file to embed, so nothing on the page is read live.
リードスピーカー: This is the core job. It reads live web pages, Microsoft Word online pages, PDFs, scanned notes, and images with text, and the same setup works across other websites you own.
6. Voice Agents and IVR Systems
HTをプレイする： AI voice agents handle phone menus and IVR systems with AI generated voices. The same engine feeds voice assistants and conversational assistants inside your own apps.
リードスピーカー: The Speech Cloud API can voice a チャットボット or kiosk, but call-flow logic is not part of the product. You would pair it with a separate program for that.
7. Audio Cleanup and Voice Changing
HTをプレイする： An AI voice changer swaps the speaker on existing voiceovers, which helps when you re-cut creative videos and keep the old script.
A second tool handles the noise side of audio generation.
リードスピーカー: No cleanup or voice changing tools ship here. Audio is generated fresh each time, so there is nothing to repair.
8. Accessibility and Study Tools
HTをプレイする： Accessibility is a side effect, not a feature set. You can create an audio version of an article, but readers get no highlighting or reading controls.
リードスピーカー: TextAid adds word prediction, page masking, and a reading ruler behind a user friendly interface. Students with dyslexia or visual impairments can complete assignments without asking for help.
💡 プロのヒント: Schools weighing academic integrity should note that TextAid supports reading and writing. It does not write the assignment for the 学生.
9. Integrations, Data and Deployment
HTをプレイする： API access, a WordPress plugin, and browser tools cover most developer needs. It also builds RSS links from converted articles so audio can reach ポッドキャスト アプリ。
リードスピーカー: TextAid drops into an LMS as an LTI tool, and the Speech Engine SAPI covers on-device use. Data handling and 安全 terms are settled in the contract, which matters for public sector buyers who must protect student records.
10. 価格設定とコスト
One publishes numbers. The other does not.
| プラン | HTをプレイ | リードスピーカー |
|---|---|---|
| 無料 | 月額0ドル | ❌ |
| 入場料支払い済み | Creator — $31.20/month | Custom pricing for everyone |
| 中級クラス | Unlimited — $49/month | Custom pricing for everyone |
| 仕事 | Premium — Custom/month | Custom pricing for everyone |
HTをプレイする： You can start at $0 and know your ceiling is $49/month before Premium. That predictability is the main cost advantage for solo users.
リードスピーカー: Every quote is scoped to your traffic and page count. That fits procurement teams and frustrates anyone who wants a price today.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| A price today | HTをプレイ | Public tiers, free plan |
| プロの声優によるナレーション | HTをプレイ | 600+ voices, MP3 and WAV |
| Your own cloned voice | HTをプレイ | Cross language cloning |
| Web pages read aloud | リードスピーカー | Live reading, no downloads |
| WCAG 2.2 and ADA cover | リードスピーカー | コンプライアンスを前提に設計されています |
| Support for students | リードスピーカー | TextAid study features |
💰 あなたの予算
Play HT gives you a $0 entry point and a visible ceiling. ReadSpeaker needs a sales call before you can budget anything.
🔌 あなたの技術スタック
WordPress and podcast tools connect quickly to Play HT. If you run an LMS, ReadSpeaker services plug in as an LTI tool.
🎙️ Your Output
Ask whether you need a file you own or a page that speaks. That single answer settles most of this comparison.
🎓 あなたの経験レベル
Play HT is something one person can learn in an afternoon. ReadSpeaker assumes someone will manage rollout across a site.
🆓 無料トライアルとデモ
Run your real script through the Play HT free tier and judge the sound yourself. Book a ReadSpeaker demo with a live page from your own site.
🛟 サポートオプション
This is the sharpest gap. Trustpilot reviewers describe slow or missing Play HT support, while ReadSpeaker contracts usually include a named account contact.

私たちのレビューで取り上げられなかったこと
We focused on individual creators and small teams. We did not benchmark API performance at scale or test enterprise procurement. ReadSpeaker pricing stayed unknown because quotes are private, so we could not compare cost per page. If you run a government portal or a university with thousands of users, your priorities will differ from ours.

🏆 勝者: PLAY HT
Play HT wins 4 of 7 categories.
最適な用途: podcasts, training videos, audiobooks, and IVR systems
These are not really rivals. Play HT is a production tool for people who need audio content they can publish anywhere.
ReadSpeaker is an accessibility service. It earns its keep when a site has a legal duty to be listenable, and its study features fill a real gap for schools.
Play HT takes the win on range, price clarity, and speed to first output. Just watch the billing page closely, because that is where its reviews turn negative.
