1. AI Voices Quality
スピーチファイ： This is where Speechify stands above most competitors. The speechify library offers 1,000+ AI voices across multiple languages. Voices sound natural and human like, with adjustable pitch and customizable options for different language accents.
ポッドキャスト: Podcastle includes Revoice for ai generated voices. It converts a script into spoken audio for podcast intros. The vibrant AI voices are decent, but the selection is smaller than Speechify’s lineup.
💡 テスト結果： Speechify offers more natural sounding voices in our side-by-side test. Podcastle’s TTS is better suited for short podcast intros than long form reading.
2. Audio And Video Recording
スピーチファイ： Speechify has no recording features. You cannot record audio or capture your own voice. It only plays text back to you. This makes it a listening-only tool.
ポッドキャスト: This is Podcastle’s main strength. You can capture up to 4K video recording and 48kHz lossless wav audio. Each guest gets a separate audio track, recorded locally. Internet hiccups won’t ruin the session.
3. Recording Editing Tools
スピーチファイ： No text editing or audio editing tools exist in Speechify. You can only adjust voice options and reading speed. There’s no way to trim, merge, or process audio files.
ポッドキャスト: Podcastle has a full multi-track video editor and audio editor. The drag-and-drop interface includes trimming, fade effects, and auto leveling. It’s beginner-friendly compared to other platforms like Audacity.
4. AI Powered Audio Enhancement
スピーチファイ： Speechify doesn’t process existing audio. It generates speech from written text using AI technology, but no tools clean up audio file recordings you already have.
ポッドキャスト: Magic Dust is Podcastle’s standout AI tool. One click removes background noise, balances levels, and adds a professional studio touch. It’s improving sound quality for the entire podcast at once.
5. Optical Character Recognition (OCR)
スピーチファイ： Speechify has a built-in OCR reader. Simply upload a photo or scan physical books with your phone. Speechify reads printed text aloud in seconds. This feature alone makes it a valuable tool for students.
ポッドキャスト: Podcastle does not include OCR. It’s focused on podcasting, not document scanning. To use any TTS, you’d need to import text by typing or pasting it manually.
6. クロスプラットフォーム対応
スピーチファイ： Available on iOS, the Android app, Chrome extension, Safari, Mac, and Edge. Reading progress syncs across devices. Install Speechify today on any device to start the listening experience instantly.
ポッドキャスト: Mainly a web based platform that runs in any browser. A mobile app exists, but the full editing process is best on desktop. No browser extension is available.
7. Podcast Publishing & Hosting
スピーチファイ： Speechify cannot publish content or host shows. It’s a powerful tool for content consumption, not creation. You can listen to podcasts but can’t create or distribute them.
ポッドキャスト: A built-in Hosting Hub lets you publish to Apple Podcasts, Spotify, and Google. Get an RSS feed, download analytics, and listener データ. It also imports existing shows from other platforms.
8. AI音声クローン
スピーチファイ： Speechify offers AI voice cloning through Speechify Studio. Train a custom voice model from your own voice and use it to convert text. This is a separate subscription from the main Speechify app.
ポッドキャスト: Podcastle also supports voice cloning on higher-tier plans. Create an AI version of your voice for text-based episodes, giving consistent branding across every podcast episode.
9. コラボレーションとチーム機能
スピーチファイ： Speechify is built for individual use. Enterprise plans exist for 学校 and businesses, but no real-time collaboration. You listen and learn on your own.
ポッドキャスト: The Teams plan includes shared workspaces with role-based permissions. Multiple creators can work on the same project. Real-time editing keeps everyone in sync.
10. 価格設定とコスト
Let’s compare the pricing plans for both apps side by side.
| 計画レベル | スピーチファイ | ポッドキャスト |
|---|---|---|
| 無料 | 月額0ドル（制限あり） | 月額0ドル（3時間録音） |
| 入場料支払い済み | 月額11.58ドル（年間契約） | 月額11.99ドル（必須プラン） |
| 中級 | $29/month (Monthly subscription) | 月額23.99ドル（プロプラン） |
| トップティア | エンタープライズ（カスタム） | 月額39.99ドル（ビジネスプラン） |
スピーチファイ： The annual plan at $11.58/month is competitive for premium voices. But the monthly subscription at $29 is expensive. The free version is limited. You’re paying for voice quality and the OCR reader.
ポッドキャスト: More transparent pricing with four clear tiers. Essential at $11.99/month gives solid value for solo creators. Business at $39.99 adds team features. Annual billing saves up to 40%.
