1. Text to Speech and AI Voices
スピーチファイ: This is where Speechify truly stands out. The Speechify library offers over 1,000 ai voices across more than 60 different languages. The premium voices sound human like and natural. You can adjust speed, pitch, and accent to fit your listening experience. Premium voices include celebrity-style options that make every audio file fun.

説明: Descript includes stock ai voices for basic text to speech. But text to speech is not its main focus. The voice options are far fewer than Speechify text to speech. It works better for generating voiceovers in editing videos than for reading documents.
2. 音声および動画編集
スピーチファイ: Speechify does not offer any audio editing or video editing tools. It is a pure listening app. You cannot trim, cut, or modify audio files.
説明: Descript is a full video editor and audio editor. You edit audio by editing the transcribed text. Delete a sentence from the text editor view, and it disappears from the recording. This text-based approach makes podcast editing as easy as using a word processor. Descript features rival the entirely new capabilities once locked behind pro tools like Final Cut Pro.

3. AI音声クローニング
スピーチファイ: Speechify does not include ai voice cloning for end users. You pick from pre-made voice options in the Speechify library. There is no way to clone your own voice.
説明: Descript’s overdub voice cloning clones your own voice from a short sample. Then you can type new sentences and hear them spoken in your voice. This is perfect for fixing mistakes in just a few minutes without re-recording uploaded audio.

4. Descript Transcription
スピーチファイ: Speechify does not transcribe audio. It only handles converting text into spoken words — not the other way around. You need a separate tool for transcription work.
説明: Descript transcription automatically transcribes audio and video files with around 90% accurate transcription. It supports 22+ languages and identifies different speakers. The transcription powers its text-based editing, so every word becomes editable.

⚠️ 警告: Descript transcription can struggle with heavy accents or technical jargon. Always proofread before final editing audio.
5. Filler Word Removal and Studio Sound
スピーチファイ: This feature does not exist in Speechify. Since it reads written text aloud, there are no filler words to remove from any audio file.
説明: Filler word removal finds every “um,” “uh,” and “like” in your record audio sessions. One click removes them all. Studio Sound also strips background noise to deliver professional production quality. Your podcast or video instantly sounds polished.


6. OCRと文書スキャン
スピーチファイ: Speechify reads printed text using optical character recognition. Point your phone at a book page and the ocr reader turns it into audio instantly. This also works with handwritten notes, helping auditory learners absorb pdf documents and physical books anywhere.

説明: Descript does not include OCR or document scanning. It only works with uploaded audio and video files. The tool is built for content creators, not for reading documents.
7. Screen Recording and AI Tools
スピーチファイ: Speechify cannot do screen recording. It focuses entirely on text editing and reading text aloud. There are no production tools here.
説明: Descript has built-in screen recording that captures screen and webcam at the same time. Then you edit the recording using text-based editing. Descript also includes ai audio tools, ai eye contact, and an AI アシスタント called Underlord that finds highlights and generates B-roll.

8. Collaboration and Remote Recording
スピーチファイ: Speechify is a personal listening tool. There are no team collaboration or remote recording features. You cannot share projects with other team members.
説明: Multiple team members edit the same project at once, similar to a google doc. The Business plan adds shared brand kits, priority support, and complex interface covered training. The platform supports remote recording with up to 10 guests on the call.

9. プラットフォームおよびデバイスのサポート
スピーチファイ: Speechify works on iOS, the android app, Mac, and as a browser extension for Chrome and Edge browsers. It also supports offline listening, which makes Speechify a more portable versatile tool than a desktop app.
説明: Descript runs as a desktop app on Mac and Windows. A web-based beta version is also available. There is no mobile app. You need a computer to use Descript for editing work.
