1. AI Voices and Voice Generation
Discourir: The voice generator is the core of the tool. It creates clear, natural AI voices for professional voiceovers. You can pick a voice, paste written text, and hear audio in a few seconds.

Sous-titres IA : Voices here serve video, not long reading. The AI Creators feature pairs generated voices with on-screen avatars. The focus is video content, so the voice rides on top of the visuals.

2. Voice Cloning and AI Twins
Discourir: Voice cloning copies your voice from a short sample. You can then read any file or document in your own voice. This is handy for a personal, branded audio library.

Sous-titres IA : AI Twins clones both your voice and your face. You record once, then generate new talking videos from a script. It is voice cloning built for video, not for reading documents.

3. Text to Speech and Audio Content
Discourir: This is where Speechify wins by a mile. It turns written content into audio content you can listen to anywhere. Choose Speechify for turning text into lifelike audio at up to 900 words per minute.

Sous-titres IA : It does not read long documents aloud. The AI Shorts feature instead spins ideas into ready-to-post video clips. Speechify focuses on audio, while Captions AI focuses on video.

💡 Résultat du test : If your goal is listening to text, Speechify is the clear pick. If your goal is making short videos, Captions AI is built for that job.
4. Video Creation and Editing
Discourir: Speechify does not specialize in visual video captioning or editing. Its focus stays on audio learning and reading. For real video creation, you would need a different tool.
Sous-titres IA : The AI Edit feature trims, cleans, and styles your footage fast. It is tailored for quick visual edits and mobile-first use. Here is how the editing flow looks in the app.

Beyond basic trims, you can fine-tune the look of each clip. Video customization tools control fonts, colors, and layout.

5. Captions, Subtitles, and Transcription
Discourir: Scan & Listen reads printed pages and PDFs out loud. Its transcription accuracy averages around 90%, and transcription is not its main focus. Speechify lacks a primary focus on transcription quality.

Sous-titres IA : This is its home turf. It transcribes speech and generates kinetic, animated captions for video. The auto-captions tool builds stylized subtitles that sync to your words.

⚠️ Avertissement: Neither tool is a dedicated transcription app. For pure accuracy, specialized tools go further. Sonix offers up to 99% accuracy, Happy Scribe supports over 120 languages, Otter.ai handles meetings and lectures, Rev.ai is HIPAA-compliant, Fireflies gives 800 minutes of free storage, and Wavel AI summarizes in any language.
6. Multiple Languages and Translation
Discourir: AI Dubbing reads your written text aloud in multiple languages. You can listen to the same file in different voices. This helps you reach a wider world without re-recording.

Sous-titres IA : Translation here is built for video. It translates spoken video into multiple languages while syncing lip movements. The result looks natural, as if you filmed it in that language.
7. AI Avatars and Talking Videos
Discourir: Il n'y a pas avatar feature. Speechify is an audio tool, so it has no on-screen face. You get voice, not video.
Sous-titres IA : L'IA Avatar generator creates avatars from text or video scripts. You type a script and get a talking video back. This is useful for ads, présentations, and faceless channels.

8. Video Polish: Eye Contact and Noise Removal
Sous-titres IA : AI Eye Contact fixes your gaze so you appear to look at the camera. It makes talking-head videos feel more engaging and natural.

A background noise remover then cleans up messy audio. This gives clips a professional sound without extra gear.

Discourir: These video polish tools have no match in Speechify. Its job is reading text, not cleaning footage. That is the clearest break between the two apps.
9. Integrations and Access
Discourir: API access lets developers add text to speech to their own apps. You also get a browser extension and mobile apps. Your library syncs across platforms.

Sous-titres IA : Access is mobile-first, with desktop options for editing. The site and apps focus on a fast, simple flow. You record, caption, and post from one place.

Sous-titres IA : The Pro plan starts at $9.99/month, the lowest entry price in this comparison. There is no free plan, only a free trial, so you pay to keep making videos.
