You're looking for an app that combines text-to-speech (TTS) with a synchronized reading experience. There are several types of apps that do this well, depending on what you're reading:
- Speechify — Imports web articles, PDFs, documents, and more, then reads them aloud while highlighting the text. It offers multiple voices and adjustable playback speed.
- NaturalReader — Reads web pages, PDFs, and documents with text highlighting. It's available on the web and mobile devices.
- Microsoft Edge Read Aloud — Built into the Edge browser. It can read many web articles aloud while highlighting the current sentence or word, making it useful for language learning.
- Apple Books — For supported books and documents, you can use iOS accessibility features such as Spoken Content to have text read aloud.
- Google Play Books — Some ebooks support Read Aloud, and Android's accessibility features can also read text while you follow along.
- ReadEra — An Android ebook reader that works well with Android's built-in text-to-speech engine for EPUBs, PDFs, and other document formats.
If your goal is language learning specifically, you might also like:
- LingQ — Lets you import articles, read while listening, save vocabulary, and review words you've learned.
- Beelinguapp — Shows your target language alongside your native language while audio plays, making it easier to follow along.
For most learners, the best experience is one that offers:
- Natural-sounding AI voices.
- Adjustable playback speed (for slower listening at first).
- Word or sentence highlighting as the audio progresses.
- Easy importing of web articles or PDFs.
- Built-in dictionary or translation features.
If you tell me your target language (for example, Spanish, Japanese, German, or Mandarin) and whether you're using iPhone, Android, Windows, or Mac, I can recommend the options that tend to work best for that combination.
