How long can my study notes be per file?

You paste a section at a time, not a whole binder. Each generation handles a solid chunk, roughly a couple thousand words, which covers one topic or a lecture's worth of notes. For a full unit, split it by topic: paste one, download the MP3, then do the next. You end up with a small set of short files, which is actually better for revision than one giant recording you can never find your place in.

What speed should I use for studying?

Slower than you think for new material. Set it a little under normal pace the first time through dense notes so definitions and steps have room to land. Once you know the content and you're just reinforcing it, bump the speed up to review faster. Set the speed before you download, because it bakes into the MP3 and you'd have to redo the file to change it.

Is converting my notes to audio private?

Be clear-eyed here. The text you paste is sent to a server to generate the audio, so this is not an offline or on-device tool. For ordinary class notes that's a non-issue. If your notes contain something you'd never put in a document you share, leave that part out before you paste. The MP3 you download is yours, with no watermark and no account attached to it.

Will it read my abbreviations and symbols right?

Some will trip it up. Shorthand like 'w/', arrows, and heavy abbreviation get read literally or skipped. Before you paste, do a quick find-and-replace to spell out the ones that matter, so 'defn' becomes 'definition' and '=' becomes 'equals' where it counts. Preview the first paragraph and you'll catch the rest fast.

Convert Study Notes to Audio Free (Revise by Ear)

You wrote the notes. Now you want to actually get them into your head, and rereading the same page for the fifth time isn't doing it. Turning your study notes into audio lets you revise on a walk, on the bus, or while the dishes pile up, which is time you were never going to spend rereading anyway. The good news is you can do it free in about a minute, and you download a real MP3 at the end. Here's the honest version, tuned for notes specifically rather than generic text.

How to convert your study notes to audio

The flow is short:

Open your notes, wherever they live. A Google Doc, Word, Notion, OneNote, a plain text file.
Select and copy the section you want to hear. One topic at a time works best.
Open a text-to-speech tool in your browser. No install, no account.
Paste the text into the box.
Pick a voice and accent, then press play to check the first paragraph.
Set the speed, then download the MP3.

Drop the files on your phone and you've got a revision playlist. That's the whole thing. The part worth slowing down on is what you paste and how you prep it, because notes are messier than clean prose and a little cleanup makes the audio far more useful.

Clean up your notes before you paste

This is the step that separates useful revision audio from a garbled mess. Your notes are full of shorthand that reads fine with your eyes and badly out loud.

Spell out the abbreviations that carry meaning. A quick find-and-replace turns "defn" into "definition," "w/" into "with," and "vs" into "versus." Symbols are the other trap. An arrow, an equals sign, or a plus in the middle of a sentence gets read literally or dropped, so where the symbol is load-bearing, write the word. You don't need to fix everything, just the bits where a wrong read would confuse you later.

Cut the pure visual clutter too. Bullet markers, table borders, and lone page numbers add nothing when spoken. A few minutes of tidying and the audio sounds like someone reading you a clean summary instead of decoding a whiteboard.

Chunk by topic, not by page

Don't paste an entire unit as one wall of text. Split it the way you'd split it for a study session, one topic or concept per file. There's a generous cap per generation, roughly a couple thousand words, which is plenty for a single topic, but the real reason to chunk is retrieval. A three minute file called "Krebs cycle" is something you can replay on demand right before it matters. A forty minute file called "Biology" is something you'll skip.

Short, named files also make active recall easier by ear. Play a topic, pause, try to say the key points back before the audio does, then let it confirm. That call-and-response is where the learning happens, and it only works when the chunks are small enough to hold in your head.

Pick a voice that survives repetition

You're going to hear this voice a lot, so pick for endurance, not novelty. Natural neural voices sound like a person reading rather than the flat robotic readers from years ago, and there's a real choice of accent, US, UK, and Australian English, across a few voices. Preview two or three on your first paragraph and choose the one that's easiest to listen to when you're tired. A voice you find grating gets abandoned by day two, and the best revision tool is the one you keep using.

Use speed as a study tool

Speed isn't just comfort, it's part of the method. Set it a touch slow the first time through new material so definitions and steps have room to land. On later passes, when you already half know the content, push the speed up and use the file as a fast reinforcement loop. Because the speed bakes into the downloaded MP3, a good trick is to make two versions of a tough topic, one slower for learning and one faster for review, and move from one to the other as the exam gets closer.

A realistic note on what this is

Two honest caveats so you're not surprised. First, the text you paste is sent to a server to make the audio, so this isn't an offline or private tool. For normal class notes that doesn't matter. If a section is genuinely sensitive, just leave it out. Second, this reads a section at a time, not your entire semester in one automated batch. That's fine for revision, where small named files beat one endless recording anyway, but if you were hoping to convert a whole textbook into a single file untouched, that's a different, paid kind of product, and it's fair to say so.

What you get instead is quick, free, and genuinely useful: clean MP3s of your own notes, in your chosen voice and speed, with no watermark and no account, ready to revise from anywhere.
