Creating subtitles with artificial intelligence is no longer a matter for specialists: today, anyone can transform audio into text with surprising precision and without the hassle of editing. If you are interested in publishing clear, accessible videos with greater reach, you have local options on your computer and cloud tools that work wonders.
In the following lines, I explain, step by step, how to generate automatic subtitles with Whisper-based desktop software and ready-to-use online services. You'll see when each method pays off, what settings to choose, export formats, and limits on the free versions., as well as practical recommendations for polishing your style, timing, and readability without complicating things.
Why AI subtitling is worth it
Automatic subtitling is not just a matter of aesthetics: Improves comprehension, increases retention, and engages audiences for longerThere's clear data to support this: many users complete more videos when they're subtitled, because they understand the content better and concentrate more easily.
There is also a huge accessibility advantage: people with hearing difficulties, those who consume content in noisy environments or those who prefer to read, appreciate being able to follow along without relying on audio. On fast-paced platforms like Instagram or TikTok, you have just a few seconds to capture attention, and well-designed subtitles can make the difference between them skipping past it or staying.
Local option: Generate subtitles with Whisper using Buzz
If you prefer to work on your computer, a powerful and free alternative is Buzz, an application that integrates Whisper, OpenAI's automatic speech recognition model trained with hundreds of thousands of hoursWhisper doesn't just transcribe words: it also punctuates the text properly and structures it into coherent sentences and paragraphs, avoiding the "dripping text" effect without pauses or meaning.
Buzz is available for Windows, macOS, and Linux, and can be downloaded from the project's releases page. The installation is typical of any programDownload the installer for your system, run it, and that's it. Although version 0.8.4 was originally mentioned, the idea is the same with recent versions; always look for the latest version in the assets section for your platform.
When you open Buzz you will see a simple and straightforward interface. The main icons cover key transcription tasks and job management:
- Microphone: Capture audio in real time from your microphone (if your equipment is not powerful, it may be just right).
- “+” button: new transcription of an audio file you have on your computer.
- Open transcript: to review the result when the process ends.
- Cancel: Stops a task in progress if you made a mistake or need to stop.
- Delete: Deletes a task from the queue that you no longer want to keep.
For your first transcription, select the “+” button and choose an audio file. Buzz supports MP3, WAV, M4A and OGG, so it covers most cases. After selecting the file, an options window opens with important model and task settings.
Whisper Settings in Buzz: Model, Tasks, and Language
In the model section you will see Whisper with several variants: tiny, small, medium, large. Small versions transcribe faster but sacrifice accuracyIf you want the best recognition, select the large option and give it time to work its magic.
Whisper allows two types of tasks: transcribing and translating. The integrated translation is designed to carry out any language to English, not the other way around. If your goal is to get subtitles in the audio's original language, choose Transcribe. As for the language, you can enable automatic detection, although sometimes it doesn't get the results right; if you know the exact language, define “Spanish”, “Catalan”, “Galician”, “Basque” or another from the list (it is extensive and includes the usual European ones and English) to ensure the best quality.
There is a very useful box called Word Level Times. When it is active, Buzz keeps fine time stamps so that the subtitles appear exactly where each piece of text should. If you only want a continuous text that isn't used as subtitles, you can disable this to save resources.
Requirements and timing: what you need to know before you start
Transcribing with large models is demanding. For comfort, a computer with 16 GB of RAM is recommended. and processors at the level of an i7 or i9 (or equivalent). A long audio can take hours, so be patient and, if possible, leave the task in the background while you do something else.
One advantage of Buzz is that you can add multiple transcripts to the queueThe app will process them one after the other. Perfect for batches of meetings, classes, or events that you want to transcribe without having to be on top of them all the time.
Export subtitles and text: supported formats
When you finish, you enter the result and you will see the segments with their times and the recognized textFrom the download button, you can export in three key formats: TXT (plain paragraph text), SRT (a subtitle standard that works with players like VLC), and VTT (very common if you're going to use the videos in office suites, for example, to embed them in PowerPoint).
Even if something doesn't quite satisfy you, SRT and VTT files are still text. Open the file in an editor and correct proper names, unusual abbreviations, or minor errors. Hassle-free. The tool does the hard work, and you just finish it off.
A note: extracting audio from a video is a different story. If your file is still an unsplit MP4, use an extraction tool first. to extract the audio and thus pass it through Buzz without complications.
On-demand and live subtitles
In addition to the classic “I upload a file and generate subtitles” process, there are scenarios where you want real-time subtitles. Live subtitling is ideal for broadcasts, webinars and events. In which you need to accompany the signal with text to expand reach and improve the viewer experience. Some online platforms offer both modes: on-demand processing and live generation; for example, Final Cut Pro will feature AI function to transcribe to subtitles.
