Discover WhisperUI, a powerful Speech to Text service using OpenAI's Whisper. Learn how to use it for transcription, subtitles, and linguistic analysis, and see how it stacks up against other transcription tools in 2025.

WhisperUI is a Speech to Text service that runs on OpenAI’s Automatic Speech Recognition (ASR) system, known as Whisper. It is a handy tool that lets you turn audio files into either plain text or SRT subtitle files. This is super useful if you’re involved in transcription services, need to create subtitles for videos, or are doing any kind of linguistic analysis. WhisperUI plays nice with a bunch of different audio file types, including MP3, MP4, MPEG, MPGA, M4A, WAV, and WEBM. Just keep in mind there’s a 25MB limit for file size. What’s really neat is that it can transcribe speech in many languages and even translate those languages into English. The reason WhisperUI is so good at handling different accents and background noise is because it’s been trained on a really extensive dataset. To use WhisperUI, you’ll need an active OpenAI API Key. You’ll be charged based on the number of tokens your usage consumes, especially for the more advanced features offered through premium services.
When you opt for WhisperUI’s premium features, you unlock some great capabilities. You can upload multiple files at once, upload as many files as you need each day without limits, and easily convert your audio files into SRT format. The way OpenAI’s Whisper ASR system works within WhisperUI is pretty straightforward: you upload your audio files to the web app, and the system then transcribes the spoken words into text or SRT files. Plus, if you’re a premium user, you can also generate subtitles and use WhisperUI for detailed linguistic analysis. OpenAI handles all the billing for WhisperUI services, so your costs are tied to the tokens you use via your OpenAI API Key.
