I don't plan to support any editing. Export the transcription and edit it in a proper text editor. ‣ Why is the app so large? The app delivers the highest quality transcription on the market for 100 different languages. Rather than asking why it's so large, the real question is how is it so small. ‣ Why is the transcription so slow? The app favors accuracy over speed. However, performance is expected to improve in the coming months. ‣ Why must I keep the iOS app open while it transcribes? iOS apps are fundamentally restricted from operating in the background for extended periods. ‣ Can I delete some of the languages to save space? This is unfortunately not possible. The model has all the languages stored together in a way that makes it impossible to remove just some languages. More FAQs on the website. ■ Technical details The app uses the Whisper medium or small model on iOS depending on available memory and the large v3 model on macOS. ■ Privacy The transcription is done locally on your device. Nothing leaves your device. ■ Support You can contact me through the feedback button in the app.

A Speech to Text app is a useful tool that enables you to convert spoken words into written text, making it easier to transcribe voice recordings. With advancements in open AI technology, such apps have become more accurate and efficient, enabling them to transcribe even whispered speech with ease. One of the main advantages of a Speech to Text app is its ability to convert audio recordings into text. This is especially useful for journalists, researchers, and anyone who needs to create written records of meetings, interviews, or other events. The app works by using an audio converter to read the audio file and convert it into text, which can then be edited and shared as needed. In addition to converting voice recordings, a Speech to Text app can also be used for dictation, allowing you to speak directly into the app and have your words transcribed in real-time. This feature can be especially useful for individuals who struggle with writing, or for those who need to create text-based documents quickly and efficiently. Overall, a Speech to Text app is a valuable tool that can save time and improve productivity, making it easier to transcribe voice recordings and create written records of important events.
