There are several options available for transcribing audio files for free. One way is to use a tool such as Kapwing, which allows you to upload an audio file and convert it to text using AI technology. Another option is to use Microsoft Word, which has a built-in feature that allows you to record audio and transcribe it. Additionally, there are free online tools such as Flixier and Google Docs that allow you to transcribe audio files by uploading them and using the built-in voice typing feature. It's also possible to transcribe audio files manually by listening to the audio and typing out the words. This method may be time-consuming, but it allows for greater accuracy and control over the transcription process.
