How to transcribe a file
Open the free speech-to-text tool at https://avaloncompany.ai/tools/speech-to-text/ and add a file from your device. The free version accepts one file at a time, up to 10 minutes long.
Leave the language on Detect automatically or select it yourself. Start with Fast, then press Transcribe. Text appears as it is transcribed.
