KreadoAI AI Speech to Text is an online transcription tool that converts uploaded audio files and MP4 videos into editable text. It automatically detects the spoken language, provides a Chinese translation, and allows users to copy transcripts or export timestamped SRT subtitles. If you want to turn a script into a voiceover, use Text to Speech instead.
