How does speech to text work?
Speech to text uses AI-powered speech recognition technology. When you upload an audio file, the AI analyzes the sound waves, identifies phonemes (speech sounds), matches them to words using language models, and considers context to produce accurate text. Our tool uses OpenAI's Whisper model, trained on 680,000 hours of multilingual audio data, which enables it to understand different accents, dialects, and speaking styles.
What file formats can I transcribe?
You can transcribe most common audio and video formats including MP3, WAV, M4A, MP4, WEBM, OGG, and more. The tool automatically extracts audio from video files, so you don't need to convert them first. Maximum file size is 25MB for free users. After transcription, you can export the text as TXT, DOCX, or generate subtitle files (SRT, VTT) for videos.
Is my audio data secure?
Yes, your privacy is our priority. Audio files are processed securely and are not permanently stored on our servers. Files are automatically deleted after transcription is complete. We use industry-standard encryption for data transmission and processing. Your transcripts are only accessible to you and are never used to train AI models or shared with third parties.
