STT & Subtitle Generator FAQ
Everything you need to know about generating VTT and SRT subtitles with Speechyou's STT transcription. Have more questions? Contact our support team.
What is STT transcription and how does it create subtitles?
STT (Speech-to-Text) transcription uses AI to convert spoken audio into written text. Speechyou's STT engine analyzes your audio, identifies speech patterns, and generates accurate text with precise timestamps. These timestamps allow us to create perfectly synchronized subtitles in VTT, SRT, and other caption formats.
What's the difference between VTT and SRT subtitle formats?
VTT (WebVTT) is designed for HTML5 video players and web browsers, supporting advanced styling like colors, fonts, and positioning. SRT (SubRip) is the most universally compatible format, working with YouTube, video editors like Premiere Pro and Final Cut, and most media players. Speechyou exports both formats with a single click.
How accurate is the AI subtitle generation?
Speechyou achieves over 95% accuracy for clear audio in supported languages. Our AI models — Whisper and our proprietary MultiLingual Pro — excel at handling accents, technical terminology, and multiple speakers. For professional-grade subtitles, we recommend reviewing and making minor edits using our built-in editor.
Can I generate subtitles in multiple languages?
Yes! Speechyou supports STT transcription in 1,700+ languages. You can also translate your subtitles to 1,700 languages with one click. This means you can upload an English video and generate Spanish, French, German, Chinese, or Japanese subtitles automatically.
How do I add the subtitles to my YouTube videos?
Simply download your subtitles as an SRT file from Speechyou, then upload it to YouTube Studio under your video's 'Subtitles' section. YouTube will automatically sync the captions with your video. The process takes less than a minute.
What video and audio formats are supported?
Speechyou supports all major formats including MP4, MOV, AVI, MKV, WebM for video, and MP3, WAV, AAC, FLAC, OGG for audio. Try Speechyou free for 3 days to explore file transcription. We automatically extract audio from video files for transcription.
Can I edit the subtitles before exporting?
Absolutely! Speechyou includes a built-in subtitle editor where you can correct text, adjust timing, split or merge segments, and add speaker labels. Our AI assistant can also help fix grammar, add punctuation, and improve readability.
Are the subtitles WCAG and ADA compliant?
Yes, subtitles generated by Speechyou meet WCAG 2.1 and ADA accessibility standards when used correctly. Our accurate timestamps and clean formatting ensure your captions are accessible to deaf and hard-of-hearing viewers. For full compliance, we recommend reviewing captions for accuracy.
