flac speech to text: transcription with timestamps and features
Automatic speech transcription
OpenAI Whisper recognizes dialogue and returns word-level timestamps used to build synchronized subtitle cues.
Local audio extraction
The browser extracts and compresses the audio track locally before sending transcription chunks, so video frames remain on your device.
Readable SRT segmentation
Words are grouped around punctuation, pauses, cue duration, and line length rather than fixed intervals, producing human readable cues.
Editable SRT preview
Review and edit sequence numbers, timestamps, cue text, and line breaks in the SubRip preview before downloading the file.
Long recording support
Long media is split into ten minute audio chunks, transcribed in order, and merged back into one continuous subtitle timeline.
Multiple spoken languages
Use automatic language detection or select the spoken language before generating subtitles for accurate transcription across languages.

How do I convert FLAC to SRT?
Upload the FLAC file, choose automatic language detection or a specific spoken language, start transcription, then review and download the SRT preview.
Does the SRT include timestamps?
Yes. OpenAI Whisper returns word-level timestamps, and SubTran converts those into numbered SubRip cues with start and end times.

What happens with long recordings?
The browser splits audio into ten minute chunks, transcribes them in sequence, and offsets timestamps so the output is a single continuous SRT file.
Can I also download TXT or VTT?
Yes. The same result can be previewed, edited, and downloaded as TXT, SRT, or WebVTT for different publishing and editing workflows.
