About This Tool

This tool processes audio inputs to produce synchronized subtitles. It runs speech-to-text transcription, detects speaker turns where possible, and aligns captions to timing marks for accurate playback. Outputs include SRT and VTT formats suitable for most video players.
The workflow is data-first: upload audio, select language, choose output format, and review generated timestamps.
The system supports language-specific punctuation and adjustable segment lengths to balance caption readability with timing accuracy. Optional features include speaker labeling, glossary-based terminology, multi-language pipelines, and batch processing for large libraries. Confidence scores per segment assist reviewers in prioritizing edits, while audit trails support traceability and re-exports.
Automation reduces turnaround time and improves consistency across projects, while preserving the ability to export edited captions for downstream workflows.

Frequently Asked Questions

Find Quick Answers

What formats are supported?
The tool outputs SRT and VTT subtitle files and a plain transcript. It can also provide a time-stamped JSON structure on request. Formats are designed to integrate with common video players and editors.
How is transcription accuracy addressed?
Transcription uses a neural ASR model with optional human review for high-stakes content. Confidence scoring flags uncertain segments and permits operator-informed corrections to improve results.
Can it translate subtitles into other languages?
The base tool supports transcription in multiple languages; translation to other languages is available as an optional step using external language models, with output in the target language.
How are timestamps handled and corrections saved?
Timestamps are generated during alignment and may be adjusted post-generation. Exports reflect edits; changes are saved with the exported file. Internal revisions are kept in the session unless discarded.
