Read and listen
Compare timestamps, speaker turns, quality indicators and the original sound.
Choose the video. Confirm the soundtrack.
Select the video as the analysis source in the Audio wizard. The interface asks you to confirm audio extraction before you continue. Add the required reference audio or video source, choose the speaker count and review the two inputs before starting.
MP4, MOV, MKV and WebM are offered video inputs. Actual compatibility depends on the streams inside the file. A silent video cannot produce a speech transcript; a damaged or unsupported soundtrack may fail during preparation.
Use time ranges to return to the sound.
The result contains an analysis audio player and timed transcript segments. Read the time range and seek the player to listen. This audio workflow analyzes speech, speaker characteristics and signal quality rather than the objects visible in the source video.
Times refer to the submitted recording. If you trim the video before uploading, the report starts from the trimmed source, so keep a note of the offset when comparing it with an older full-length copy.
A transcript is one output, not a captioned video.
Use this page when you need to read speech from an interview, lecture or other recording. It does not promise automatic translation, subtitle file export, a caption editor or a newly rendered video with subtitles. The report is the current place to inspect the recognized words.
For format changes or a separate audio download, use Media Converter. For a readable transcript, stay in Audio Analysis and compare uncertain wording with the extracted soundtrack.
Questions about this workflow
Do I need a reference file just to transcribe?
Yes, in the current workflow. Select an analysis source and a reference source before starting. There is no separate one-file transcription mode yet. For a meaningful voice comparison, use a clean sample of the voice you want to compare.
Can I close the tab?
Keep the tab open until both uploads and submission finish. Processing then continues in the background; return to your Audio task list for progress and the report.
What are the current input limits?
Each upload is limited to 512 MiB. The analysis recording can be up to 30 minutes, and the reference must contain at least 3 seconds of detected speech. Processing, storage and quality checks also apply.
A different question. The same connected report.
Audio Analysis
Analyze speech in audio or video with transcripts, speaker segments, voice comparison, quality indicators and charts in one inspectable report.
Audio to Text
Convert recorded speech into a timestamped transcript inside Audio Analysis. Review the words alongside speaker turns and source playback.
Speaker Diarization
Group speech into numbered speaker turns and timed segments. Inspect the dialogue transcript and check automatic assignments against the recording.
Voice Comparison
Compare an analysis recording with a reference voice sample. Review matched speech windows, speaker summaries and recording quality before interpreting similarity.
Listen closer. Read with context.
Find and Listen to Audio Speaker Segments
Use speaker labels, dialogue turns, matched windows and timestamps to locate and listen to passages in an Audio Analysis report.
How to Read an Audio Analysis Report
Understand source players, quality indicators, transcripts, speaker groups, voice similarity and signal charts in the current Audio Analysis report.
What Voice Similarity Scores Mean
Understand best score, top 5 median, matched speech, speaker summaries and technical similarity labels without treating them as identity probabilities.
Audio Transcription Language Support
Check the current English, Ukrainian and Russian configuration, automatic language detection and limitations for multilingual or unclear speech.
