Question 1

What is Perso AI Speech to Text, and how does it differ from basic transcription tools?

Accepted Answer

Perso AI Speech to Text converts video and audio files into accurate, speaker-separated scripts in 99+ languages. Unlike basic transcription tools, it automatically detects every speaker, lets you reassign any segment to a different detected speaker, and exports editable SRT, VTT, XLSX, and JSON files for subtitling, archiving, or content workflows.

Question 2

How does Perso AI charge for Speech to Text usage?

Accepted Answer

Perso AI deducts 1 credit per minute of media length for Speech to Text and Voice Separation — the same rate as AI Dubbing. Only Lip Dubbing uses 3× credits. There is no per-feature usage cap, so you can freely allocate credits across Speech to Text, Voice Separation, and Dubbing based on your workflow needs.

Question 3

Is Perso AI Speech to Text available on the free plan?

Accepted Answer

Yes. Speech to Text is fully available on the Perso AI free plan within the included 1 minute of free credit. This lets you transcribe a short clip, verify speaker diarization accuracy, and test SRT or VTT export quality before upgrading to a paid plan for longer media.

Question 4

Does Speech to Text support Low Speed mode for higher accuracy?

Accepted Answer

No. Low Speed mode is not supported for Speech to Text or Voice Separation. It is only available for AI Dubbing and Lip Dubbing, where translation quality benefits from slower, more refined processing. Speech to Text runs on a fast, high-accuracy pipeline optimized for transcription rather than translation.

Question 5

Can I set a target language for Speech to Text output?

Accepted Answer

No. Speech to Text transcribes speech in the same language it is spoken — it is not a translation feature, so there is no target language setting. If you need to translate and re-voice your video into another language, use Perso AI Dubbing, which handles transcription, translation, and voice synthesis in one workflow.

Question 6

How does speaker diarization work in Perso AI?

Accepted Answer

Perso AI automatically detects every speaker present in the original audio or video and assigns a speaker label to each segment. You can then reassign any segment to a different detected speaker, and the updated labels are reflected in every exported file (SRT, VTT, XLSX, JSON), keeping subtitles consistent across downstream workflows.

Question 7

Which export formats does Perso AI Speech to Text support?

Accepted Answer

Perso AI Speech to Text exports four formats: SRT and VTT for subtitles and video players, XLSX for editorial review or translation workflows, and JSON for developer integrations and automation. Every format includes speaker labels, timestamps, and any edits you make in the web editor.

Question 8

How many languages does Perso AI Speech to Text support?

Accepted Answer

Perso AI Speech to Text automatically detects and transcribes 99+ languages, including English, Korean, Japanese, Spanish, German, French, Portuguese, and Russian. Language detection is automatic, so you can upload multilingual content without pre-selecting a source language.

Question 9

Can I edit the transcribed text before exporting?

Accepted Answer

Yes. You can edit any transcribed line directly inside the Perso AI web editor, fix misrecognized words, and refine punctuation. Your edits sync automatically to SRT, VTT, XLSX, and JSON exports, so you never have to manually reconcile subtitle files after correction.

Question 10

Is Perso AI Speech to Text suitable for meetings, interviews, and YouTube videos?

Accepted Answer

Yes. Perso AI Speech to Text is optimized for multi-speaker media such as team meetings, podcast interviews, webinars, and long-form YouTube videos. Automatic speaker diarization, timestamp accuracy, and direct SRT/VTT export make it a drop-in replacement for manual transcription workflows in content and research teams.
