Overview

OpenAI GPT-4o Speech-to-Text transcribes a public audio or video file into plain transcript text with optional language selection and prompt guidance. Use it for single-speaker content, voice notes, short clips, or combined transcripts when speaker labels and word timing are not required.

Use cases

  • Transcribe a voice note, demo narration, or short podcast segment into editable text.
  • Use prompt guidance to improve names, product terms, acronyms, or domain-specific language.
  • Create a plain transcript for summaries, quote extraction, or follow-up drafting.

Input tips

  • Provide a public audio_url or video URL that can be downloaded without login.
  • Keep source files within the 25 MB maximum.
  • Use gpt-4o-transcribe for the default quality path or gpt-4o-mini-transcribe for faster, lower-cost drafts.
  • Leave language blank for auto-detection, or select a language when it is known.
  • Add prompt context for proper nouns, product names, acronyms, and expected terminology.

Expected output

The AI Tool returns full transcript text, optional detected or specified language code, optional audio duration, word count, and cost metadata. The output view shows the transcript with a copy action plus language, duration, and word-count details when available.

Caveats

  • This standard mode does not return speaker labels or word-level timing.
  • Use ElevenLabs Scribe when you need diarization or downloadable word timing.
  • Noisy audio, overlapping speech, accents, music, or poor source quality can reduce accuracy.
  • Prompt guidance helps with terminology but does not guarantee exact wording.
  • Review transcripts before quoting, publishing, or using them as a source of record.
