Why convert OPUS to TXT?

Opus, standardized in 2012, stores compressed audio frames in an Ogg container - there is no text content to extract by format conversion alone. Users searching for .opus to .txt typically have a voice message from WhatsApp, Telegram, or Signal that they need as written text for a record or to share where audio is inconvenient. Only speech-to-text tools can produce a .txt output.

How to convert OPUS to TXT

OpenAI Whisper OPEN-SOURCE

Install Whisper via pip install openai-whisper, then run whisper voice.opus --language en; it accepts .opus directly and writes a .txt file in the same folder.

Microsoft Word APP

Open a blank document, go to Home > Dictate > Transcribe, upload the .opus file, and Word inserts the transcribed text; if Word rejects .opus, convert to .mp3 first with VLC.

Quality & what to watch

  • .opus stores only audio frames - there is no hidden text layer; a conventional file format converter cannot produce text from it.
  • Transcription accuracy varies with audio quality, background noise, and speaker accent.
  • Word's Transcribe may not accept .opus on all versions; convert to .mp3 with VLC first if it rejects the file.

Frequently asked questions

Can Whisper produce subtitle files as well as plain text?
Yes - Whisper can output .srt and .vtt subtitle files in addition to .txt; use the --output_format option to choose, or it writes several formats at once by default.
Does the transcription include timestamps or speaker names?
Whisper can output timestamps; speaker identification requires additional tools.
What if the audio is not in English?
Whisper supports many languages; pass --language <code> when running it to improve accuracy.
