Caveat: you did not specify if you were expecting to find an actual auto voice transcriber tool, or a basic transcriber tool.
I'd say you'll have zero luck if you're actually expecting/hoping to find true voice recognition, but if you want more standard approaches, try these:
Package: gtranscribe
Description-en: simple GTK+ tool focused on easy transcription of spoken words
gTranscribe is a simple GTK+ tool to transcribe audio files and other
sources. The playback speed can be adjusted without changing the pitch of the
voice. It supports spell checking and resuming at the last transcribed
position.

or
Package: transcriber
Description-en: transcribe speech data using an integrated editor
Transcriber enables easy transcription of recorded speech.
It is indispensable for every task that involves examination and
transcription of audio files, like transcription of recorded interviews, song
lyrics, radio shows and so on. It is also useful if you are active
in the field of speech research.
Your use case will determine if one is ok for you or not, so there's not much more you can do but just install those and give them a spin and see if they work for you.
