script to transcripe anything with whisper

transcribe

#!/bin/sh

# this script relies on a bunch of stuff
#
#   1. ffmpeg has been installed by brew
#   2. The instructions from https://blog.castopod.org/install-whisper-cpp-on-your-mac-in-5mn-and-transcribe-all-your-podcasts-for-free/
#      have been followed to install whisper.cpp and the models.  These are:
#        cd ~/co
#        git clone https://github.com/ggerganov/whisper.cpp.git
#        cd whisper.cpp
#        make
#        cd models
#        ./download-ggml-model.sh small

# Create a temporary file
tempfile="$(mktemp).wav"

# convert the file into a wav file that whisper.cpp can read and put it there
ffmpeg -i "$1" -ar 16000 $tempfile 2>/dev/null

# use whisper to transcribe it
~/co/whisper.cpp/main \
    -nt \
    -m ~/co/whisper.cpp/models/ggml-small.bin \
    -f $tempfile \
    2>/dev/null \
    | perl -e '$_ = join "", <>; s/^\s+//ms; s/\s+$//ms; print'

# Delete the temp file manually at the end of the script
rm -f $tempfile
