One-Click Audio Transcription Script: Seamless Setup and Processing

This updated one-click script simplifies audio transcription like never before. It checks for and installs Homebrew, Python, and FFmpeg automatically, ensures the necessary Python packages are installed, and processes MP4 or MP3 files into text effortlessly. With minimal setup and a user-friendly approach, this script converts your audio into transcripts with a single command. Save time, eliminate setup hassles, and streamline your transcription workflow today!

Improvements and Fixes:

1. Version Comparison for Python:

The comparison of Python versions using if [[ “$PYTHON_VERSION” < “3.9” ]] may not work as intended because version strings aren’t directly comparable. Use sort -V for proper version comparison:

if [[ $(echo -e “$PYTHON_VERSIONn3.9” | sort -V | head -n1) != “3.9” ]]; then

2. Python Package Installation:

Use python3 -m pip instead of pip3 for consistency, especially since pip may not always be installed globally:

python3 -m pip install –upgrade pip

python3 -m pip install ffmpeg-python git+https://github.com/openai/whisper.git torch torchvision torchaudio –index-url https://download.pytorch.org/whl/cpu

3. Error Handling:

Add error handling for critical commands (e.g., Homebrew, Python, FFmpeg installation). Use || exit 1 to terminate the script if a step fails.

4. Script Portability:

The script is Mac-specific due to Homebrew. If portability is a concern (e.g., Linux users), you can check for package managers like apt or yum.

5. Processing Files:

If the $VOICE_DIR contains non-audio files, the loop will still attempt to process them. Add a check for supported file extensions:

if [[ “$EXT” =~ ^(mp4|mp3|wav)$ ]]; then

6. Temporary WAV Files:

Ensure temporary WAV files created during MP4 conversion are cleaned up to avoid clutter:

trap ‘rm -f “$VOICE_DIR/$BASENAME.wav”‘ EXIT

7. Dependencies Check Before Processing:

Ensure all dependencies are installed successfully before processing files. This avoids starting the transcription process if something is missing.

8. Improve Logging:

Use clearer messages and a log file to debug issues if needed:

LOG_FILE=”$HOME/transcriber.log”

echo “Starting script…” | tee -a “$LOG_FILE”

Updated Script:

#!/bin/bash

# Define folders

VOICE_DIR=”$HOME/voice”

TRANSCRIPT_DIR=”$HOME/transcript”

# Create folders if they don’t exist

mkdir -p “$VOICE_DIR” “$TRANSCRIPT_DIR”

# Log file

LOG_FILE=”$HOME/transcriber.log”

echo “Starting script at $(date)” | tee -a “$LOG_FILE”
