whisper-audio-transcriber

name	whisper-audio-transcriber
description	Use when you need to transcribe a local audio file with whisper-cpp. The skill creates a timestamped folder next to the source audio, copies the original file there, converts it to a Whisper-friendly WAV, and writes a plain-text transcript. Default language is Italian; optionally force English.

Whisper Audio Transcriber

Use this skill for one-off local transcriptions with whisper-cli and ffmpeg.

Default language is Italian. Use English only when the source audio is clearly in English.

Workflow

1. Confirm the input audio path.
2. Run scripts/transcribe_audio.sh with the audio path.
3. By default, do not pass a language flag, so the script uses Italian.
4. If the user says the audio is in English, pass --language en.
5. Return the output folder path and the transcript path.

Command

Italian by default:

/Users/mameli/.codex/skills/whisper-audio-transcriber/scripts/transcribe_audio.sh /absolute/path/to/file.m4a

Force English:

/Users/mameli/.codex/skills/whisper-audio-transcriber/scripts/transcribe_audio.sh --language en /absolute/path/to/file.m4a

Optional model override:

/Users/mameli/.codex/skills/whisper-audio-transcriber/scripts/transcribe_audio.sh --model /Users/mameli/Ai_models/ggml-medium.bin /absolute/path/to/file.m4a

Output Layout

The script creates a folder next to the source file with this naming pattern:

YYYY-MM-DD_HH-MM_file-name/

Inside it, write:

• the original audio file
• *_whisper.wav converted to mono, 16 kHz, pcm_s16le
• *_transcript.txt as plain text

Requirements

• ffmpeg
• whisper-cli
• a local GGML model, defaulting to /Users/mameli/Ai_models/ggml-medium.bin when present

If the default model is missing, pass --model.

Notes

• Keep the transcript as plain text only. Do not request subtitle output unless the user asks.
• If the input audio is already WAV, still place all generated files inside the timestamped folder.
• If language is not specified by the user, use Italian.
