# Generate subtitles locally using Whisper

```bash
#!/bin/bash
# Single script to convert a file to wav and have it be transcribed by whisper

# Check if a filename is provided as an argument
if [ -z "$1" ]; then
  echo "Usage: $0 <filename>"
  exit 1
fi

fileName="$1"

# If the file is not already a WAV file, convert it
if [[ $(file -b --mime-type "$fileName") != audio/wav ]]; then
  echo "Converting to WAV file"
  # Modify the conversion command as needed
  ffmpeg -i "$fileName" -acodec pcm_s16le -ar 16000 "$(basename "$fileName" .${fileName##*.}).wav"
  convertedFileName="$(basename "$fileName" .${fileName##*.}).wav"
else
  convertedFileName="$fileName"
fi

if [ ! -f "$convertedFileName" ]; then
  echo "Error: Conversion failed."
  exit 1
fi

# Transcribe the WAV file
echo -e "\n\n\nTranscribing..\n\n\n"
~/code/whisper.cpp/main -osrt -m /Users/aldrinjenson/code/whisper.cpp/models/ggml-medium.en.bin "$convertedFileName" && echo "Transcribed successfully" || echo "Error in transcribing!"

```

### Next steps:

Add the above script to path

P.S. Do remember to change the path of whsiper.cpp to the correct location in your computer.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://til.aldrinjenson.com/ai-and-llms/generate-subtitles-locally-using-whisper.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
