# Whisper

Since you are now officially a Fly.io expert, let's dive right in and run the following two commands in the project directory of your deep dive demo app:

```
fly launch --attach --from https://github.com/rubys/cog-whisper
fly deploy
```

Next try capturing a new audio clip. It will be transcribed automatically by OpenAI Whisper, an automatic speech recognition (ASR) program that converts speech into text.

## What just happened

You provisioned a new Machine, this time with an [L40S](https://www.nvidia.com/en-us/data-center/l40s/) GPU.
It will stop when not in use. It will restart when a new request comes in.
It is only available on the private network using [Flycast](/networking/flycast).

It runs [OpenAI Whisper](https://openai.com/index/whisper/) accessed via a [COG](https://github.com/replicate/cog) interface.

This process involves taking audio clips from Tigris, passing them to Whisper, and updating Postgres with the results.
The Node code for this is about [two dozen lines of code](https://github.com/fly-apps/node-dictaphone/blob/1e84a4dece6888dfc68880d146b46511d47391b3/app.js#L102-L129),
and for Rails is about a [dozen](https://github.com/fly-apps/rails-dictaphone/blob/6bdf4f639640c9fb55530546dbbed682b65a7df9/app/jobs/whisper_transcribe_job.rb#L5-L16).

And, as always, there's no lock in. You can opt to replace this with a machine hosted by [Replicate](https://replicate.com/) or elsewhere.
