I don't know how, But They Found Me (BTFM).
btfm is a Discord bot that listens on a voice channel for key phrases, and plays audio clips into the channel in response.
Download the deepspeech native_client build for your platform, along with the acoustic model.
Set up your paths so that deepspeech can be found by the compiler (or drop it into /usr/local/lib/ and run ldconfig).
Install make, autotools, libopus headers, libsqlite headers, libsodium headers, and the openssl headers.
Create the data directory where the audio clips and database are stored. For example:
mkdir /var/lib/btfm/
Add clips and phrases with the btfm clip sub-commands:
btfm --btfm-data-dir /var/lib/btfm/ add "they found me" "I don't know how, but they found me..." run-for-it-marty.mp3
See btfm clip --help for available sub-commands and options.
Start the bot with btfm run. Parameters are accepted via CLI arguments or
environment variables. For example, a systemd unit file to run the service
under the "btfm" user (which should be able to read /var/lib/btfm/):
```
[Unit]
Description=BTFM Discord bot
After=network.target
[Service]
Type=simple
User=btfm
Group=btfm
Environment="BTFMDATADIR=/var/lib/btfm/"

Environment="DISCORDTOKEN=
[Install] WantedBy=multi-user.target
[Install] WantedBy=multi-user.target ```
See btfm run --help for command line arguments and documentation. To
obtain the guild and channel ID, go to your Discord User Settings ->
Appearance, and enable Developer Mode. You can then right-click on the server
for and select "Copy ID" for the guild ID, and then right-click the voice
channel you want the bot to watch and "Copy ID" that as well.
If you are so inclined, there is a Dockerfile and some helper scripts in the devel/ folder
that you may find to be handy for development. The scripts assume you have
podman installed. You can use build.sh to build a development container,
and you can use cargo.sh to run Rust's cargo tool inside
the container. You can probably guess what test.sh does, if you are somebody's kid and are
smart.
