Confusing line in configuration.yaml in tutorial

[KotBayun69]

There is a part in the tutorial where faster-whisper is set up

asr:
    faster-whisper: ...
    faster-whisper.client:
      command: |
        client_unix_socket.py var/run/faster-whisper.socket

The second line is confusing (at least for me). I was assuming I should keep previous created entry forfaster-whisper: ... and add another for faster-whisper.client. Which apparently was wrong.

another issue I have had is in piper setup.

template_args:
        model: "${data_dir}/en-us-blizzard_lessac-medium.onnx"

I don't know why, but my file name was different: en-us-lessac-low.onnx . I spend some time trying to understand why am I getting an error when running the script
