# This scripts run the selected model agains a collection of audio files from the web.
|
|
# It downloads, converts and transcribes each file and then compares the result with the expected reference
|
|
# transcription. The comparison is performed using git's diff command and shows the differences at the character level.
|
|
# It can be used to quickly verify that the model is working as expected across a wide range of audio files.
|
|
# I.e. like an integration test. The verification is done by visual inspection of the diff output.
|
|
#
|
|
# The reference data can be for example generated using the original OpenAI Whisper implementation, or entered manually.

# Make sure they are between 1-3 minutes long since we don't want to make the test too slow.
