Description

LDC93S1 prod model outputs vary wildly across versions of the prod model and our inference runtime, because we don't train with anything like TIMIT, so predictions are not confident. We should use some sample from eg. LibriSpeech that will be more stable across changes to prod model and avoid wasting time waiting for test results every time something has to be changed there.

Contributor guide

Research direction
Find the test file that uses LDC93S1 sample, understand the test setup, and replace it with a sample from LibriSpeech that yields consistent results across model versions.
