Conducting Reliable Keyword Estimation with Unreliable ASR in Police Audio Data

Extracting insights from large audio data sets using human transcription is expensive and time-consuming. Off-the-shelf Automatic Speech Recognition (ASR) systems offer an easy-to-use scalable alternative, but systematic transcription errors, especially in domain-specific settings, can bias downstream analyses and lead...

Pretrained ASR Pseudo-labeling for Noisy Police Audio

This work systematically assess the opportunities and limits of pseudo-labeling to adapt foundation ASR models (Whisper and Qwen3-ASR) to noisy BPC domain corpora from Baltimore and Chicago and introduces a new cross-model pseudo-labeling paradigm where one model is finetuned with pseudo-labels from the other.
