Texterrors WER/CER Scoring Tool

texterrors is a Python library and command-line tool designed to score ASR (Automatic Speech Recognition) or transcription output against a reference. It provides metrics such as Word Error Rate (WER) and Character Error Rate (CER), supports standard and character-aware alignment, generates detailed error reports, and can produce colored output for inspection. The library also features comparison of multiple hypothesis files, per-group metrics (e.g., per-speaker WER), keyword and OOV (Out-Of-Vocabulary) evaluation, oracle WER, and simple entity accuracy. It aims to be an easy-to-use, modify, and extend alternative to older tools like `sclite`. The current version is 1.1.6, and it receives active maintenance and frequent updates.
