These measures are commonly used to measure the performance for an automatic speech recognition (ASR) system. The following measures are implemented: - Word Error Rate (WER), which is where this library got its name from. This has long been (and arguably still is) the de facto standard for computing ASR performance. - Match Error Rate (MER) - Word Information Lost (WIL) - Word Information Preserved (WIP) - Character Error Rate (CER) Note that these functions merely call [jiwer.process_words][process.process_words] and [jiwer.process_characters][process.process_characters]. It is more efficient to call `process_words` or `process_characters` and access the results from the [jiwer.WordOutput][process.WordOutput] and [jiwer.CharacterOutput][process.CharacterOutput] classes.
