Choose jiwer if…
- Tags unique to jiwer: automatic-speech-recognition, evaluation-metrics, python3, speech-to-text.
- For accurate speech recognition evaluation needing direct WER calculations
- More GitHub stars (917 vs 72) - visibility, not fit.
When NOT to use jiwer
- Avoid if your project requires only basic, non-word level performance indicators
- Not suitable for evaluating text-to-speech systems, as it focuses exclusively on speech-to-text output assessment
Choose langevals if…
- Tags unique to langevals: evaluation, guardrails, llm, openai.
- When you need a singular point of access to multiple LLM evaluation tools
- Leaner open-issue backlog (18).
When NOT to use langevals
- If you prefer not having a dependency on LangEvals after it has been moved into the LangWatch monorepo, opting for directly managing individual evaluators could be a better option
- When needing to customize evaluation processes extensively beyond what the provided standard interface allows
