H_eval: A new hybrid evaluation metric for automatic speech recognition tasks

no code implementations3 Nov 2022 Zitha Sasindran, Harsha Yelchuri, T. V. Prabhakar, Supreeth Rao

We propose H_eval, a new hybrid evaluation metric for ASR systems that considers both semantic correctness and error rate and performs significantly well in scenarios where WER and SD perform poorly.
