New benchmark standardizes forced alignment and ASR evaluation

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced FA-Bench, a new open framework designed to standardize the evaluation of forced alignment and automatic speech recognition (ASR) systems. This benchmark addresses inconsistencies in previous comparisons by unifying protocols for transcript normalization, data splitting, and boundary matching across various models. FA-Bench includes results for 21 open-source models and 9 commercial APIs, tested on both clean and noisy speech, with a focus on accurate timestamp estimation at word and phone levels. AI

IMPACT Standardizes evaluation for speech-to-text technologies, enabling more reliable comparisons of ASR and forced alignment systems.

    FA-Bench: A Benchmark for Phone- and Word-Level Timestamp Accuracy in Forced Alignment and ASR on Clean and Noisy Speech

    arXiv:2609.32396v2 Announce Type: replace Abstract: Forced alignment estimates the timestamps of each word, phone or character in speech given its transcript. Published comparisons normalize transcripts, split the data and match boundaries differently, so their numbers cannot be …
