• Abstract summary: We introduce a LibriSpeech-PC benchmark designed to assess the punctuation and capitalization prediction capabilities of end-to-end ASR models. The benchmark includes a LibriSpeech-PC dataset with restored punctuation and capitalization, a novel evaluation metric called Punctuation Error Rate (PER) that focuses on punctuation marks, and initial baseline models.

• Abstract: Traditional automatic speech recognition (ASR) models output lower-cased words without punctuation marks, which reduces readability and necessitates a subsequent text processing model to convert ASR transcripts into a proper format. Simultaneously, the development of end-to-end ASR models capable of predicting punctuation and capitalization presents several challenges, primarily due to limited data availability and shortcomings in the existing evaluation methods, such as inadequate assessment of punctuation prediction. In this paper, we introduce a LibriSpeech-PC benchmark designed to assess the punctuation and capitalization prediction capabilities of end-to-end ASR models. The benchmark includes a LibriSpeech-PC dataset with restored punctuation and capitalization, a novel evaluation metric called Punctuation Error Rate (PER) that focuses on punctuation marks, and initial baseline models. All code, data, and models are publicly available.

  We investigate how different types of contextual information affect a model's ability to generate sentences with the desired readability. Results show that all tested models struggle to simplify sentences due to models' limitations and characteristics of the source sentences. Our experiments also highlight the need for better automatic evaluation metrics tailored to RCTS.

We achieved up to a 15.2% relative reduction in sentence error rate (SER) on a test set with contextually relevant entities.

  We investigate the text normalization routine employed by leading ASR models, including OpenAI Whisper, Meta's MMS, Seamless, and Assembly AI's Conformer. Our research reveals that current text normalization practices, while aiming to standardize ASR outputs for fair comparison, are fundamentally flawed when applied to Indic scripts. We propose a shift towards developing text normalization routines that leverage native linguistic expertise.

This paper proposes a reinforcement learning method to exploit in-topic written texts and recent advances in large pre-trained generative language models to bridge this gap.
