Phonologically Informed Tokenization for German Speech Recognition: A Cross-Domain Study

German is a morphologically rich language whose syllable structure is exceptionally well-predicted by the Knuth--Liang hyphenation algorithm. We ask whether phonologically informed tokenization can serve as a competitive target for end-to-end speech recognition. We compare three tokenizer families on the Omnilingual AS...

The Spoken Wikipedia Presentation Corpus

We present the Spoken Wikipedia Presentation Corpus, an extension of the Spoken Wikipedia Corpora featuring LLM-generated slide decks for multimodal ASR. Slides are created from LLM-segmented sections using a hybrid pipeline that combines LLM-based content planning with rule-based design decisions. For each section, an...

Reusing Latent Speech Representations for Query-Conditioned Topic Localization in Transcripts

To improve span localization, ASR encoder states are reuse ASR encoder states as sentence-level representations and fuse them with textual embeddings to let lightweight span locators exploit speech information without running a separate audio encoder.
