Beyond Word Count: Exploring Approximated Target Lengths for CIF-RNNT
Wen Shen Teo, Yasuhiro Minami (UEC) SP2024-5
Abstract (in Japanese) (See Japanese page) 
(in English) Our previous work proposed the CIF-RNNT architecture, a combination of Continuous Integrate-and-Fire (CIF) and RNN-Transducers (RNN-T) that compresses speech into units equivalent to linguistic words to achieve efficient decoding. This work extends on that research by investigating the impact of different target length definitions, approximated from self-information and token count. Our results on LibriSpeech and CSJ show that approximated target length types based on self-information outperform simpler approaches, and CIF-RNNT models even surpass topline models on the CSJ dataset at smaller chunk sizes. Furthermore, our comparisons demonstrate an inherent ability of CIF-RNNT to produce output tokens in groups of words, regardless of the target length type. These results showcase the potential of the CIF-RNNT architecture for efficient and accurate speech recognition.
