Chunk-wise Attention Transducers for Fast and Accurate Streaming Speech-to-Text

Hainan Xu, Vladimir Bataev, Travis M. Bartley +1

We propose Chunk-wise Attention Transducer (CHAT), a novel extension to RNN-T models that processes audio in fixed-size chunks while employing cross-attention within each chunk. Th…
