Dear all,

On Wednesday (8 Oct), Jan Chorowski will tell us about his latest work on
building an end-to-end speech recognition system using attention mechanism.
This work has been submitted to NIPS Deep Learning Workshop 2014, and the
submitted manuscript is attached.

Hope to see many of you there!

- Title: End-to-end Continuous Speech Recognition using Attention-based
Recurrent NN: First Results
- Spaker: Prof. Jan Chorowski, University of Wrocław, Poland
- Date and Place: 13.30-14.30, 8 Oct (Wednesday) @AA3195
- Abstract:
We replace the Hidden Markov Model (HMM) which is traditionally used in in
continuous speech recognition with a bi-directional recurrent neural
network en- coder coupled to a recurrent neural network decoder that
directly emits a stream of phonemes. The alignment between the input and
output sequences is established using an attention mechanism: the decoder
emits each symbol based on a context created with a subset of input symbols
selected by the attention mechanism. We report initial results
demonstrating that this new approach achieves phoneme error rates that are
comparable to the state-of-the-art HMM-based decoders, on the TIMIT
dataset.
