Hi, I don't have specific numbers to share (as I said the online decoder is not rigorously tested as far as I know). In principle I think the online decoder should perform slightly worse than the offline versions due to things like online CMN computation. What do you mean exactly when you say that the results for the online demo are not so good? As far as I remember the WER for the test WAV files was about 7%, which is not so bad as today's speech recognition goes. Of course the WER in this case is so low, because the language model is relatively small and perfectly matches the test files (the LM is trained on the text corresponding to the audio book from which the test utterances were taken - not the best practice of course).
