Investigating Gated Recurrent Networks for Speech Synthesis
Table 1: Subjective preference scores (%). p<0.01 indicates significant difference between the two systems.
['[EMPTY]', 'LSTM', 'NIG', 'NOG', 'NFG', 'NPH', 'GRU', 'S-LSTM', 'Neutral', 'p-value']
Comparing against the LSTM system, all the systems except NFG show no significant difference in preference.
