Embodiment Construction

[0042] Taking the agricultural product price information query service in a certain area as an example, the training voices were collected and trained in large-scale agricultural product wholesale markets, community farmer’s markets, supermarkets, agricultural product processing workshops, etc., including 20 males and 20 females, and the recorded short sentences included 200 The names, prices, origins, grades, etc. of various agricultural products are pronounced in Mandarin with a slight local accent. A total of 8,400 short sentences were collected for about 2 hours as a training set. The test set recorded 3 males and 3 females with 50 sentences each, a total of 300 sentences, which were recorded by mobile phones in a relatively quiet environment as approximately pure speech, and the speakers were not in the training set. Then artificial noise is added to the noise of the large-scale agricultural product wholesale market environment, and finally the noisy speech with signal-to-...
