The invention provides a voice conversion scheme for non-parallel corpus training to get rid of dependence on parallel texts and solve the technical problem of difficult realization of voice conversion under the condition that resources and equipment are limited. The invention relates to a voice conversion system, method and an application terminal. Compared with the prior art, the scheme has theadvantages that: a trained speaker-independent voice recognition model can be used for any source speaker, namely the speaker is independent; the bottleneck characteristics of the audio are more abstract than voice phonetic posterior Gram characteristics, can reflect the speaking content and decouple from the tone of the speaker, and are not closely bound with the phoneme category, and are not ina clear one-to-one correspondence relationship, so that the problem of inaccurate pronunciation caused by ASR recognition errors is relieved to a certain extent. The pronunciation accuracy of the audio obtained by performing voice conversion by using bottleneck characteristics is obviously higher than that of a voice phonetic posterior Gram method, and the tone is not obviously different; by meansof a transfer learning mode, dependence on training corpora can be greatly reduced.

The invention provides a method for generating real-time road condition information. The method includes: automatically listening to the broadcast; performing speech recognition on the broadcast signal, performing keyword detection, extracting road condition information from it, and converting it into text information; using natural language processing technology, which converts text information into map feature language, draws and feeds back in map products, and forms traffic condition information. Correspondingly, the present invention also provides a system for generating real-time road condition information. The present invention can provide real-time traffic information for users in a wide area, based on which a series of applications such as navigation and travel planning can be performed, and a lot of manpower can be saved for road condition product providers.

The invention relates to a down-hole information acoustic wave signal relay system. The down-hole information acoustic wave signal relay system comprises an upper connector, an instruction bin protective cylinder and a lower connector which are sequentially connected. An energy converter protective cylinder, an instrument bin and an accelerometer protective cylinder which are sequentially connected are arranged in the instruction bin protective cylinder. The end of the energy converter protective cylinder is matched with the upper connector, and the end, connected with the accelerometer protective cylinder, of the instrument bin is connected with the end of the instruction bin protective cylinder. The end of the accelerometer protective cylinder is matched with the lower connector, and an energy converter is installed in the energy converter protective cylinder. A circuit module is arranged in the instrument bin and comprises an energy converter driving circuit, a coding and transcoding circuit and a decoding circuit, and an accelerometer is arranged in the accelerometer protective cylinder. According to the down-hole information acoustic wave signal relay system, while normal well drilling is kept, real-time receiving of acoustic wave signals carrying well drilling information and from the lower portion of a drilling pillar is achieved; the effective signals are enlarged and then occurs again, long-distance stable transmission of the well drilling information is achieved, and the damping problem when the acoustic wave signals carrying the well drilling information are transmitted is solved; and drilling fluid and a stratum are not relied on, the noise interference resistance capacity is high, real conversion of the well drilling information is achieved, and the application range is wide.
