Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] combine figure 1 and figure 2 , the present invention provides a non-contact speech perception synthesis device, which mainly includes two parts: a vocal cord vibration sensing module and a speech perception synthesis module. The vocal cord vibration sensing module is used to obtain the vocal cord vibration frequency of the subject; the speech perception synthesis module is used to perform speech synthesis on the subject's vocal cord vibration frequency obtained by the vocal cord vibration sensing module through harmonic synthesis, and finally obtain the restored sound information.

[0019] The vocal cord vibration sensing module includes a radar signal transmitting module, a radar signal receiving module and a digital signal processing module, and the radar signal analog receiving module is connected with the radar signal transmitting module and th...

Abstract

The invention discloses a non-contact type voice perception synthesis device. The non-contact type voice perception synthesis device comprises a vocal cord vibration sensing module and a voice perception synthesis module; the vocal cord vibration sensing module is connected with the voice perception synthesis module and extracts the vocal cord vibration frequency of a tested person; and the voice perception synthesis module conducts voice synthesis on the vocal cord vibration frequency of the tested person with the harmonic synthesis method. The non-contact type voice perception synthesis device is small and exquisite in size, convenient to install, high in measurement accuracy and tiny in transmitting power; any harm or side effect on the tested person can be avoided; medical workers can conveniently take corresponding medical treatment measures in time according to the actual conditions of vocal cord vibration; and a patient with voice disorders can be assisted.

Description

technical field [0001] The invention belongs to the field of speech perception, in particular to a non-contact speech perception synthesis device. Background technique [0002] Speech has always been the most effective way of human communication. Since 1960, scientists and engineers have done a lot of research on speech signal processing, such as speech coding and synthesis, speech recognition, speaker verification and Recognition, etc., but these technologies are mostly based on data information from hearing sounds. A large number of experiments have proved that vocal cord vibration can provide relevant information about human vocalization. At present, speech perception synthesis is mostly based on technologies such as phonograms and real-time images, which cannot meet the requirements of real-time, accuracy, miniaturization and intelligence. The non-contact speech perception synthesis device involved in the present invention can monitor the vibration of human vocal cords ...
