Problems solved by technology

This greatly limits the scope of use of the system, and according to the context, it is a speech recognition system with a large number of vocabulary and continuous speech, so it takes a lot of time from speech collection to making a model library

Embodiment Construction

[0024] The technical solution of the invention will be specifically described below in conjunction with examples and accompanying drawings.

[0025] figure 1 is a schematic diagram of the teleprompter system. Such as figure 1 As shown, the system includes a main controller, a display, a wireless microphone, a wireless voice receiving recognition module, a user setting button circuit, a preset text access circuit and a USB interface circuit. The functions of each part and the relationship between each part will be described in detail below.

[0026] The wireless microphone 1, also called a wireless microphone, can be used to receive voice signals, and the voice signals will be sent wirelessly to the space environment after being processed. The specific process is that the wheat head of the wireless microphone uses a capacitor column collective, and the capacitance of the wheat head will change when receiving sound pressure. The microphone head is connected to the osci...

Abstract

A prompt device with a voice recognition function comprises a main controller, a display, a radio microphone, a radio voice receiving and recognizing module, a user-setting button circuit, a preset text accessing circuit and a USB (universal serial bus) interface circuit. The radio microphone receives voice signals from a speaker or announcer, the received voice signals are transmitted to the corresponding voice signal receiving and recognizing module wirelessly. The voice signal receiving and recognizing module converts the voice signals into texts to be transmitted to the main controller by processing of voice recognition technology of independent persons, continuous voice and many words; the main controller compares the texts with sentences in the preset texts to find out this sentence, and finally the display displays this sentence with double underlines, color and bolding and the following content is displayed by amplified, colored and bolded texts. The announcer can focus on broadcasting by the aid of the prompt device, and broadcasting quality can be improved.

Description

technical field : [0001] The invention belongs to the field of signal processing, in particular to a word prompting device with a speech recognition function. Background technique: [0002] In the 1980s, with the successful application of technologies such as the HMM model and artificial neural network (ANN) in speech recognition, people finally broke through the three major speech recognition barriers of non-specific people, large vocabulary and continuous speech in the laboratory. On September 12, 2013, HKUST Xunfei launched an offline voice input software that supports Mandarin - Xunfei Input Method. Offline voice will be directly embedded in the Xunfei input method, and users can use voice input without being connected to the Internet by downloading a 15.39M offline voice package. Xunfei Input Method is the first input method that supports offline voice. The recognition rate of offline speech is slightly lower than the 95% recognition rate of the cloud-based Xunfei ...
