Problems solved by technology

[0004] In recent years, with the upsurge of deep learning rising again, the research on the speech recognition system based on deep neural network has been hot. At present, the best speech recognition system uses a bidirectional long short-term memory network (LSTM, Long Short Term Memory), but this Due to the high complexity of system training and long decoding time, it is difficult to be widely used in industrial real-time recognition systems, especially in the environment of huge noise in factories.

Embodiment Construction

[0027] The present invention will be further described below in conjunction with specific examples.

[0028] Such as figure 1 As shown, the deep learning-based intelligent industrial robot voice interaction and control method described in this embodiment includes the following steps:

[0029] 1) Speech is converted into a spectrogram, and the original speech is converted into an image that can be used as an input by the short-time Fourier transform FFT method, specifically: using the short-time Fourier transform FFT method for each One frame is processed, and the spectrogram composed of time domain and frequency domain is obtained through time extraction algorithm and frequency extraction algorithm. In the process of frequency extraction, unnecessary frequencies are compressed to reduce the impact of noise .

[0030] 2) To model the entire sentence speech, input the spectrogram obtained in step 1) as a feature map into a neural network composed of multiple convolutional laye...

Abstract

The invention discloses a deep learning-based intelligent industrial robot speech interaction and control method. The method comprises the following steps that: 1) speech is converted into a speech spectrum: original speech is converted into an image through FFT (Fast Fourier Transformation), wherein the image can be used as input; 2) modeling is performed on the whole speech sentence: the speech spectrum, adopted as input, is utilized to perform unsupervised training on a convolutional neural network; 3) the output sequence O of the convolutional neural network is compared with a tag T, and the convolutional neural network is adjusted in a supervised manner through the BP algorithm; and 4) specific text information is inputted into a robot as a control command. According to the deep learning-based intelligent industrial robot speech interaction and control method of the invention, the speech recognition technology and the industrial robot are combined together, and therefore, a traditional production mode is changed, the labor intensity of workers is decreased, labor productivity is enhanced, and the intelligentization development of industrial technologies can be promoted.
