Abstract

With the development of the Internet, voice files have become more and more accessible files. How to efficiently extract the key information from a recording, extract the content that people are interested in, and intuitively present it to the human door.

This paper presents a Python-based speech recognition system, in which the TensorFlow model is introduced. The main purpose of this system is to realize the recognition of speech data in different languages, and to transform it into computer-operable text data. First, we built a deep neural network model using the Python language and the TensorFlow framework for the feature extraction and classification of the input speech data. During the model training process, we used a large number of data sets for training, and the model was constantly optimized and adjusted to improve its identification accuracy and efficiency. Second, we combined a trained model with hands-on application and wrote a speech recognition system based on Python. The system uses the audio input equipment, such as the microphone, to collect and recognize the voice input by the user, and outputs the recognition results into text data. Finally, we experiment and test the system, and the results show that the system can effectively identify the speech data of different languages, and has high recognition accuracy and response speed, which can meet the needs of practical applications. In summary, we propose a Python-based speech recognition system in which the TensorFlow model is introduced.

The system has high efficiency, accuracy and scalability and can be widely used in various practical application scenarios.
