Introduction to Transcribe Speech recognition technology, also known as Automatic Speech Recognition (ASR), aims to convert the lexical content in human speech into computer-readable input, such as keystrokes, binary codes, or character sequences. Speech recognition technology has been developing for decades. It was not until 2009, when Hinton introduced artificial intelligence deep learning solutions into […]

Vue uses websocket to implement real-time data push and publish, subscribe and reconnect single sign-on functions.
Requirements: Use websocket to implement publishing, subscribing, network disconnection and reconnection, and account squeezing after single sign-in without using plug-ins. 1. Single sign-on (only one of the same account is online at the same time, multiple user logins are prohibited) Implementation: After the user logs in, the token token is obtained and stored locally. It […]

Describe in detail the execution process of js and the execution principle of javascript
Hello everyone, the editor is here to answer the following questions for you, explain in detail the execution process of js and the execution principle of javascript. Now let us take a look together! Foreword JavaScript The execution process is divided into two stages, the compilation stage and the execution stage. During the compilation phase, […]
Subscriber of Fast DDS
Directory Subscriber SubscriberQos SubscriberListener Create Subscriber DataReader SampleInfo Read data Get data through callback Processed by starting a waiting thread Subscriber plays the role of a container, and there can be many DataReaders in it. They use the same SubscriberQos configuration of Subscriber. Subscriber can carry DataReader objects of different Topics and data types. Subscriber […]
Use the Redis publish and subscribe function to implement dynamic registration monitoring and asynchronous retrieval of results
Introduction and objectives Publish/subscribe is very commonly used in our system development. Redis also provides this function, but it implements relatively basic functions. Redis cannot achieve these functions of reliable message publishing, subscription and message accumulation. But we can still use it to handle many business scenarios, such as: Our system uses services to call […]
Subscribe to topics from rosbag–take images as an example
This article is a supplement to the CSDN blog that uses the subscription function of ROS topics to extract information from bag files_rosbag extracts multiple topic information. ROS creates workspace code with one click conda deactivate # if necessary # Check path echo “the current space is ” pwd #Initialize workspace mkdir -p ./rosbag-ext/src cd […]
Establishment of adjacency matrix and adjacency list of graph, described by c/c++
The data nodes in the graph have a many-to-many relationship. A node has multiple predecessors and multiple successors. There are even undirected graphs that do not distinguish between predecessors and successors, and only require adjacency relationships between nodes. Therefore, describing this data relationship requires a new data structure. A graph consists of a vertex set […]
Use the Redis publish-subscribe model to implement session sharing
In fact, it is not to realize session sharing, but to use redis publish and subscribe, so that all cluster servers can send messages to their own sessions. For example, if userId is on the 35th server and there are 100 servers, then the first server receives the message and needs to notify userId. Instead […]
