Wherein the terminal 110 communicates with the server node 120 via a network, and the server node 120 communicates with the cache server 130. The terminal 110 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server node 120 may be implemented by an independent server or a server cluster formed by a plurality of servers.
The terminal 110 sends a voice recognition request for realizing voice recognition to the server node 120 in the cluster environment, the server node 120 generates session related information and sends the session related information to the cache server 130 after receiving the session related information, and the cache server 130 receives the session related information and runs script codes.

If the current session number is smaller than the session number threshold, the cache server 130 increases the current session number through the script code and returns a first result to the server node 120. Upon receiving the first result, serving node 120 may create a voice recognition session with terminal 110.
In one embodiment, as shown in fig. 2, a session processing method in a cluster environment is provided, which may be applied to a system including a cache server and a server node and implemented by interaction between the cache server and the server node, and includes the following steps:
s202, after the server nodes in the cluster receive the connection request for realizing the voice recognition, the cache server receives the session related information sent by the server nodes aiming at the connection request.
The voice recognition is to convert voice into text. The cluster includes a plurality of server nodes. A cache server is a server that hosts frequently accessed content. The server node can communicate with different application programs of a plurality of terminals and receive voice recognition connection requests sent by the different application programs. The application program referred to in the present application refers to an application program that requires language identification and is executed on a terminal. Specifically, an application program on the terminal sends a voice recognition connection request to the server node, and based on the voice recognition request, the server node can confirm a service corresponding to the request, acquire information related to the service, obtain session related information, and send the session related information to the cache server.
In one embodiment, the cache Server may be a Redis (Remote Dictionary Server, a type of non-relational database across platforms) Server that installs a Redis service. It is understood that in addition to the Redis server, other technically implemented servers capable of hosting frequently accessed content may also be referred to as cache servers. The server node may execute a command of the client corresponding to the Redis service, and use the session related information as a parameter of the command, where the parameter of the command is received by the Redis service of the cache server, that is, the session related information sent by the server node is received by the cache server.
In one embodiment, the session related information includes at least one of a user identifier, a service identifier, a session number threshold, and the like.
In one embodiment, the voice recognition request includes at least one of a terminal identifier and an application name, wherein the terminal identifier refers to a unique identifier of a terminal on which the application is running. The server node generates a user identifier based on at least one of the terminal identifier, the server node identifier, the application name, and the like. In one embodiment, the terminal identification and the server identification may be MAC addresses of the corresponding devices.
S204, the cache server runs script codes; determining the current session number of the established session under the service of the connection request based on the session related information through the script code; and acquiring a session number threshold corresponding to the service recorded in the session related information, and comparing the current session number with the session number threshold through the script code.
The Script (Script) is an executable file written according to a certain format using a specific descriptive language. The script code includes processing logic for the caching server based on the session-related information.
In one embodiment, the script executed by the cache server is a lua script, which is a small script language. The execution of the lua script by the cache server is atomic, and the next lua script can be continuously executed after the execution of the lua script by the cache server is finished once.
Specifically, the cache server stores the current session number of the created session corresponding to each service. The cache server can obtain the corresponding current conversation quantity by running the script code, and compares the current conversation quantity with the conversation quantity threshold value in the conversation related information, thereby judging whether the voice recognition conversation is agreed to be created.
In one embodiment, the cache server may determine that it is approved to create a speech recognition session if the number of current sessions is less than the number of sessions threshold.
In one embodiment, the cache server may determine that the speech recognition session is not approved for creation if the current number of sessions is equal to the threshold number of sessions.
In an embodiment, if the interaction frequency with the server node is greater than a preset value and the current session number is equal to the session number threshold, the cache server may determine that the creation of the voice recognition session is not approved, notify the server node to suspend the interaction, and wait for a preset duration or continue the interaction after receiving a message that the interaction can be continued.
In one embodiment, if it is determined that the voice recognition session is approved to be created, the cache server may update the current session number of the corresponding service.
It can be understood that due to the atomicity characteristic of the lua script, the cache server reads and updates the current session number based on the lua script, the accuracy of the data is guaranteed, and errors of related data caused by asynchronous operation among a plurality of server nodes can be avoided. And the processing to be executed can be completed by executing the lua script once without multiple interactions, thereby improving the system performance and reducing the system pressure.
S206, if the current session number is smaller than the session number threshold value, increasing the current session number through the script codes, and returning a first result to the server node; a first result indicating that a voice recognition session is created for the connection request.
Specifically, if the cache server judges that the current session number is smaller than the session number threshold, the cache server adds one to the current session number and returns a first result to the server node, and the server node receives the first result and creates a voice recognition session with the application program.
It can be understood that the server node creates the speech recognition session according to the first result returned by the cache server, so that the cache server limits the total number of sessions created by a plurality of server nodes for the same service, thereby playing a role of centrally controlling the total number of sessions in the cluster environment,
according to the session processing method under the cluster environment, after the server node in the cluster receives the connection request for realizing the voice recognition, the server node sends the session related information aiming at the connection request to the cache server. The cache server runs script codes, determines the current session number of the created session under the service of the connection request based on the session related information, acquires a session number threshold value corresponding to the service recorded in the session related information, and compares the current session number with the session number threshold value through the script codes; and if the current session number is smaller than the session number threshold value, increasing the current session number through the script codes, and returning a result for indicating that the voice recognition session is created aiming at the connection request. The processing performed by executing the script code is atomic and is not interrupted by other server nodes in the process of executing the script code. Therefore, according to the scheme of the application, the server node sends the session related information to the cache server, and the script code is combined, so that the number of the service sessions can be limited only by connecting and running the script once, the connection times are greatly reduced, and the system performance is improved.
In one embodiment, the method further comprises: after receiving the first result, the server node creates a voice recognition session aiming at the connection request; a voice recognition session, which is a session for realizing voice recognition; the server node performs voice recognition based on the created voice recognition session.
Specifically, after the server node receives the first result, the server node creates a session for implementing voice recognition, and the user may generate voice information using an application program on the terminal, and the application program sends the voice information to the server node based on the voice recognition session. The server node may perform a speech recognition algorithm to perform speech recognition on the speech information received by the session, and return a speech recognition result to the application program on the terminal based on the session after performing the speech recognition algorithm.
In one embodiment, the server node may establish speech recognition sessions with applications on multiple terminals, execute speech recognition algorithms in sequence in one thread and return speech recognition results to the applications on the terminals.
In another embodiment, the server node establishes speech recognition sessions with different applications on a plurality of different terminals, one application on one terminal corresponding to one thread, each thread executing a speech recognition algorithm and returning speech recognition results to the corresponding application on the terminal.
In this embodiment, the server node creates a speech recognition session after receiving the first result, performs speech recognition, and is limited to the returned result of the cache server. In the cluster environment, whether a voice recognition session is created or not is indicated by a unique cache server according to the number of sessions, so that the accurate limitation of the cluster environment on the session number threshold of the service is ensured.
In one embodiment, the method further comprises: if the current session number is equal to the session number threshold value, the cache server returns a second result; a second result indicating that the connection request is not responded to; and after receiving the second result sent by the cache server, the server node does not respond to the connection request for realizing the voice recognition.
Specifically, the server node does not create a speech recognition session with the application program on the terminal upon receiving the second result, and sends a connection failure result to the application program on the terminal.
In one embodiment, the server node may send a timeout duration to the application on the terminal, and the application on the terminal waits for the timeout duration before initiating the connection request again.
In an embodiment, the server node obtains the second result, may determine that the current session number is equal to the session number threshold, and after waiting for a timeout period, the server node sends the session related information to the cache server based on the connection request of the terminal.
In this embodiment, the server node knows that the current session number is equal to the session number threshold based on the second result, and rejects to create the voice recognition session, thereby ensuring accurate limitation of the cluster environment on the session number threshold of the service, and avoiding too frequent connection request initiation due to the fact that the current session number is equal to the session number threshold, thereby reducing the pressure of the system.
In one embodiment, the session related information sent for the connection request is first session related information; the current session number of the established session under the service of the connection request is the first current session number; as shown in fig. 3, the method comprises the steps of:
s306, after the server node in the cluster receives the session disconnection request aiming at the created voice recognition session, the cache server receives second session related information sent by the server node aiming at the session disconnection request.
The second session related information includes at least one of a user identifier and a service identifier.
Specifically, when the application program on the terminal does not need to continue voice recognition, a session disconnection request is sent to the server node, and the server node sends second session related information to the cache server based on the session disconnection request.
S304, the cache server runs script codes; and determining a second current session number of the created sessions under the service to which the session disconnection request belongs through the script code based on the second session related information.
Specifically, the cache server obtains a service identifier and a user identifier based on the second session related information. And the cache server searches and obtains the current session number corresponding to the service based on the service identifier.
In an embodiment, the cache server does not find the current session number corresponding to the service identifier, does not execute step S306, and directly returns the session closing result.
In one implementation, the cache server does not search for the user identifier from the user identifier set, and does not perform step S306, and directly returns the session closing result.
S306, reducing the number of the second current sessions through the script codes, and returning a session closing result; a session close result indicating that the voice recognition session for which the session disconnection request is directed is closed.
Specifically, the cache server reduces the number of current sessions corresponding to the service, and deletes the user identifier from the user identifier set. And returning a session closing result to the server node, and closing the voice recognition session corresponding to the application program on the terminal after the server receives the session closing result.
In one implementation, the server node may send a message to the application on the terminal that the session disconnection was successful after closing the speech recognition session.
In one implementation, the server node receives a session disconnection request of an application program during execution of a speech recognition algorithm for the application program on the terminal, and may then not send speech recognition algorithm results to the application program any more.
In this embodiment, the server node interacts with the cache server based on the session disconnection request, and the cache server executes the script once to update the current session number without multiple interactions, thereby improving the system performance and reducing the system pressure.
In one embodiment, after a server node in a cluster receives a connection request for implementing voice recognition, the receiving, by a cache server, session-related information sent by the server node for the connection request includes: a server node in a cluster acquires a service identifier described by a certificate and a session number threshold corresponding to the service identifier by reading the certificate of the service to which the imported connection request belongs; after receiving a connection request for realizing voice recognition, the server node generates session related information and sends the session related information to a cache server; the session related information comprises a service identifier and a session number threshold corresponding to the service identifier; and the cache server receives the session related information sent by the server node.
The session number threshold is an upper limit value of the session number of the same service at the same time. The server creates a speech recognition session based on a connection request of an application on a terminal.
Specifically, the server node may import at least one certificate of different services, obtain a service identifier described by the certificate and a corresponding session number threshold, and store the service identifier and the corresponding session number threshold in a local database. After receiving a connection request sent by an application program on the terminal, the server confirms a service identifier from the connection request, searches a corresponding session number threshold from a database based on the service identifier, generates session related information, and sends the session related information to the cache server.
In an embodiment, the server finds that the corresponding session number threshold is not obtained based on the service identifier, and sends a connection failure message to an application program on the terminal to notify that the service is not supported based on the imported certificate.
In this embodiment, the server node obtains the service identifier and the session number threshold by reading the imported certificate, and generates session related information including the service identifier and the session number threshold to the cache server for the connection request, so that the server node can limit the type of the accessed service and the session number threshold to which the service can be accessed according to the certificate.
In one embodiment, determining, by the script code, a current number of sessions of created sessions under a service to which the connection request belongs based on the session-related information includes: the cache server acquires a service identifier from the session related information through the script code; and searching the current session number corresponding to the acquired service identifier according to the corresponding relation between the pre-stored service identifier and the current session number.
Specifically, the cache server stores a data set in which service identifiers and the number of current sessions are in one-to-one correspondence. The cache server executes the code, obtains the service identification from the session related information, and searches the data set to obtain the current session number.
In one embodiment, the cache server searches for the current session number from the data set, adds a service identifier to the data set, and sets the current session number value corresponding to the service to 1.
In this embodiment, the number of current sessions is found by obtaining the service identifier in the session related information, and it is ensured that each service has a one-to-one correspondence to the number of current sessions, thereby implementing management of the number of sessions of different services.
In one embodiment, the session related information includes a current user identifier for initiating the connection request; the cache server stores a user identification set of the created session; the method further comprises the following steps: if the current user identification does not exist in the user identification set, executing a step of determining the current session number of the created session under the service of the connection request based on the session related information through a script code; if the current user identifier exists in the user identifier set, a third result is returned to the server node; a third result indicating that speech recognition is performed in response to the connection request.
Specifically, before the cache server returns the first result, the user identifier in the session related information is stored in the user identifier set.
Specifically, when receiving the session related information, the cache server obtains a current user identifier, and searches the current user identifier in the user identifier set. If the search fails, determining that the current user identifier is a new user identifier, and executing the step S204; if the search is successful, it indicates that the application program on the terminal corresponding to the current user identifier has already created a session. And returning a third result, and informing the server node that the voice recognition session is established.
In one embodiment, the server node receives the third result, determines that a speech recognition session has been created with the application, closes the previous speech recognition session, and re-establishes a new speech recognition session.
In one embodiment, when the cache server searches for or stores the user identifier, the refresh time of the user identifier is recorded as the current time. And the cache server judges the difference value between the refreshing time of the user identifier and the system time at intervals, judges that the application program on the terminal corresponding to the user identifier is offline after a preset active time is exceeded, and deletes the user identifier in the user identifier set. If the application program on the terminal corresponding to the user identifier initiates a voice recognition connection request, the step of S204 is also required.
In one embodiment, the cache server may prioritize different applications. The priority is high, the set active time is long, the priority is low, and the set active time is short. Specifically, the cache server extracts information of the application program from the user identifier, and sets corresponding active time.
In this embodiment, the cache server stores, reads, and determines the user identifier, which facilitates management and statistics of the application programs on different terminals, and enables the cache server in the cluster to limit the active time of the speech recognition sessions of different application programs.

At least one application program is installed on the terminal, and the application programs installed on different terminals can be the same or different, which is not limited.
Each user may use an application program on its own terminal, and when using the application program to perform voice recognition related operations, may send a connection request for implementing voice recognition to a corresponding server node through the application program, and the server node may send session related information to the cache server for the connection request, for example, may transmit information such as a session number threshold corresponding to a service to which the connection request belongs to the cache server. The cache server may run the script code, determine the current session number of the created sessions under the service, compare the current session number with the session number threshold, if the current session number is smaller than the session number threshold, the cache server may increase the current session number through the script code, and return a first result to the server node to indicate that the voice recognition session may be created for the connection request.
In one embodiment, the cache server may be a Redis server and the scripting code may be lua scripts.
