context bias for each websocket request

[anjul1008]

Hi All,

I'm trying to implement context biasing for each websocket request with user provided words. i have made a few changes in wesocket_server.cc file to accept user context strings and score to build graph. And graph bulding is perfomed in OnSpeechStart() method.

But looks graph is not updated with newly build graph, it remains same which is build while loading model from params.h.

here are the screenshots of code change:

Can anyone help me to resolve it, any help would be appreciated.

Hi @pengzhendong

i have tried the other approach to, i have added a new method void ContextGraph::UpdateContextGraph(std::string on_request_context_words_, float on_request_context_score_, const std::shared_ptr<fst::SymbolTable>& unit_table) in
context_graph.h header file, which can be called from OnSpeechGraph() method in wesocket_server.cc.

but it leads to following compilation error:

Can you please suggest me the where i'm making mistake or better approach to handle request level context graph creation.

Hi @Mddct, i made changes as described above but the context graph is updated which is shared across active connections. i'll working on it and need to make major changes with shared context resources to non shared websocket connection.

your guidance would be very helpful if you have time.

thank you.
