Rust Verbio SpeechCenter Client

How to build

In order to build the system

$ cargo build --release --all

It will build two binaries: batch-client and cli-client.

How to use

CLI client

The CLI client allows you to launch a single file to the server. It also allows you to use either a grammar or a language model.

λ ./target/release/cli-client --help
cli-client 0.1.0

USAGE:
    cli-client [OPTIONS] --audio

An example execution could be:

λ ./target/debug/cli-client -a example.wav -l en-US -t my.token -T generic

Batch client

The batch client iterates over wav files inside a directory, sends them in parallel to the server and stores the transcription in another directory.

λ ./target/release/batch-client --help
batch-client 0.1.0

USAGE:
    batch-client [OPTIONS] --dest-dir 
   
     --language 
    
      --dir 
     
       --token-file 
      
        --topic 
       
         --url 
        
          FLAGS: -h, --help Prints help information -V, --version Prints version information OPTIONS: -D, --dest-dir 
         
           Destination directory for the transcriptions -l, --language 
          
            Language to use for the recognision [default: en-US] -L, --log-level 
           
             Log level. Must be TRACE | DEBUG | INFO | WARN | ERROR [default: info] -d, --dir 
            
              Directory containing audios to use for the recognision -t, --token-file 
             
               Path to the token file -T, --topic 
              
                Topic to use for the recognision. Must be GENERIC | BANKING | TELCO -u, --url 
               
                 URL of the server [default: https://speechcenter.verbio.com:2424] -w, --workers 
                
                  Number of workers to use for the recognision [default: 4]

An example execution could be:

λ ./target/release/batch-client -w 4 -d ~/tmp/commonvoice/clips -D /tmp/results -t my.token -T generic --log-level debug

Improvements to be done

Right now, the build process generates the speech-center-client/src/csr_grpc_gateway.rs file. However, the tonic-build is able to generate it into the target directory and include it via macros. Unfortunately, my IDE was not able to detect the file, so autocomplete didn't work and I prioritized developer ergonomy over "correctness" for this PoC (sorry guys).

In order to change it, edit the build.rs and see the documentation of tonic-build.
