kaldigrpc-client

Kaldi gRPC client

Python client library for Kaldi gRPC server. This client has similar - identical - semantics to the Google speech Python library.

Installation

You can install from source

git clone https://github.com/georgepar/kaldi-grpc-server
cd client
pip install .

or from Pypi

pip install kaldigrpc-client

Usage from command line

We assume you have a server running on port 50051. See kaldi-grpc-server README for more information.

kaldigrpc-transcribe --port 50051 $MY_WAV_FILE

For long files we recommend using the streaming client

kaldigrpc-transcribe --streaming --port 50051 $MY_WAV_FILE

Programmatic usage

The following is a simple example for streaming recognition using the ILSPASRClient. You can also refer to the code and the proto files for more configuration options and more outputs (e.g. confidence, word start and end times etc.)

Warning: Some configuration options are included for compatibility / easy swapping with the Google Speech client library but are not yet fully implemented. Please refer to the code for more details.

cli = ILSPASRClient(host="localhost", port=50051)

chunks = ...  # list of audio chunks (bytes)

for partial_result in cli.streaming_recognize(chunks):
    # Print best path partial transcription
    print(partial_result.results[0].alternatives[0].transcript)
