Proto Interfaces Package

Synced from home2

Generated from home2/hri/proto_interfaces/README.md @ 7288a44 by scripts/sync_home2_readmes.py. Edit the README in home2 instead of this page.

This package contains Protocol Buffer definitions and gRPC service interfaces for the HRI microservices.

Contents

• speech_pb2.py / speech_pb2_grpc.py: Speech-to-Text service definitions
• tts_pb2.py / tts_pb2_grpc.py: Text-to-Speech service definitions

Usage

ROS2 Nodes

from proto_interfaces import speech_pb2_grpc, speech_pb2

# Create gRPC channel and stub
channel = grpc.insecure_channel("localhost:50051")
stub = speech_pb2_grpc.SpeechStreamStub(channel)

Microservices

from proto_interfaces import speech_pb2_grpc, speech_pb2

class WhisperServicer(speech_pb2_grpc.SpeechStreamServicer):
    def Transcribe(self, request_iterator, context):
        # Implementation
        pass
