Python SDK for DVGateway — real-time voice AI integration

Project description

dvgateway

DVGateway Python SDK — AI 음성 서비스를 실시간 전화 통화에 연결합니다.

설치

# 기본 SDK
pip install dvgateway

# AI 어댑터 포함 (Anthropic, OpenAI)
pip install dvgateway[adapters]

빠른 시작

import asyncio
import os
from dvgateway import DVGatewayClient
from dvgateway.adapters.stt import DeepgramAdapter
from dvgateway.adapters.llm import AnthropicAdapter
from dvgateway.adapters.tts import ElevenLabsAdapter

async def main():
    gw = DVGatewayClient(
        base_url="http://localhost:8080",
        auth={"type": "apiKey", "api_key": os.environ["DV_API_KEY"]},
    )

    await (
        gw.pipeline()
        .stt(DeepgramAdapter(api_key=os.environ["DEEPGRAM_API_KEY"], language="ko"))
        .llm(AnthropicAdapter(api_key=os.environ["ANTHROPIC_API_KEY"], model="claude-sonnet-4-6"))
        .tts(ElevenLabsAdapter(api_key=os.environ["ELEVENLABS_API_KEY"]))
        .start()
    )

asyncio.run(main())

Comfort Noise — AI 처리 중 Dead Air 방지

게이트웨이에서 GW_COMFORT_NOISE_ENABLED=true를 설정하면, AI 처리 중 무음 구간에 배경 소음이 자동으로 주입됩니다.

파이프라인 빌더 사용 시 자동 동작 (별도 코드 불필요):

# thinking:start/stop 시그널이 자동 전송됩니다
await (
    gw.pipeline()
    .stt(DeepgramAdapter(api_key="...", language="ko"))
    .llm(AnthropicAdapter(api_key="...", model="claude-sonnet-4-6"))
    .tts(ElevenLabsAdapter(api_key="..."))
    .start()
)

수동 제어:

# WebSocket 시그널 (저레이턴시)
audio_stream = gw.stream_audio(linked_id)
await audio_stream.send_thinking_start()  # 배경 소음 시작
# ... AI 처리 ...
await audio_stream.send_thinking_stop()   # 배경 소음 중단

# REST API
await gw.start_thinking(linked_id)
await gw.stop_thinking(linked_id)

요구사항
