voice-rag 0.1.3

Provider-agnostic voice RAG pipeline. Plug in your voice provider, LLM, vector store, and document parsers.

voice-rag

Ingest your docs. Answer questions by voice. Deploy in minutes.

voice-rag is a Python library and CLI for building voice-powered RAG pipelines. Point it at a folder of documents, choose your LLM and voice provider, and get an OpenAI-compatible webhook ready to wire into ElevenLabs, Deepgram, or any voice platform.

pip install "voice-rag[elevenlabs]"
export OPENAI_API_KEY=sk-...
voice-rag init && voice-rag ingest ./docs --recreate && voice-rag serve
# → serving at http://localhost:8000/v1

---

What it does

your docs  →  Qdrant (hybrid dense + BM25)  →  retrieved chunks
                                                       ↓
voice platform  →  speech-to-text  →  /v1/chat/completions  →  LLM  →  TTS

Each turn from your voice platform hits the webhook, embeds the user utterance, retrieves the most relevant chunks, injects them into the system prompt, and streams the LLM response back as SSE — all in one pip install.

Install

# ElevenLabs voice + OpenAI LLM (most common)
pip install "voice-rag[elevenlabs]"

# All providers
pip install "voice-rag[all]"

# Pick only what you need
pip install "voice-rag[anthropic,pdf]"

Extra	Adds
elevenlabs	ElevenLabs voice adapter
deepgram	Deepgram voice adapter
anthropic	Anthropic (Claude) LLM client
gemini	Google Gemini LLM client
pdf	PDF parser (PyMuPDF)
docx	Word document parser
all	Everything above

---

Quickstart

# 1. Create a config file
voice-rag init

# 2. Ingest your documents (supports .md, .txt, .pdf, .docx)
voice-rag ingest ./docs --recreate

# 3. Start the webhook server
voice-rag serve

Point your ElevenLabs agent's Custom LLM URL to http://localhost:8000/v1.

By default, vectors are stored locally in .qdrant — no separate Qdrant server needed. Set vector_store.url to connect to a remote instance.

CLI reference

voice-rag init [--dir PATH]               # create voice-rag.yaml
voice-rag ingest <path> [--recreate]      # ingest a file or directory
voice-rag serve [--host] [--port] [--reload]
voice-rag query <text> [--limit N]        # test retrieval without a server
voice-rag inspect                         # show collection stats
voice-rag doctor                          # check API keys and Qdrant connectivity

---

Python API

from voice_rag import KnowledgeAgent, VoiceRagConfig

config = VoiceRagConfig()          # reads from voice-rag.yaml or env vars
agent = KnowledgeAgent(config=config)

agent.ingest("./docs", recreate=True)

app = agent.create_app()           # returns a FastAPI app
# run with: uvicorn app:app --port 8000

---

Configuration

Config is loaded from voice-rag.yaml (run voice-rag init to generate one) or environment variables. Environment variables override the YAML file.

Key	Env var	Default
llm.provider	LLM_PROVIDER	openai
llm.model	LLM_MODEL	gpt-4o-mini
llm.api_key / embedding.api_key	OPENAI_API_KEY	—
llm.base_url	LLM_BASE_URL	https://api.openai.com/v1
embedding.model	EMBEDDING_MODEL	text-embedding-3-small
vector_store.url	VECTOR_STORE_URL	empty → local .qdrant
vector_store.collection_name	VECTOR_STORE_COLLECTION_NAME	knowledge_base
server.port	SERVER_PORT	8000
server.enable_debug_retrieval	SERVER_ENABLE_DEBUG_RETRIEVAL	false

See voice-rag.yaml for the full annotated schema.
