talkies
Self-hosted speech services in one Docker image: OpenAI-compatible file transcription and text-to-speech, Talkies live ASR over WebSocket, file staging, model lifecycle controls, and an MCP endpoint for ASR workflows.
Start here
Restrict the first boot to the models you need; otherwise the entrypoint downloads every model in the bundled registry.
docker run --rm -it --name talkies \
-p 127.0.0.1:8000:8000 \
-v "$PWD/talkies-data:/data" \
-e TALKIES_ENABLED_MODELS=whisper-large-v3-turbo,kokoro-82m \
psyb0t/talkies:latest
curl -s http://127.0.0.1:8000/healthz
curl -s http://127.0.0.1:8000/v1/audio/transcriptions \
-F "file=@/path/to/clip.wav" \
-F "model=whisper-large-v3-turbo"
For CUDA-only models and Qwen3 TTS, use psyb0t/talkies:latest-cuda with
--gpus all. The loopback port mapping keeps the service local; see
Getting started for first boot and authentication.
What it provides
| Surface | Purpose | Reference |
|---|---|---|
POST /v1/audio/transcriptions | File transcription and subtitles | HTTP API |
WS /v1/audio/transcriptions/stream | Live 16 kHz PCM ASR | Streaming |
POST /v1/audio/speech | Speech synthesis in six formats | HTTP API |
GET/PUT/DELETE /v1/files/* | Server-side file staging | HTTP API |
/api/ps, /unload | Model inspection and eviction | Operations |
/v1/mcp | Streamable HTTP MCP with ASR/file tools | HTTP API |
The HTTP transcription and speech routes use the corresponding OpenAI wire shapes where those contracts overlap. Streaming ASR, files, lifecycle controls, and MCP are Talkies extensions.
Models at a glance
- CPU: two Whisper models, Canary-180M-Flash, Nemotron ASR via parakeet.cpp, four English Sherpa-ONNX Zipformer choices, Vosk small English, and two Kokoro TTS backends.
- CUDA: the CPU set plus Parakeet-TDT, Canary 1B/Qwen ASR, and five Qwen3 TTS variants.
- Live ASR: bundled Nemotron, Sherpa-ONNX, and Vosk are native; bundled Whisper is a bounded rolling decoder. Sherpa and Vosk also work through the OpenAI-compatible file-transcription endpoint.
- Per-model concurrency limits cover WebSocket, HTTP, MCP, ASR, and TTS; the bundled Nemotron CPU and CUDA entries admit two requests.
- Streaming TTS: Qwen3 returns incremental raw PCM for
response_format="pcm"; other TTS formats and Kokoro are buffered.

Agent integrations
The Talkies skill teaches agents to use the HTTP,
WebSocket, and MCP surfaces. Install it through the shared psyb0t marketplace
or let Codex discover it directly from this checkout.
Claude Code
claude plugin marketplace add psyb0t/agents
claude plugin install talkies@psyb0t
Claude Code prompts for the Talkies URL and, when enabled, the bearer token; the sensitive token is stored through the client's protected configuration.
Codex
codex plugin marketplace add psyb0t/agents
codex plugin add talkies@psyb0t
A marketplace install invokes the skill as $talkies:talkies. Codex also
discovers .agents/skills/talkies directly in this repository, where it is
invoked as $talkies without installation.
OpenClaw
The skill and MCP bridge are published through ClawHub:
openclaw skills install @psyb0t/talkies
openclaw plugins install clawhub:@psyb0t/talkies
The bridge connects local stdio MCP clients to a running Talkies /v1/mcp
endpoint. Set TALKIES_URL and, when authentication is enabled,
TALKIES_AUTH_TOKEN.
Security in one minute
TALKIES_AUTH_TOKEN enables a shared bearer token for every HTTP and WebSocket
route except /healthz. It is unset by default. Keep the port loopback-only or
put Talkies behind TLS, authentication, and rate limiting. If untrusted callers
can supply remote file_path URLs, set TALKIES_BLOCK_PRIVATE_DOWNLOADS=true.
See Operations and security for the complete posture.
Development
make check # lint + unit tests in the dev image
make test-streaming # real CPU native WebSocket ASR test
make test-streaming-custom # real CPU Sherpa/Vosk WebSocket + HTTP tests
make test-streaming-custom-cuda # real CUDA Sherpa WebSocket + HTTP test
make build-all # CPU and CUDA production images
Talkies is released under the WTFPL. Model weights are downloaded at runtime and have their own terms; image component notices are in THIRD_PARTY.md. Release notes are in CHANGELOG.md.
