Overview

AI-generated overview

Self-hosted Docker speech server exposing an MCP endpoint so an assistant can transcribe audio files and stage files for ASR workflows.

What you can do
  • Transcribe audio files and produce subtitles through the OpenAI-compatible transcription route, including phoneme output from IPA models
  • Stage, list and delete server-side files used as transcription input
  • Inspect enabled models and their modality, and unload models to free memory
  • Beyond MCP, the same service offers text-to-speech synthesis, live WebSocket ASR, and voice cloning from clips dropped into a data folder
When to use it
Use it when you want speech-to-text inside an assistant but keep audio on your own machine instead of sending it to a hosted API, and you are comfortable running a Docker container with downloaded model weights.
Requirements
A local Docker runtime; the image is published as psyb0t/talkies and served over streamable HTTP on port 8000, typically mapped to loopback. A CUDA image and GPU access are needed for the larger models. Model weights are downloaded at runtime, and TALKIES_ENABLED_MODELS limits which ones are fetched on first boot. Optional bearer token via TALKIES_AUTH_TOKEN.
Before you install
Authentication is off by default, so any route except the health check is open unless TALKIES_AUTH_TOKEN is set; keep the port loopback-only or behind TLS. First boot downloads every model in the bundled registry unless restricted. File staging tools can write and delete files on the server, and remote file_path URLs can be fetched, so TALKIES_BLOCK_PRIVATE_DOWNLOADS should be set if untrusted callers supply URLs. Model weights carry their own terms.

Installation

In SourceWeft

  1. Open Talkies in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

[CI] [version] [license] [Docker Pulls]

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.

Contents

Start here

Restrict the first boot to the models you need; otherwise the entrypoint downloads every model in the bundled registry.

bash
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/healthzcurl -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 — Parakeet-TDT, the larger Canary models, Qwen3 TTS and Chatterbox Turbo — 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

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, two phoneme recognizers, and two Kokoro TTS backends.
  • CUDA: the CPU set plus Parakeet-TDT, Canary 1B/Qwen ASR, five Qwen3 TTS variants, and Chatterbox Turbo.
  • 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.
  • Phoneme recognition: wav2vec2-xlsr-53-espeak and zipa-ipa return the IPA phones that were spoken, not words, with no language model correcting them toward the nearest dictionary entry. Same transcription endpoint and timestamp options as the other ASR models; see Phoneme recognition.
  • 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.
  • Expressive TTS: Chatterbox Turbo (English) takes 19 inline tags such as [sigh], [whispering] and [laugh] directly in the input text. Its output carries a neural watermark by default; set TALKIES_CHATTERBOX_WATERMARK to false to emit unmarked audio.
  • Voice cloning: drop a .wav into /data/custom-voices and it appears on GET /v1/audio/voices. Qwen3 pairs it with an optional sibling .txt transcript; Chatterbox needs only the clip, longer than five seconds.

Exact slugs, executors, tag list, and registry format: Models and registries.

Reading phonemes

wav2vec2-xlsr-53-espeak and zipa-ipa use the same transcription call as every other ASR slug; only the model changes. text comes back as a space-separated IPA phone stream rather than words, and no language model corrects a mispronunciation toward a real word.

bash
curl -s http://127.0.0.1:8000/v1/audio/transcriptions \  -F "file=@/path/to/clip.wav" \  -F "model=zipa-ipa"# {"text": "a ɪ m k ə n f j u z ...", ...}

Add -F "response_format=verbose_json" (or timestamp_granularities[]=word) to get each phone as a words entry with start and end in seconds.

Prompting Chatterbox with emotion

Tags go inline in input, in square brackets, lowercase. They are real tokens in the model's tokenizer, so only these 19 do anything — any other bracketed word is spoken as literal text:

[angry] [fear] [surprised] [whispering] [advertisement] [dramatic] [narration][crying] [happy] [sarcastic] [clear throat] [sigh] [shush] [cough] [groan][sniff] [gasp] [chuckle] [laugh]
bash
curl -s http://127.0.0.1:8000/v1/audio/speech \  -H 'Content-Type: application/json' \  -d '{        "model": "chatterbox-turbo",        "voice": "builtin",        "input": "Oh, that is hilarious. [chuckle] Anyway [sigh] back to work.",        "response_format": "mp3"      }' --output out.mp3

Swap "voice" for the name of any .wav you dropped in /data/custom-voices (extension stripped) to speak the same line in a cloned voice.

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

bash
claude plugin marketplace add psyb0t/agentsclaude 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

bash
codex plugin marketplace add psyb0t/agentscodex 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:

bash
openclaw skills install @psyb0t/talkiesopenclaw 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

bash
make check                 # lint + unit tests in the dev imagemake lint                  # flake8 + mypy onlymake test-unit             # fast offline unit testsmake run                   # run the CPU image locallymake test-streaming        # real CPU native WebSocket ASR testmake test-streaming-custom # real CPU Sherpa/Vosk WebSocket + HTTP testsmake test-streaming-custom-cuda # real CUDA Sherpa WebSocket + HTTP testmake compile-heavy         # regenerate the hash-locked ML requirementsmake build-all             # CPU and CUDA production images

make help lists every target.

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.
