Synthesize speech against the user's own host-native audiocpp_server build (outside the GuideAnts container) — including model families the container binary lacks, like Kokoro or Parakeet forks. TTS only. Use when the user says they run their own audio.cpp server or asks for a family the container build cannot load.

audio.cpp host-native engine (experimental)

The sandbox can reach an audiocpp_server the user runs natively on the host — same raw API as the container engines, but with whatever models and loaders their build has (e.g. a fork compiled with Kokoro enabled). Deliverables are WAV files in Output/.

Preflight

python3 Output/Skills/audiocpp-host-tts/scripts/preflight.py --for host-tts

Resolution order: AUDIOCPP_ENGINE_URL env (set via the guide editor's Environment variables UI), else http://host.docker.internal:8080. The preflight also distinguishes a real audio engine from a llama-server that happens to answer /health on the same port.

Synthesizing

--model is required — there is no wrapper to auto-detect from:

python3 Output/Skills/audiocpp-host-tts/scripts/engine_tool.py speech "Hello" \
  --engine-url http://host.docker.internal:8080 --model <engine-model-id> \
  -o Output/hello.wav [--voice <id>] [--seed 42] [--language en] [--voice-ref ...]

List the models the host build serves: GET <base>/v1/models; voices: engine_tool.py voices --engine-url <base> --model <id>.

The consent rule applies to --voice-ref cloning here too: proceed for the user's own voice or a consenting speaker; decline third-party imitation.

Hard limit: TTS only

The host engine's /v1/audio/transcriptions takes a server-local path in its JSON body — files in this sandbox are not visible to the host process, so transcription against the host engine cannot work from here. Use the container ASR (the audiocpp-asr-extended skill) instead.

Troubleshooting

Symptom	Likely cause	What to do
Unreachable	Server not bound to `0.0.0.0`, or Windows Firewall blocking the Docker adapter	Ask the user to check both
`/health` 200 but no `/v1/audio/*`	A llama-server on that port, not audiocpp	Ask which port their audio.cpp build listens on
Model errors	Family/option mismatch in their build	Surface the engine's error text — it names the problem

Reporting

End by telling the user what worked and what was blocked, quoting the preflight/engine evidence.

audiocpp-asr-extended

Elumenotion/GuideAnts

Transcription beyond the GuideAnts wrapper contract: transcribe workspace files by path (no upload, no 50 MB gateway cap), pass language hints, and sideload other qwen3-family ASR snapshots from Hugging Face through the wrapper. Use when a transcription needs a language hint, the file is large, or the user wants to try an ASR model the catalog doesn't list.

audiocpp-deferred-tts

Elumenotion/GuideAnts

Run TTS model families audio.cpp supports but GuideAnts does not ship — Qwen3 CustomVoice builtin speakers, VibeVoice multi-speaker dialogue, MioTTS, VoxCPM2, PocketTTS, Vevo2 voice conversion — by downloading the model and spawning a private audiocpp_server in the sandbox. Use when the user names one of these models or asks for a TTS capability the loaded catalog model rejects.

2026-07-2046

audiocpp-diarize

Elumenotion/GuideAnts

Speaker diarization: figure out who spoke when in a recording and produce a speaker-labeled transcript, by spawning a private audio.cpp engine with the sortformer diarization model and labeling each turn with the local ASR engine. Use when the user asks to diarize a meeting or call recording, separate or identify speakers, or wants a transcript broken down by speaker.

2026-07-2046

audiocpp-extended

Elumenotion/GuideAnts

Experimental: use audio.cpp scenarios and models that GuideAnts does not ship — speaker diarization (who spoke when, speaker-labeled transcripts), voice cloning from user-supplied audio, deterministic seeds, builtin speakers, language forcing, and deferred TTS families (Qwen3 CustomVoice, VibeVoice, MioTTS, VoxCPM2, PocketTTS) — by calling the raw audiocpp_server engines directly or spawning a private engine in the sandbox. Use when the user asks for a voice, model, or audio scenario the built-in audio tools reject or cannot express, including diarizing a meeting recording or labeling speakers in a transcript.

audiocpp-tts-controls

Elumenotion/GuideAnts

Advanced synthesis controls on the loaded audio.cpp TTS model: deterministic output via seed, forcing the spoken language, voice-design from a text description (instructions), and enumerating builtin speaker ids — none of which the built-in GuideAnts audio tools expose. Use when the user wants reproducible audio, a specific language, a described voice, or a list of available speakers.

audiocpp-voice-clone

Elumenotion/GuideAnts

Clone a voice from a user-supplied reference clip and synthesize speech with it, by calling the raw audio.cpp TTS engine with voice_ref/reference_text — fields the built-in GuideAnts audio tools do not expose. Use when the user wants generated speech to sound like their own voice or another consenting speaker's recording.
