Convert text to speech using ElevenLabs voice AI through Letta. Use when generating audio from text, sending a voice message, reading text aloud, creating voiceovers, speaking in your own voice, or synthesizing speech in 90+ languages.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# ElevenLabs Text-to-Speech (via Letta)
Generate natural speech from text - supports 90+ languages, multiple models for quality vs latency tradeoffs. Examples default to `eleven_v4`, the latest and highest-quality model.
This skill is adapted from ElevenLabs' `text-to-speech` skill
([elevenlabs/skills](https://github.com/elevenlabs/skills), MIT; see `LICENSE`).
Instead of calling ElevenLabs with your own key, you call Letta's hosted endpoint
`POST /v1/audio/speech`. It forwards the request to ElevenLabs with Letta's key
and charges the organization's Letta credits, so you do not need an ElevenLabs
API key. The request body uses the same field names as ElevenLabs "Create
speech" (the voice ID and `output_format` go in the body), and the response is
the audio file itself, as with ElevenLabs.
## Quick Start
```bash
base_url="${LETTA_BASE_URL%/}"
curl -sS -X POST "$base_url/v1/audio/speech" \
-H "Authorization: Bearer $LETTA_API_KEY" \
-H "Content-Type: application/json" \
-d '{"text":"Hello, welcome to ElevenLabs!","voice_id":"JBFqnCBsd6RMkjVDRZzb","model_id":"eleven_v4"}' \
--output output.mp3 \
--dump-header speech-headers.txt \

How to install
mdr add letta-ai/letta-code/speech-generation@sha256:cf892cc067eec487The line at the top of this page pins the label git:20261102.408bca2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
