Piper TTS hosting
Fast neural text-to-speech that runs comfortably on CPU.
Piper TTS hosting at AIHostBox means a dedicated, single-tenant Piper TTS instance on our infrastructure: we install it, pin it to a reviewed release, put it behind TLS on your domain, back it up nightly and keep it patched. Plans start at $5.99 per month and the admin account, the data and any API keys are yours.
Piper is a neural text-to-speech engine that began in the Rhasspy voice-assistant project and is now developed under the Open Home Foundation as piper1-gpl, the voice engine used by Home Assistant. It runs compact ONNX voice models and uses espeak-ng for phonemisation, which is why it can speak faster than real time on an ordinary CPU with no GPU at all. Voices come in several quality levels and cover more than 40 languages.
The engine is small, but hosting it earns its keep once more than one thing needs a voice. A single HTTP endpoint on port 5000 accepts text and returns WAV audio, so an automation, a website and an internal tool can all share the same voices without each one bundling the model. It also means no per-character bill: a million characters a month costs the same as a hundred, and the text never leaves your instance.
Piper TTS hosting plans
Every plan is a dedicated single-tenant instance with NVMe storage, nightly off-box backups, TLS and managed patching. Quarterly, semi-annual and annual terms are discounted at checkout. Model tokens are not included — you bring your own key.
How we run Piper TTS
The Piper Python package running its built-in HTTP server (python -m piper.http_server) on port 5000, with downloaded voice models in a persistent data directory; no database.
What we configure for you
- Default voice set with -m, plus the extra voices you ask for downloaded to the data directory
- Default speaking speed (length_scale) tuned to your use
- Authentication in front of the endpoint, since Piper’s server has none of its own
- Voice files included in the nightly backup so a restore does not need re-downloads
Which plan fits
Starter (2 GB, 1 vCPU) handles notifications and on-demand narration with a few medium voices. Plus (4 GB) keeps more voices ready and copes with several requests at once; Pro (8 GB) is for batch-converting long texts or serving high-quality voices to many users.
The honest limits
The maintained code is GPL-3.0 (the original MIT repository was archived in 2025), and individual voices have their own licences. Piper does not clone voices or produce expressive, emotional speech; it reads text clearly in the voice you pick.
