Deploy and Host Pocket TTS on Railway

Pocket TTS is a text-to-speech engine from Kyutai Labs that runs entirely on CPU. No GPU needed. Send text to its API, get natural-sounding audio back in under 200 milliseconds. The model is 100 million parameters — small enough to run on two CPU cores, fast enough for real-time use.

About Hosting Pocket TTS

Pocket TTS runs as a Python service that loads a lightweight speech model into memory and serves an HTTP API. You send a text string, it returns an audio file. The model runs inference on CPU only, so it works on any Railway plan without GPU add-ons. Expect the service to use moderate CPU during synthesis and idle between requests.

Common Use Cases

Adding voice output to chatbots, virtual assistants, or notification systems
Building accessibility features that read content aloud for visually impaired users
Generating voice narration for articles, reports, or automated content
Prototyping voice interfaces without paying per-character for cloud TTS APIs

Dependencies for Pocket TTS Hosting

No external API keys required — the model runs locally on your Railway service
No GPU required — designed specifically for CPU inference
Python runtime with the model weights downloaded at build time

Why Deploy Pocket TTS on Railway?

Railway is a singular platform to deploy your infrastructure stack. Railway will host your infrastructure so you don't have to deal with configuration, while allowing you to vertically and horizontally scale it.

By deploying Pocket TTS on Railway, you get an always-on speech API that your other services call whenever they need to generate audio. No GPU costs, no per-character billing, and Railway handles scaling when traffic spikes.
