Text-to-Speech

Convert text to natural speech via inference.sh CLI.

Quick Start

# Install CLI
curl -fsSL https://cli.inference.sh | sh && infsh login

# Generate speech
infsh app run infsh/kokoro-tts --input '{"text": "Hello, welcome to our product demo."}'

Install note: The install script only detects your OS/architecture, downloads the matching binary from dist.inference.sh, and verifies its SHA-256 checksum. No elevated permissions or background processes. Manual install & verification available.
