# Introduction

Pinch is an API for speech translation. We offer two products:

**Real-time translation** — open one WebSocket, stream microphone audio in, receive translated audio and transcripts back live. Choose speech-to-speech or speech-to-translated-text per session. No SDK required.

**Dubbing** — submit audio or video, get back a fully dubbed version in another language. Asynchronous REST API with per-minute pricing.
