+title: "Pinch"
+description: "Real-time translation service implementation using Pinch's speech-to-speech API"
+---
+
+## Overview
+
+`PinchAudioService` provides real-time speech translation with synchronized audio output and transcription capabilities. The service translates spoken audio from one language to another while maintaining natural conversation flow through streaming audio processing.
+
+The service provides:
+- **Real-time Translation**: Stream audio input and receive translated audio output with minimal latency
+- **Dual Transcription**: Both source language transcription and translated text output
+- **Voice Synthesis**: Natural-sounding translated speech with customizable voice parameters
+- **Streaming Architecture**: Optimized for low-latency conversational applications
+
+## Installation
+
+To use `PinchAudioService`, install the required dependencies:
+
+```bash
+pip install "pipecat-ai[pinch]"
+```
+
+You'll also need to set up your Pinch API token as an environment variable: `PINCH_API_TOKEN`.
+
+
+ Get your API token by creating an account at [Pinch](https://www.startpinch.com/).
+
+
+## Frames
+
+### Input
+
+
+ Raw PCM audio data for speech input (16-bit, 16kHz, mono)
+
+
+### Output
+
+
+ Final transcription of the source language speech
+
+
+
+ Real-time partial transcription updates during speech
+
+
+
+ Translated text output in the target language
+
+
+
+ Text being synthesized to speech in the target language
+
+
+
+ Translated audio stream chunks (16-bit PCM)
+
+
+## Configuration
+
+### Constructor Parameters
+
+
+ Pinch API authentication token
+
+
+
+ HTTP client session for WebSocket connections and API requests
+
+
+
+ Session configuration object. Defaults to English → Spanish translation with female voice
+
+
+### Session Configuration
+
+The `PinchSessionRequest` object configures the translation session:
+
+
+ Input language code (e.g., "en" for English). See supported languages below
+
+
+
+ Output language code (e.g., "es" for Spanish). See supported languages below
+
+
+
+ Voice characteristic for synthesized speech. Options: "female", "male"
+
+
+
+ Whether to generate translated audio output. Default: `True`
+
+
+
+ Whether to output transcription frames. Default: `True`
+
+
+
+ Audio sample rate in Hz. Default: `16000`
+
+
+## Language Support
+
+Pinch supports real-time translation between a growing number of language pairs. We are constantly adding new languages and improving translation quality.
+For a complete list of supported languages and available translation pairs, please visit the [Pinch documentation](https://www.startpinch.com/).
+
+## Usage Example
+
+```python
+from pipecat.transports.pinch.api import PinchSessionRequest
+from pipecat.services.pinch import PinchAudioService
+
+pinch_api_key = os.getenv("PINCH_API_KEY")
+
+# Configure session
+session_request = PinchSessionRequest(
+ source_language="en",
+ target_language="es",
+ voice_type="female",
+ enable_audio_output=True
+)
+
+# Create Pinch audio streaming service
+pinch_service = PinchAudioService(
+ api_token=pinch_api_key,
+ session=session,
+ session_request=session_request
+)
+
+# Create pipeline
+pipeline = Pipeline([
+ transport.input(), # Audio input
+ pinch_service, # Translation service
+ transport.output(), # Audio output
+])
+```
