Introduction

Overview

The TextToSpeech SDK provides a voice synthesis feature based on a voice interface by supporting the integration of applications running on the 42dot Pleos Vehicle OS with the 42dot voice synthesis platform. The SDK transmits text to the Speech Service platform according to the API format provided by the TextToSpeech SDK and delivers the synthesized voice results from the Speech Service platform back to the client. The TextToSpeech SDK allows playback of desired text using the audio system in the car environment.
