Introduction

Overview

The SpeechToText SDK provides a voice recognition feature based on a voice interface by enabling integration with the 42dot voice recognition platform in applications running on the 42dot Pleos Vehicle OS. The SDK transmits the user's voice to the Speech Service platform according to the API format provided by the SpeechToText SDK and delivers the processed text results from the Speech Service platform back to the client. By using the SpeechToText SDK, IVI applications can utilize the 42dot voice recognition service without needing to manage microphone control or handle input and output operations.
