This package lets you use speech-to-text OS engine.
On Apple devices it uses engine introduced in iOS10 – you still might target devices with iOS lower than 10 and use simple API to check if engine is supported.
Extremely simple API:
– Works on both iOS (>=10) and Android (>=3.0),
– Gives you final and partial recognition results,
– Lets you check if current device supports speech recognition with simple API: SpeechRecognizer.EngineExists(),
– Doesn’t require Unity PRO,
– Easy integration
