SKRecognition: This object contains voice recognition results, scores corresponding to each recognition result and suggestions for the user.Generate a new instance of this class for any subsequent recognition.
Only one recognition process happens at any point of time. It records the user’s voice, transmits it to Nuance Speech server and obtains lists of matching texts.
SKRecognizer: This is the primary class for voice recognition. The SpeechKit iOS framework has the following four classes and three protocols that it uses for speech recognition and text-to-speech synthesis. Both male and female voices are available for many languages. SpeechKit supports 38 languages for speech recognition and 40 languages for the text-to-speech synthesis. To convert text to speech, the SKVocalizer class sends the text to a server and receives an audio playback. For voice recognition, the SKRecognizer class sends audio streams to the server which then returns a list of text results. SpeechKit follows a server-based architecture and relies on the Nuance speech server for voice recognition and text-to-speech synthesis. The encoding component manages the streaming audio’s compression to reduce bandwidth requirements and decrease latency. The end-of-speech detector determines when the user stops speaking and automatically stops recording. The networking component manages the connection to the server and automatically re-establishes timed-out connections. The audio component manages the audio system for recording and playback to give user feedback. The framework carries out the following processes: The SpeechKit framework is a high-level framework with two major components for developers: the speech recognizer and the text-to-speech synthesizer. Here’s a demo video of the app you will be building: You’ll use this knowledge to build a Siri-like application to help your users find nearby restaurants, narrowed down by cuisine or category. #Siri voice generator app how to#
How to perform speech recognition and text-to-speech synthesis using SpeechKit APIs.The advantages of SpeechKit when compared to other frameworks.The key concepts of SpeechKit framework.In this tutorial, you’ll learn how to use the Nuance Dragon Mobile SDK (SpeechKit), which is one of the leading frameworks in this arena. Unfortunately at the time of writing this tutorial there isn’t an official API by Apple, but there are few third party frameworks that allow developers to include functionality similar to Siri. Siri is a voice-based personal assistant that takes voice commands and performs tasks like sending messages, making phone calls, setting alarms, searching on the web, finding directions and more.
