The Speech Recognition API provides results back to the calling app in near real-time as the user is speaking and it provides more information about the results of translation than just text. The results provided by the Speech Recognition API are transparently customized to the individual users, without the app having to collect or access any private user data. This API is the same one that Apple uses to power both Siri and Keyboard Dictation and it is capable of providing fast transcription with state of the art accuracy. New to iOS 10, Apple has released the Speech Recognition API which provides a more powerful way for an iOS app to implement speech recognition. It provides a very shallow set of results that lacks information such as timing and confidence.The app cannot customize the audio recording process.There is no way for the app to know if the Dictation button is even available to the user.It provides no control over the language that is used to interpret the user's speech.It works with live audio input only and the app has no control over the audio recording process.It requires the use of a Text Input Field and display of a keyboard.While Keyboard Dictation is easy to implement, it does come with several limitations and disadvantages: Please see our Security and Privacy Enhancements documentation for details. Keyboard Dictation also has the advantage of not requiring any special privilege requests from the app before it can be used.Īpps that use the new Speech Recognition APIs will require special permissions to be granted by the user, since speech recognition requires the transmission and temporary storage of data on Apple's servers. Keyboard Dictation is extremely easy to use as it requires no effort on the developer's part, other than using a TextKit interface element in the app's UI design. About a third of all iOS Dictation is done in a 3rd party app.Approximately 65,000 apps use it per day.Keyboard Dictation has been widely used since it was released in iOS 5.Keyboard Dictation is supported by any interface element that supports TextKit (such as UITextField or UITextArea) and is activated by the user clicking the Dictation Button (directly to the left of the spacebar) in the iOS virtual keyboard.Īpple has released the following Keyboard Dictation statistics (collected since 2011): When most users think of Speech Recognition on an iOS device, they think of the built-in Siri voice assistant, which was released along with Keyboard Dictation in iOS 5 with the iPhone 4S. Speech Recognition is implemented in an iOS app by acquiring either live or pre-recorded audio (in any of the spoken languages that the API supports) and passing it to a Speech Recognizer which returns a plain-text transcription of the spoken words. New to iOS 10, Apple has release the Speech Recognition API that allows an iOS app to support continuous speech recognition and transcribe speech (from live or recorded audio streams) into text.Īccording to Apple, the Speech Recognition API has the following features and benefits:
