Simple Voice Recognition Swift? [closed]

Question

In my app when the user says a certain word or words the app will answer by reading out a sentence which is set in app. What is the simplest way of doing this?

I'm using the latest version of Xcode (Its for my WWDC 2015 scholarship app)

Answer 1

you can use

OpenEars SDK http://www.politepix.com/openears/

or

Answer 2

As of iOS 10 you can use Speech.framework:

import Speech

let recognizer = SFSpeechRecognizer()
let request = SFSpeechURLRecognitionRequest(url: audioFileURL)
recognizer?.recognitionTask(with: request, resultHandler: { (result, error) in
     print (result?.bestTranscription.formattedString)
})

Baler

what is this audioFileURL – Norseman

The URL of the audio file you want to be recognized. You can also use an audio buffer if you want real time recognition – Baler

But Speech framework has limitation of one minute recording. And how to achieve for long audio file. Like recording from time to time in the audio file. – Obligato

Answer 3

You'll want to use SpeechKit. Ray has a nice tutorial here:

The SDK is developed by Nuance (the dragon people):

My app is coded in Swift, a lot of people including me had a lot of trouble trying to get speechKit to work on swift. Would you perhaps know any other tutorials in swift? Thanks a lot! – Greg

@Greg You can always use Objective-C and Swift together in the same application. Simply write the parts interfacing with SpeechKit in Objective-C then interface with that using a bridging header. I don't know of any other good tutorials that I'd recommend but I'll keep looking – Sauer

I´m struggling to make my Swift app use Speechkit. Initializing works fine but I cant figure out how to implement override callback methods from SpeechKit (didFinishWithErrors, didFinishWithResults, etc) into the .swift code. Just adding those methods to a protocol won´t do, you can add methods there, but it does not make any sense. – Priorate

Well I have used SpeechKit in my Swift app working perfectly. – Tunisia

@Tunisia can you please post your Swift based implementation (either here or in a new new SO post, please?) – Moitoso

@Moitoso there is a simple example here that works in Swift 2. – Manvel
