Currently, I am working on developing the iOS App that triggers an event upon voice command.
I saw a camera app, where a user says "start recording," then the camera starts to the recording mode.
This is an in-app voice control capability, so I am thinking it is different from SiriKit or SpeechRecognizer, which I have already implemented.
How would I achieve it?
My question is NOT the voice dictation where a user has to press a button to start dictation.
App needs to passively wait for a keyword, or intent, which is something like "myApp, start recording" or "myApp, stop recording", then the app starts/stop that event function accordingly.
Thanks.

Thank you.

There's an iOS 13 new feature called Voice Control that will allow you to reach your goal.
You can find useful information in the Customize Commands section where all the vocal commands are available (you can create a custom one as well):
For the example of the camera you mentioned, everything can be done vocally as follows:
I showed the items names to understand the vocal commands I used but they can be hidden if you prefer (hide names).
Voice Control is a built-in feature you can use inside your apps as well.
The only thing to do as a developer is eventually adapting the accessibilityUserInputLabels properties if you need specific names to be displayed for some items in your apps.
If you're looking for a voice command without pressing a button on iOS, the Voice Control is THE perfect candidate.

I have question to iOS Developers.
Does anybody know if Apple iOS Api allows to add new commands to build in iOS Voice Control engine. I noticed that Voice Control can control phone application using names, nicknames from address book. It can also play music list from default iOS music player app. I would like in my app to register new voice commands for this Voice Control engine and handle some actions based on recognized commands. I was searching in developer documentations but can't find anything like that. Am I missing something?

This is definitely possible thanks to the Customize Commands - Create New Command... menu:
If you need dedicated names to be read out for some items in your app, use the accessibilityUserInputLabels property to define them.
Following this rationale, you can now register new voice commands from your app to iOS Voice Control engine.
IOS till now not exposed any API's related to voice. However it is achievable using CMU Sphinx.
Big advantage of CMU Sphinx - it works offline.
I created a sample application that uses custom controls to take a picture. Now I want to take a picture using a voice command (like if the user says "capture photo"). Are there any default controls or options in iOS or do we need to implement our own? Any references?

It's now possible to take picture using the Voice Control feature in iOS app but only since iOS 13.
Are there any default controls or options in iOS or do we need to implement our own?
As of iOS 8, there is no Apple-provided speech-to-text API. You can use SpeechKit, or implement one of the hacks that uses the Google Voice API.
Currently I am developing an IOS app.I need once I open the camera through application then when i say "start recording" then recording should start automatically. Once i say "Cut" then it should stop. and ask for save video share etc.
My main concern is regarding voice command. recording should start stop through voice command.
Looking forward for experts suggestions.
Many Thanks
As Siri is not yet exposed to developers there are lot of third party sdks dat can be used for recognizing speech.
I have used
http://dragonmobile.nuancemobiledeveloper.com/public/Help/DragonMobileSDKReference_iOS/Introduction.html
There are number of other sdks too ,u can easily google them
U have to set the words dat u want to recognize and perform intended action.
All d best with your app!!
I have made an app that uses Openears framework to readout some text. But I haven't used any of Openears' speech recognition/speech synthesis features, just the talk to speech feature. My app got rejected by apple telling that the app asks for permission to use microphone while the app doesn't have any features of that kind. The following is the rejection message from apple:
During review we were prompted to provide consent to use the microphone, however, we were not able to find any features or functionality that use the microphone for audio recording.
The microphone consent request is generated by the use of either AVAudioSessionCategoryRecord or AVAudioSessionCategoryPlayAndRecord audio categories.
If you do not intend to record audio with your application, it would be appropriate to choose the AVAudioSession session category that fits your application's needs or modify your app to include audio-recording features.
For more information, please refer to the Security section of the iOS SDK Release Notes for iOS 7 GM Seed.
I have searched the app for AVAudioSessionCategoryRecord or AVAudioSessionCategoryPlayAndRecord audio categories as mentioned in the message but couldn't find any. How can I disable the prompting for permission to use microphone?
Your application got rejected because you don't need the microphone feature, openears by default interface with the use of the microphone feature hence why the user permissions came up. These user permissions are not dismissible as apple increased the security features for users so that they can be in more control of what they want their applications to be able to do. If you have to use OpenEars audio management feature for speech recognition see Update 1 otherwise continue on for a different solution using Apples Siri's Speech Synthesizer on iOS 7.
In your case, if all you want to do is read out some text, then you can use iOS7 Speech Synthesizer, which is the same synthesizer used to create Siri's voice.
It's SO easy to setup and I am currently using it for one of my projects to interact with the user via voice. Here's a quick tutorial on how to get it all setup:
Speech synthesizer tutorial
UPDATE 1
After #halle's comment, I decided to update the post for those that have to use the OpenEars framework who will be using only the FliteController Text To Speech feature without any sort of OpenEars speech recognition.
You can set the FliteController property noAudioSessionOverrides to TRUE so that you ensure that OpenEars wont interface with the Audio recording stream and this will stop the Microphone permissions alert from popping up.
[self.fliteController setNoAudioSessionOverrides:TRUE]
UPDATE 2
Based on #Halle's comment, you no longer need to do update 1:
Just an update that starting with today's update 1.65, FliteController won't ever make audio session calls on its own, so there is no further rejection danger here and it isn't necessary to set noAudioSessionOverrides.
I'm sorry your app was rejected. To use TTS only without any of the audio session management related to speech recognition in OpenEars, set FliteController's property noAudioSessionOverrides to TRUE. This will result in no audio session changes/no use of the mic stream.
I'll see if I can make the documentation for this setting a bit more prominent for developers doing TTS with OpenEars' FliteController only.
For completeness' sake, the documentation on how to greatly reduce your app binary size when using OpenEars, since that was also an issue for you:

http://www.politepix.com/openears/support/#Q_How_can_I_trim_down_the_size_of_the_final_binary_for_distribution
Edit: starting with today's version 1.65 of OpenEars and its plugins, if you just use FliteController there is no danger of rejection because the TTS classes no longer make any calls to the audio session by themselves. Thanks for the heads-up about this and, again, sorry you had a rejection due to this.
I would like to build a simple reader app for the iPad 2 that would allow users to navigate/read via voice controls. The app would allow the user to enter a mode where the microphone was live and listened for predefined keywords like 'down', 'up', 'next', 'back', 'home', etc.
I don't want to reinvent the wheel on this so I'm just wondering first, if someone has done this already and if not, are there any good tutorials or SDKs available to help with recording someone's voice, and then comparing future output to see if it matches, or just dealing with the microphone in general?
Let's put aside that this is a fairly vaguely worded question for the moment.
If you are expecting to allow voice control in your app that somehow works throughout the entire device, it's just not possible. Your app would only work to control itself -- or at least itself and whatever external hooks you can normally get to the rest of the device, like, say, playing a song out of the user's iTunes library.
If you're planning on doing this in a jailbroken environment, then you should find some open-source library that does voice recognition -- if there are any -- and start from there. Be prepared for a very long haul, though.
Dragon Mobile SDK is what you're looking for.
http://dragonmobile.nuancemobiledeveloper.com/
There maybe others voice recognition SDKs out there, but this is the only one I can think of from the top of my head.
You can find a library called CMU Sphinx. There's an iphone version for it called
PocketSphinx. See if it fits your needs.
I would like to build a simple reader app for the iPad 2 that would allow users to navigate/read via voice controls.
The iOS 13 new feature Voice Control fully meets your request because you can control your device and your app with your voice exactly the same as with touches.
It's also possible to define actions for some specific words for instance.
The device settings are perfectly well detailed to handle this amazing new feature (Accessibility - Voice Control):
If you need dedicated names to be read out in your app, use the accessibilityUserInputLabels property to define them.
That's definitely the built-in tool your need to reach your goal: no need to use external library or SDK, everything is natively provided. ;o)
